The MRV11-C Read-Only Memory Module was a QBUS ROM card. It held up to sixteen 8-bit x 4K ROM/PROM/EPROM chips; it thus held up to 64KB when fully populated. The entire ROM contents were either directly visible on the QBUS, or through two independent 2KB windows (somewhat like later, larger UNIBUS ROM cards). The MRV11-A was a dual-height card, the M8048.
