2020-12-04 Thread Douglas Taylor via cctalk
The boot roms for the MXV11-B multifunction board can be used in the MRV11-D general purpose ROM q-bus board.  Neat if you want to put together a small system. I have a MRV11-C board and it differs from the MRV11-D board primarily in the ROM sockets, 24 pin on the MRV11-C and 28 pin on the MRV
