| 00:25:28 | pmisfit | heh. it is alive. http://www.246gt.com:8030/projects/tuxscreen/frankenboard/ |
| 00:25:50 | pmisfit | does end-zone dance |
| 00:33:06 | moritz_ | does anyone have any experience with LART? |
| 00:43:08 | Russ|werk | I sorta do |
| 00:44:22 | Russ|werk | pmisfit: what does -kr2 entail? |
| 00:48:05 | moritz_ | Russ|werk, what did you pay for all parts needed for lart? |
| 00:49:12 | Russ|werk | its *highly* dependant on quantity |
| 00:49:26 | Russ|werk | I think with 25 of a similar board, parts were 250? |
| 00:49:32 | Russ|werk | (per) |
| 00:49:39 | Russ|werk | I'm not sure, I didn't pay for em |
| 00:50:06 | Russ|werk | I was going to use lart, but couldn't get ahold of the flash, so I did a redesign using TSOP flash |
| 00:50:17 | Russ|werk | maybe one day the credit lart will finally come out |
| 00:51:04 | moritz_ | i see. thx |
| 00:53:01 | pmisfit | Russ|werk: nothing significant. just keeping track of my configuration changes. |
| 00:53:38 | Russ|werk | nothing that should go into the tux patches? |
| 00:54:15 | pmisfit | Russ|werk: well, i patched rts_handler to use spin_lock instead of spin_lock_irqsave, in an attempt to fix a hang at bootup. |
| 00:54:40 | Russ|werk | ah |
| 00:54:47 | pmisfit | Russ|werk: but i ended up that driver out completely, and haven't needed to test whether it helped or not. |
| 00:54:58 | Russ|werk | I haven't touched the wheaties/serial flash stuf |
| 00:55:00 | Russ|werk | er stuff |
| 00:55:53 | pmisfit | Russ|werk: yeah. i am curious, though. is it kosher to use the _irqsave versions of the functions from an interrupt handler? |
| 00:56:08 | Russ|werk | dunno |
| 00:56:15 | pmisfit | Russ|werk: er, *in* an interrupt handler |
| 00:56:15 | Russ|werk | read rusties guides |
| 00:56:30 | pmisfit | Russ|werk: rusties guides? |
| 00:57:17 | pmisfit | fires up google |
| 00:59:37 | Russ|werk | http://netfilter.samba.org/unreliable-guides/ |
| 00:59:56 | Russ|werk | see the unsutible for children section |
| 01:01:03 | moritz_ | bye |
| 01:10:32 | pmisfit | Russ|werk: thanks! i'm up to chapter 13 in allessadro rubini's book, but this is a much quicker read. |
| 01:27:29 | pmisfit | Russ|werk: thanks. gotta run. if there isn't a sysctl/proc interface to enable 5v pcmcia, i'll add it in and submit the patch. |
| 01:27:36 | pmisfit | cheers! |
| 02:50:42 | fontenot | damn |
| 02:56:04 | fontenot | hi andersee |
| 03:11:47 | fontenot | not a very flattering article |
| 03:41:44 | andersee | fontenot: hi |
| 03:41:49 | andersee | fontenot: what article? |
| 04:01:31 | fontenot | andersee: the article about lineo |
| 04:01:42 | fontenot | linked from slashdot |
| 04:02:01 | fontenot | does not pain a pretty picture of the company's financial management |
| 04:12:25 | andersee | Nope. I'm glad I don't work there anymore. Sounds like things have only gotten worse |
| 04:23:12 | Morn | is away: sleeping |
| 06:02:40 | | hmmm... i am a Micro$oft minion lurking on this channel in the hopes of obtaining innovative technology to add to the next Windoz release. |
| 06:02:40 | TomW | ibot: ibot? |
| 06:02:50 | TomW | heh |
| 06:03:56 | | andersee was last seen on #tuxscreen 1 hours, 51 minutes and 31 seconds ago, saying: Nope. I'm glad I don't work there anymore. Sounds like things have only gotten worse [Sat Apr 6 05:12:25 2002] |
| 06:03:56 | TomW | ibot: seen andersee? |
