AlphaMicro Systems AM1000, AM1200, & maybe AM100L drive replacement

here is the command reference for 2.3A, let me know if that meets your definition of "broken"

Here's what I have for AMOSL... (BAD indicates lots of missing pages in the PDF)

 

[curbie]

where did you get those?
50% bad also, means 50% good, which is way better than nothing.

I found better copies of everything on the internet archive.

I'll create a shareable google drive... I've replaced all the critical stuff with 100% good copies and finding more stuff.

 

[jubjub07]

Not from Bitsavers as far as I can tell - Bitsavers has a lot of AM100 stuff, but nothing new (that I could find, could be mistaken) - I've looked there before. Maybe we should post all this new stuff up there.

I'm mainly looking for AMOSL 1.3 and newer...

the "Bad" versions I found were on manuzilla.com... the internet archive credits the same site with *most* of what I've found, but they're good versions. I suspect that the Manualzilla software is dropping pages for some reason, when rendering the pdfs, but the archive has a pdf version with all the pages.

Here's the search I did on Internet Archive that turned up a lot of stuff: https://archive.org/search.php?query=AMOS+Monitor+Calls&sin=TXT

Here's what I downloaded so far:

jubjub07, I responded to your E-mail.

That one looks good. The ones I downloaded from Manualzilla had random missing pages (I'd guess 20% or more). Thanks.

I found a LOT of manuals in the internet archive that are all good. Still missing the Assembler manual and instruction set manual from the 680x0 era... which seems weird, but I do have the AlphaBasic and AlphaBasic Plus manuals in good order.

don't know what you're after, but i can give you a list of all supported assembler instructions and directives, wrote a dis-assembler back in the day. let me know, i'll zip something up for you.

 

[jubjub07]

There’s reference to the AMOS instruction set manual, but haven’t found it on line. I did find the Assembly Language Programmer’s manual. I also found a pdf of a book on the 680x0 instruction set by Bob Fowler and Stan Kelly-Bootle, 2 old AM fans… so I’m sure I can manage. IIRC the AMs have some quirks that might be good to know about in the instruction set guide…

Well, I finally dug out the AM-1000 I had floating around the house to try this and it's not acting right (LEDs 81 and 6). I'll have to go into storage for one of the other systems; obviously would prefer not to try this with my Eagles just yet.

 

[jubjub07]

Let me know if you need me to try a different driver or something.

 

[curbie]

that's status display on boot "81" and "6"?

 

[curbie]

Classic,

found both status display codes in the boot prom code:
START: DIAG 6_____;bootstrap checksum error
L5604: DIAG 81____;low memory test

i'd be suspicious of ram, initially. what does self-test say?

[ClassicHasClass]

It won't come up in self-test. I think there's something more fundamentally wrong with it. It's not been powered up in awhile. I'll figure it out separately.

 

[curbie]

Classic,

I'm a big believer in pulling all socked chips, removing any oxidization with an eraser, and to help kill further oxidization silicone greasing the pins, next spraying the socket pin holes with CRC, then reinserting the cleaned chips back into there original sockets. Time and oxidization can block signals, of a once running system.

Little status update:
1. AM1400 running great with the SCSI->SD 5.0 card...
2. I ordered another card from the inertial computing - they're newest ZULU 1.1 board that is the next generation SCSI->SD... I hope to use it to get the AM1200 up and running.
3. I popped the Boot Proms out of the AM1400 and copied them to disk, so I have them backed up.
4. While they were out, i tried them in the AM1200, to see if they'd boot the SCSI2SD, but only got an "FF" on the status. No self-test, nada.
5. I noted that the AM1400 PROMs are AMD2764, while the AM1200s are AMD27C64...
6. I was unable to read the AM1200 Proms in my prom reader... kept getting a chip ID error. I'd like to back them up, and will try again when I have more time.
7. I ordered some 2764 blank proms to make copies of everything.

I'm assuming at this point that the am1200 won't run on Am1400 Proms... so if you have saved prom files for the 1200 that would boot a SCSI2SD drive, I'd love to try 'em!

the only thing i can think, is to send me an email simply stating to resend it. that should flip their spam flag on my addy.

Will do
