| 06:59.04 | T0mW | no "l6:6:shutdown:<cmd>" ? |
| 06:59.16 | T0mW | andersee: in inittab? |
| 06:59.43 | andersee | T0mW: it sends a kill signal, waits a second or two, then runs the specified shutdown commands |
| 07:00.06 | T0mW | andersee: ok, so, busybox doesn't have runlevels, correct? |

| 07:04.45 | T0mW | just putting the touches on the ZipIt build, there is a util to turn power off, but I need to run it on "halt" not rcK |
| 07:06.28 | T0mW | andersee: what you been working at lately? |
| 07:07.16 | andersee | T0mW: of late, mostly on some disk backup stuff |
| 07:07.35 | andersee | T0mW: fairly boring stuff really, but keeps food on the table |
| 07:08.00 | T0mW | andersee: I've been doing mostly cleanup of recent projects. Going to meet with a customer on Thursday to talk about a 1 year commitment: 1099 |
| 07:08.55 | andersee | that should keep you out of trouble |
| 07:09.09 | T0mW | andersee: the big issue for me has been trying to figure out what to charge per hour: ARM MMU work on proprietary system, xlate 8070 assembly source over to ARM asm, design a platform to run the code on... |
| 07:09.34 | T0mW | andersee: the existing asm source is like 500K lines |
| 07:09.45 | andersee | yikes |
| 07:09.57 | T0mW | he has been writing this for 26 years! |

| 07:10.26 | T0mW | yeah |
| 07:10.41 | T0mW | there is a one year drop-dead on the project |
| 07:11.17 | T0mW | andersee: maybe I can get my teeth fixed now? |
| 07:11.20 | andersee | probably best to write an automatic translator |
| 07:11.52 | andersee | doing it all manually would be a beast |
| 07:12.26 | T0mW | andersee: naw, been thinking about it. The old 8070 code is so bastardized that it doesn't translate well. Last time I did this for him (14years ago) I wrote a custom YACC |
| 07:13.10 | T0mW | this time, I am thinking of making the program C-like and make all the ASM instructions C macros |
| 07:14.08 | T0mW | this way, I can mix C into the code system, and be able to use a debugger on the code without having to look at the underlying asm |
| 07:14.23 | T0mW | do source level debug on: |
| 07:14.44 | T0mW | LDA (P2) |
| 07:14.49 | T0mW | instead of: |

| 07:16.07 | T0mW | andersee: I treated the old code as if it were macro assembly |
| 07:16.41 | T0mW | now, I want to do basically the same, but hide it more |
| 07:17.42 | T0mW | andersee: I wish I could, I've tried to rewrite some of his 8070 code into C, he hand optimizes his code. A lot of incestuous code in there |
| 07:17.59 | andersee | ugh |
| 07:18.08 | T0mW | spaghetti city |
| 07:18.36 | T0mW | I gave him an estimate of 3..6 years to rewrite it all in C |
| 07:22.38 | andersee | even so, I personally would try to code up automatic translation to i.e. gimple |
| 07:23.18 | andersee | or RTL |
| 07:23.40 | T0mW | andersee: yeah, I've started on some perl to do the translate / mangling of the file source |
| 07:24.47 | T0mW | andersee: I see in your init source there, that I can patch it to insert my machine shutoff code |

| 07:28.54 | andersee | Object Code Translation Home Page |
| 07:31.24 | T0mW | It would be interesting to look at. However, this guy only writes in 8070 assembly, he knows no other assembler or high level language |
| 07:31.26 | T0mW | :( |
| 07:31.39 | T0mW | so, I have to keep him in the "same source" |
| 07:32.13 | T0mW | andersee: but that is OK! 5 years or 10 years from now, he'll need to do this process all over again! |
| 07:32.55 | andersee | heh |
| 07:33.31 | andersee | you could probably do an auto translation from 8070 asm into java bytecode |
| 07:33.40 | andersee | then use something like: http://linux4u.jinr.ru/usoft/WWW/www_blackdown.org/kbs/jolt.html |