| 06:05:05 | TomW | andersee: Erik, any reason why I shouldn't use the cvs buildroot from abt a week ago? I saw you & BZFlag doing a bunch of stuff a few nights ago. Should I go with the latest? |
| 06:06:04 | andersee | sure. The latest and greatest is pretty nice at the moment. Very clean. |
| 06:06:16 | TomW | tnx |
| 06:06:56 | TomW | c++ & threads okay? |
| 06:07:33 | andersee | Threads are fine. For C++ you will need to build a full gcc/g++ toolchain vs uClibc to get libstdc++ |
| 06:07:41 | TomW | k |
| 06:08:12 | andersee | I have source + a build script for gcc 3.0.4 at http://codepoet.org/toolchain/ |
| 06:08:48 | TomW | time for me to get serious with the Tux and stop messing with DRAM stuff. |
| 06:09:33 | andersee | hehe |
| 06:10:58 | TomW | Now that I have enough room to put tiny-x on, I will have to start bugging jacques with questions on getting it working. I just gave his instructions a quick run-through and failed miserably. |
| 06:11:08 | andersee | Hmm. |
| 06:11:13 | andersee | How did it choke? |
| 06:11:20 | TomW | I still would like to put that notebook 10G drive on my 64M tux. |
| 06:11:37 | andersee | I think we need to create a make/tinyx.mk file |
| 06:12:12 | andersee | I plugged a 640 MB Magneto Optical drive into mine one via an Adaptec1460 |
| 06:12:22 | andersee | s/one/once/ |
| 06:12:30 | TomW | I'll let you know abt tiny-x when I try later. I had to fix a broken NT box today. Darned HP printer driver screwed Service Pak 6. :-P |
| 06:13:06 | TomW | I am looking at using J602 and keeping the drive + electronics inside the Tux. |
| 06:13:20 | andersee | J602? |
| 06:14:32 | TomW | Yes, the blank connector on the CPU board. It is memory mapped 8 bit I/O. There is only one register on an IDE interface that is defined as 16bit only. But, that is not such a big deal to interface to via 8 bit. |
| 06:15:51 | andersee | Very cool. I have a spare 3 GB laptop hard drives I'd love to intergrate with mine. |
| 06:16:59 | TomW | It may be that I have to take my dremel an slice off one of the mounting tabs of the speakerphone speaker as it interferes with the connector on the drive. |
| 06:17:20 | TomW | hack, hack, hack... |
| 06:18:19 | TomW | Ok, time to pull from cvs and start merging stuff together. later. |
| 06:21:02 | andersee | latr |
| 06:22:02 | fontenot | hmm just missed him |
| 06:23:04 | fontenot | wonder what problems he had with tinyx |
| 06:27:31 | TomW | fontenot: seems like a week ago that I tried it, then got wrapped up with BZFlag & GPSFan's problem(s) with DRAM. I don't recall right now. Erik suggests the latest buildroot-tux is stable, so I am going to start building a new development environ from scratch. I'll let you know how tinyx goes. |
| 06:28:07 | TomW | fontenot: first, I am going after a "wart" that cost me a few hours in blob. |
| 07:18:32 | fontenot | TomW: ok, let me know if you have issues when trying to build X |
| 07:19:28 | TomW | fontenot: thanks. I will document the steps I took so that we can use it to check your wiki doc, just in case. |
| 07:20:08 | fontenot | TomW: yeah, the wiki doc may already be getting out of date |
| 07:20:19 | fontenot | changes in uclibc have made a couple of the steps unnecessary |
| 07:20:47 | fontenot | once wchar (wide char) support gets into uclibc, things will get much easier |
| 07:21:37 | fontenot | i have found that the latest xfree cvs builds just fine but they totally screwed up the touchscreen code |
| 07:22:01 | fontenot | so I am having to use an older X server from 10-10-01 cvs along with the patch on the wiki |
