rtVAX 300.

[no-trimming damage repaired manually] It's a long shot, but it might be worth typing in a small test program that uses IPRs 32-35, because if they work you don't need to go through a ROM code trampoline. Here's an example, including assembled binary. (This was hand-assembled; I thought I had a VAX assembler but can't seem to find it. But I checked by disassembling.) movb $'x,r0 90 8f 78 50 movab 9f,sp 9e af 31 5e bsbb 1f 10 06 3: bsbb 2f 10 0f bsbb 1f 10 02 brb 3b 11 fa 1: mfpr $34,r1 db 22 51 tstb r1 95 51 bgeq 1b 18 f9 mtpr r0,$35 da 50 23 rsb 05 2: mfpr $32,r1 db 20 51 tstb r1 95 51 bgeq 2b 18 f9 mfpr $33,r0 db 21 50 rsb 05 .align 4 .space 16 9: The code is PIC, so you can base it anywhere you like. At 0, for example, you might d/l/p 0 50788f90 d/l/p 4 5e31af9e d/l/p 8 0f100610 d/l/p c fa110210 d/l/p 10 955122db d/l/p 14 daf91851 d/l/p 18 db052350 d/l/p 1c 51955120 d/l/p 20 21dbf918 d/l/p 24 00000550 Then start it. My memory of VAX console is fuzzy, but I think that would be something like (again, based at 0) d pc 0 d psl 041f0000 g If MFPR/MTPR console access works, it should print an x and then echo back whatever is typed at it. I haven't been able to test this; none of my VAXen are in runnable shape right now. But I'm moderately sure the code is right; it's pretty simple. Perhaps someone with a KA630 set up to run can test it. On my emulator, it prints the x but nothing more - but, as far as I can tell from reading the code, that emulator doesn't support console input at all, so that's hardly surprising. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
