#LSI11
4 messages in this thread
Does anyone out there have any LSI11– M7264 CPU boards they'd like to
sell. I need ones with fully populated RAM and the Extended Instruction Set
Chip. Also does anyone have the EIS Chips by themselves.
Heres a question is there any way to add a battery backup to memory
for the LSI11. Also does anyone have a Schematic for the M7264 I could get
a copy of.
I have 2- PDP-8A Systems that need a good home( IE: Any place but mine
). If interested or can help me out with the above please reply.
Thanks,

Yes, there is a way to add battery backup to memory for the LSI-11. The
pins are there on the backplane connection. You'd have to look in one of
the old DEC Microcomputer Handbooks for the specifics about which pins and
how to use 'em, though.

Hi Terry,
How are you today. If you would like LSI-11 M7264 modules with the EIS
option, fully tested, these are available for $100 per unit. Let me know
how many you want and we can work something out.

Terry, I have 3 on those cards with the EIS. Please call me at
412-781-3633 and we can discuss you other needs. I think I have a
technical manual for that card and possible some schematics but I am not
sure. I will check this out tomorrow. Joe.