| 07:22:21 | fontenot | the x server does not depend on any X libraries, so mixing and matching is not a problem |
| 07:22:56 | TomW | Yes, andersee has already done some of the doc'ed changes. |
| 07:23:11 | fontenot | though I cant think of a reason to not just use the 10-10-01 libs as well as the server |
| 07:24:32 | fontenot | it's not *that* old :-) |
| 09:02:03 | halloall | how can i buy tuxscreen in China? |
| 09:03:04 | halloall | why i'm blocked to tuxscreen.net,in fact the usw-pr-web.sf.net site? |
| 09:03:25 | halloall | anybody can answer my question? |
| 09:04:25 | moritz^ | maybe because your government blocks some web addresses? |
| 09:04:59 | halloall | i guess so,but this is the only one that i freqent. |
| 09:05:21 | halloall | the router outside china never response. |
| 09:05:26 | moritz^ | and as far as i know you can buy the tuxscreen if you live in china, you just have to check if your gov allows it |
| 09:05:42 | halloall | how can i buy one? |
| 09:05:56 | halloall | if the sf web site has some mirror? |
| 09:06:01 | moritz^ | http://tuxscreen.net/wiki/view/Users/TimRiker |
| 09:06:15 | moritz^ | or message Tim Riker here in irc |
| 09:06:22 | halloall | i have mailed to him today. |
| 09:06:35 | moritz^ | so just wait for his response |
| 09:06:37 | halloall | i'm waiting for his answer now. |
| 09:07:05 | moritz^ | hey, do you know some german? |
| 09:07:16 | halloall | is there any mirror to the sf site? |
| 09:07:23 | moritz^ | i don't think so |
| 09:07:29 | halloall | sorry,i don't know german. |
| 09:07:44 | moritz^ | ic. was just curious coz of your name |
| 09:08:07 | halloall | it's more of a latin american name. |
| 09:09:20 | halloall | how many debug means does tuxscreen support? |
| 09:10:49 | LoneTech | depends on how much effort you want to put into it |
| 09:11:11 | LoneTech | it has JTAG, so you can pretty much go in at hardware level if you want. |
| 09:11:49 | halloall | very good one.it's much like a development kits than mature products. |
| 09:12:15 | halloall | is the linux on it mature enough? |
| 09:13:15 | LoneTech | mature enough for what? |
| 09:13:50 | LoneTech | it's a linux/arm system, the limitations I know of are from hardware |
| 09:14:00 | halloall | i mean mature to boot and run many app. |
| 09:14:06 | LoneTech | yes. |
| 09:14:18 | halloall | then it's OK to play with it. |
| 09:14:20 | LoneTech | but the arm platform is picky |
| 09:14:27 | LoneTech | so be prepared for some programs that compile but don't run. |
| 09:14:34 | halloall | why? |
| 09:14:50 | LoneTech | many programs have never been tested on more than x86 and perhaps sparc |
| 09:14:57 | halloall | i'm just musing to move to ARM core now. |
| 09:15:04 | LoneTech | arm is much more strict on issues like alignment |
| 09:15:27 | halloall | oh,why arm should be so strict? |
| 09:15:39 | LoneTech | because it's easier to do in hardware |
| 09:15:53 | halloall | a strict RISC design? |
| 09:15:56 | LoneTech | it's part of why it can run on so little power (and therefore produce very little heat) |
| 09:16:23 | halloall | i'm forced to use ARM as many customers here want ARM in their core. |
| 09:16:34 | LoneTech | it is good imho |
| 09:16:41 | halloall | but i know nothing about it b4. |
| 09:17:03 | halloall | To broaden my options in design,i have to study ARM now. |
| 09:17:29 | halloall | but i guess it'll not more complex than the Intel's ugly ones. |
