The '''MRV11-C Read-Only Memory Module''' was a [[QBUS]] [[Read-only memory|ROM]] card. It held up to sixteen 8-bit x 4K ROM/[[PROM]]/[[EPROM]] [[integrated circuit|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 [[DEC card form factor|dual]]-height card, the '''M8048'''.
