The MXV11-A Multifunction Option Module is a QBUS dual-height peripheral board (M8047), intended to allow the creation of complete systems in a minimal-sized QBUS backplane.
It contains two asynchronous serial lines (using the DL11 programming standard), an optional non-programmable line time clock, a block of main memory, and some PROM for bootstrap purposes. The serial lines are connected via 10-pin Berg connector headers on the top edge of the card, using the standard DEC asynchronous serial line pinout, and line 1 can be set to halt or boot the machine on a break.
Two different versions exist:
- MXV11-AA - 8Kbytes of RAM
- MXV11-AC - 32Kbytes of RAM
It is a Q18 device, and the RAM cannot be used when it is in a Q22 system.