| 09:17:44 | halloall | in fact i like 68k most. |
| 09:18:10 | halloall | 68k is too orthogonal to programmers. |
| 09:18:11 | LoneTech | well, x86 is a horrible mess from the beginning. |
| 09:18:33 | LoneTech | I haven't worked in low level much.. |
| 09:18:56 | LoneTech | but for embedded systems, I'd probably look for mips, ppc, sparc, arm or m68k based platforms. |
| 09:19:00 | halloall | then the only difficulty in ARM is mostly in alignment problem? |
| 09:19:20 | LoneTech | I don't know the details well, sorry |
| 09:19:42 | halloall | whatever,thank you very much. |
| 09:20:06 | LoneTech | mips and sparc, iirc, are standards |
| 09:20:23 | LoneTech | they have the advantage that there are both free cores and multiple manufacturers. |
| 09:20:33 | halloall | i never use or see an embedded sparc by now. |
| 09:21:07 | LoneTech | Epson and Olympus cameras, for instance, use SPARClite processors. |
| 09:21:18 | halloall | and i guess ARM,x86 and 68k is enough for me now. |
| 09:21:19 | LoneTech | iirc, some calculators do too |
| 09:22:22 | halloall | it's said that ARM will be 8051 in 32 bit embedded mcu. |
| 09:22:43 | halloall | Many guys recommend it to me. |
| 09:23:20 | halloall | if Intel's ARM generally much cheaper than other licensees? |
| 09:23:31 | LoneTech | http://www.opencores.org/cores/or1k-new/ |
| 09:23:37 | LoneTech | don't know |
| 09:25:55 | LoneTech | MIPS core: http://www.opencores.org/projects/yellowstar/ |
| 09:34:28 | halloall | is there any virture machine targeted at ARM and hosted on Intel x86? |
| 09:35:02 | halloall | a virture machine with functionality near VMWare. |
| 09:35:55 | LoneTech | you mean an ARM emulator or simlator? |
| 09:35:59 | LoneTech | simulator |
| 09:36:03 | LoneTech | I'm not sure |
| 09:37:02 | LoneTech | probably, but I don't know of them. |
| 09:37:56 | LoneTech | maybe something at http://www.pcasolutionscatalog.com/m_hw.htm |
| 09:38:03 | halloall | one more powerful than normal s/w simulator. |
| 09:38:41 | halloall | one that can simulate int and peripherials. |
| 09:44:13 | halloall | intel has no simulators to ARM.maybe i should insist on gdb simulator before i can get one real boards. |
| 09:44:40 | halloall | but i'm not sure when will i get one. |
| 09:45:10 | halloall | i'll be annoying to be too late. |
| 09:45:39 | halloall | i have tried some app coding in C, |
| 09:45:49 | halloall | and it runs well on gdb sim. |
| 09:46:21 | halloall | but i'm not sure they will especially hearing now that ARM is |
| 09:46:52 | halloall | notorious for runing well in simulator but fail on real h/w. |
| 09:48:09 | LoneTech | there is no substitute for testing. |
| 13:50:32 | fontenot | hi GPSFan |
| 13:51:34 | | hi, GPSFan |
| 13:51:34 | GPSFan | hi |
| 13:51:52 | GPSFan | hibot! |
| 14:19:20 | fontenot | i forget - is strongarm big-endian? |
| 15:26:56 | scanline | is back (gone 18:38:22) |
| 17:18:20 | | GoRK was last seen on #tuxscreen 109 days, 15 hours, 20 minutes and 22 seconds ago, saying: hmm it used to be there [Tue Dec 18 01:57:58 2001] |
| 17:18:20 | scanline | ibot: seen GoRK? |
| 18:23:37 | TomW | stretches & blinks... |
| 18:23:51 | TomW | morning all. |
| 18:24:15 | GPSFan | morning TomW |
| 18:25:17 | TomW | GPSFan: hey, gm. I have been tinkering with the blob sources and the assembly language. Pretty bizzare stuff that ARM assembler.. |
| 18:26:29 | TomW | pretty cool actually, I like the idea of learning another assembly language.. |
