[Simh] VAX 8200

[Tim Stark]

Yeah. Yes, it need console media for SRM firmware.  There is 16k EEPROM in VAX 8200 contains config setting and bootstrap codes for RX50 and KDA50 drives. 
When power up started, a RX50 bootstrap will be copied into boot RAM at starting 20090000 from 20098000 then execute it.

KA820 technical manual have a listing of boot ROM for RX50 and KDA50.   Does anyone have a copy of EEPROM image? Can someone make a dump of console media disks?

Yes, KA820 supports multi-processor system.

  I have a running 8350 as well, should you need a dump of the console media or something.

  It is, I believe, the physically smallest BI bus VAX, and therefore interesting for those reason.  It's the only such machine that I could fit in my garage :-)

  It's also the only multi-processor VAX system that I have and equally interesting for that reason too.  FWIW, I've always wondered if the limitation to two CPUs was purely for testing and support reasons - it doesn't seem that there's any reason why you could not plug in three or even more CPU cards.
