I have a BA11-M box with a backplane that I am sure has been upgraded to
be 22 bit addressing.
When I got this box it had an 11/23 Dual width Cpu, MXV11-AC with custom
boot ROMs and a 256KB MSV11-P memory board. The memory in the MXV11 had
been disabled so I suspect the backplane was upgraded to 22 bit.
What I want to do is put a LSI 11/2 (M7270) and/or LSI 11/03 (M7264)
into this box and construct a minimal, basic PDP11. This system would
have 64kb of memory, some kind of serial interface and an Emulex UC07
running a SCSI disk or SCSI2SD adapter. The OS would be RT11 V5.3.
Can I operate these Cpu's in a 22 bit backplane?
If so, does anyone have spare MSV11-DD 64kb memory and DLV11 type serial
cards for sale/trade?