| 18:26:30 | GPSFan | gotta run this by you to see if it makes sense, I found that there are 16 chips inside my SODIMM, and they are 28 pin devices, that leads me to believe that they are 2M x 8 parts. |
| 18:26:56 | TomW | is there any part number on those chips? |
| 18:27:41 | TomW | I think that you said |
| 18:27:48 | GPSFan | no, the chips them selves are flip chi chip on flex, (if that makes sense, I'll put up some pix. |
| 18:27:54 | TomW | ... there were chips stacked on top of chips? |
| 18:28:07 | GPSFan | yep, stacked 2 high. |
| 18:28:12 | TomW | hah! |
| 18:28:43 | TomW | Wonder what tiny factory / garage they came out of? |
| 18:28:49 | GPSFan | the label on the module says assembled in japan from korean parts |
| 18:29:04 | GPSFan | there is also a Hitachi logo on the pcb. |
| 18:29:07 | TomW | :-) ... maybe |
| 18:29:51 | GPSFan | I looked at Samsung & Hyundai 2M x 8 EDO's and thay are all 2k or 4k refresh. |
| 18:30:13 | TomW | Well, we did nail down the fact that they were 8K refresh and that the only way for you to use them was to swap the signal lines for RAS, CAS, etc. |
| 18:30:29 | GPSFan | also old parts 16Mbit generation no longer recomended for new designs. |
| 18:30:56 | TomW | All EDO is "not recommended for new design". |
| 18:32:00 | GPSFan | do you know a way of checking the 1M chunks to see if there is really only 512k there? |
| 18:32:55 | TomW | .. From what I have heard, there are small factories around the asian-pacific rim where they have purchased the dies to make discontinued chips, you have an sodimm made by one of these guy's brother-in-law (or something). |
| 18:33:36 | GPSFan | could be, the date code on the module is 1997 |
| 18:33:59 | TomW | GPSFan: that was what I was doing, rewriting portions of blob to see if a 1Meg chunk actually had 1Meg in it. |
| 18:34:36 | GPSFan | like these guys: http://www.gigaram.com/ |
| 18:34:48 | TomW | The 32M'ers I got from Coast-to-Coast Memory work fine, I now have a full 64 Meg Tux! |
| 18:35:34 | GPSFan | you missed my congratulations soon after you posted your results to the mail-list. |
| 18:35:45 | TomW | tnx. |
| 18:36:13 | GPSFan | I read through the blob sourrce, and that sounds like a good idea. |
| 18:36:50 | TomW | Two files are key: memory.c & testmem.S. BUT, testmem is also called by start-sa1100.S. |
| 18:37:19 | GPSFan | when blob finds a larger chunk, will you allso verify it has all it's bits too? |
| 18:38:08 | TomW | no, that is an exhaustive ram test. You know, one thing that I could not figure out (yet) is why chkmem command locks up. |
| 18:38:29 | TomW | Maybe I should look at that instead of memory.c? |
| 18:38:35 | GPSFan | from what I could fogure out testmem just tests the location that it is called with, it is up to the calling prog to go through all the locations. |
| 18:38:52 | TomW | you are correct. |
| 18:39:20 | TomW | What has me confused is the use of the ldmia & stmia instructions. |
| 18:39:42 | TomW | I don't know why they just didn't use ldm & stm. |
| 18:39:50 | GPSFan | where does checkmem come from? is it in blob or an application? |
| 18:40:20 | TomW | checkmem.c |
| 18:40:38 | TomW | it is part of blob-2.0.5-pre3 |
| 18:41:04 | GPSFan | found it, it's in 2.0.5 pre-2 also |
| 18:41:31 | TomW | BZFlag gave me this to config blob: ./configure \ |
| 18:41:31 | TomW | --with-linux-prefix=/home/tom/TuxScreen/buildroot-tux/build/linux \ |
| 18:41:31 | TomW | --enable-maintainer-mode \ |
| 18:41:31 | TomW | --enable-clock-scaling \ |
| 18:41:31 | TomW | --enable-memtest \ |
| 18:41:32 | TomW | --enable-debug \ |
| 18:41:34 | TomW | --enable-lcd \ |
| 18:41:36 | TomW | --enable-jffs2 \ |
| 18:41:38 | TomW | --with-board=shannon \ |
| 18:41:40 | TomW | --enable-all-features \ |
| 18:41:42 | TomW | arm-linux \ |
| 18:41:54 | TomW | I think you need the "--enable-memtest" option. |
| 18:42:52 | GPSFan | ah, I'll look at themakefile, maybe fiddle around with it after lunch. |
| 18:42:54 | TomW | look at my makefile (dcc) |
| 18:43:21 | GPSFan | your "trick" to get your on board 32M is interesting, how did you figure it out? |
| 18:44:18 | TomW | I had been designing with that DRAM a year ago and I remember the missing pins. It was a bit of a mental stretch to "see" the solution. |
| 18:45:50 | TomW | Actually, it wasn't my trick at all, there was an earlier post to the list about it. Except, he didn't go as far as I did in tracking down the easiest way to get the correct signals to the devices, nor did he document what he did. |
| 18:46:19 | GPSFan | post here on #tuxscreen? |
| 18:46:55 | TomW | I don't like to do things that "just work", I want to understand how they work before I accept a hardware change. No, on the list-server: tuxscreen list. |
| 18:47:44 | TomW | Too many times I have been bitten in the butt by a quick-fix. |
| 18:48:27 | GPSFan | I'll have to go back through the archives and look. the memory issue has been with us a long time. |
| 18:48:57 | GPSFan | amen, quick fixes have a way of biteing the hand that solders them. ;>) |
| 18:49:03 | TomW | Did you hear that I will be teaching a beginners class on linux at the local VoTech (adult education). |
| 18:49:04 | TomW | ? |
| 18:49:18 | GPSFan | yep, where are you located? |
| 18:49:30 | TomW | NorthEastern PA. |
| 18:49:44 | GPSFan | near Allentown? |
| 18:49:54 | TomW | Stroudsburg. |
| 18:50:12 | TomW | Delaware Water Gap. |
| 18:50:28 | GPSFan | ah, I used to live in Somerville NJ, I hang out in the western part of the state. |
| 18:50:42 | GPSFan | s/I/and |
| 18:50:45 | TomW | Cool! I grew up in Sussex County. |
| 18:51:10 | GPSFan | small world. I used to work for RCA in Somerville. |
| 18:51:26 | TomW | ... then when I discovered I lived in NJ I made plans to leave! ;-) |
| 18:51:50 | TomW | Farm boy.. |
| 18:51:59 | GPSFan | the western part iwasn't bad then, don't know about know, I left a while ago. |
| 18:52:17 | GPSFan | I am now. Western Colorado. |
| 18:52:25 | TomW | Yeah, I grew up on a 128 acres dairy farm, it was cool. |
| 18:53:04 | TomW | Only thing I know about Colorado is Boulder & Denver. |
| 18:53:06 | GPSFan | off to lunch, my typeing is in need of refreshment. ;>) bbl |
| 18:53:13 | TomW | later. |
| 19:12:13 | GPSFan | TomW: back, could you try the DCC send again |
| 19:13:07 | TomW | here it is |
| 19:14:04 | GPSFan | TomW: my irc client is refusing it: DCC Send from TomW rejected (blob.mk, file type ignored) ????? |
| 19:14:17 | TomW | let me tar it. |
| 19:14:22 | GPSFan | k |
| 19:16:19 | TomW | try this one |
| 19:16:44 | GPSFan | ;>( DCC Send from TomW rejected (foo.tar, file type ignored) |
| 19:16:57 | TomW | what client? |
| 19:17:14 | GPSFan | maybe I have something set incorrectly Win98 mIRC |
| 19:17:37 | TomW | HAH! you are having a "Micro$oft moment..." |
| 19:17:53 | GPSFan | it's happened before, ;>) |
| 19:18:09 | GPSFan | time to rtfm again. |
| 19:20:14 | GPSFan | TomW: try again please |
| 19:20:46 | TomW | sending |
| 19:21:01 | TomW | looks like you got it. |
| 19:21:20 | GPSFan | got it, probably my fault, I had the default set to ignore rather than ask. |
| 19:23:35 | GPSFan | TomW: looks like you are building from the 2.0.4 sources: BLOB_SOURCE:=blob-2.0.4.tar.gz |
| 19:24:04 | TomW | You should attend my class. ;-) one of the first things I will teach them is how to install linux on a machine with windoze on it so that it will dual-boot. |
| 19:24:52 | TomW | ok, forget that. it was a hack. I stuck the 2.0.5-pre3 cvs image into that dir. That makefile is from the TuxScreen makes. |
| 19:25:04 | TomW | I hacked it to work with the cvs copy. |
| 19:25:14 | TomW | look at the rules. |
| 19:25:28 | TomW | s/rules/other rules/ |
| 19:26:25 | TomW | I wasn't about to build a makefile that pulled from cvs. |
| 19:28:24 | GPSFan | your class, that is, I don't know nearly enough about Linux. |
| 19:29:56 | TomW | HA! nor do I, I have been working at it steadily, and in earnest, for four years now. I still keep learning a lot of new stuff! |
| 19:31:17 | GPSFan | my history with Linux goes back 6-7 months. been around unix for a much longer time, but never for developing. |
| 19:31:47 | TomW | I have abt 24 years of writing code. |
| 19:32:37 | TomW | The GNU development environment is like the most development environs I have ever used, but on Steroids! |
| 19:32:56 | TomW | s/the// |
| 19:33:21 | TomW | Do you get puzzled by stuff like: s/the// ? |
| 19:34:25 | GPSFan | no, I'm a hardware, not a sowtware, type. only wrote code when neccessary to test something out. |
| 19:36:39 | TomW | yeah. I started reparing hardware as a line tech back in the late 70's. I worked for A & M Varityper and Vydec at the time. We (us techs) had access to the control boards for a Photo Offset printer. The thing was powered by a Z80 processor and had a CRT. We would get the scrap boards and built our own personal computers. |
| 19:37:29 | TomW | .. Then we would get boards for the guys up in Software Engineering so they could build their own machines. We gave them hardware in return for software. They had CP/M |
| 19:38:20 | GPSFan | cool, when I was at RCA we used 1802's and I scrounged 4K DRAMS for our Z80 personal computers. I ran CP/M too, later CP/M 68K |
| 19:38:33 | TomW | That's when I got involved with the whole free software community stuff. We didn't pay for software back then, we each took what the other had, improved it, and shared the result. |
| 19:38:47 | TomW | the Cosmic VIP |
| 19:39:10 | GPSFan | COS-MAC |
| 19:39:34 | GPSFan | 1802 was very rad-hard. nice for space apps. |
| 19:39:49 | TomW | something like that. IIRC, that was a single chip solution, you didn't need an external clock chip, etc. |
| 19:40:30 | GPSFan | correct, the 1801 was a 2 chip set. neither had a stack, man what a pain to do subroutines. |
| 19:41:50 | GPSFan | very low power too, one customer built a handheld "terminal" that had no on/off switch. ran forever on a Lithium primary battery. |
| 19:47:07 | GPSFan | TomW: chkmem looks like the right tool to verify memory areas, it also looks like it may have been imported without too many mods, I wonder if it ever worked on LART? |
| 19:50:04 | TomW | just building from the latest CVS of buildroot-tux... |
| 19:56:48 | GPSFan | bbl, off to fix the tractor. ;>) |
| 22:44:37 | Morn | is away: chillin' |
