Extended UNIBUS memories
From Computer History Wiki
Extended UNIBUS memory main memory cards for the Extended UNIBUS were available from DEC and from a number of outside vendors.
All DEC EUB memory used DRAMs, and some used ECC to automagically correct single-bit errors, and (at a slight penalty in response time when an error occurs) detect double-bit errors.
DEC
- MS11-L MOS memory - primarily UNIBUS, but had an EUB mode
- MS11-M MOS memory - MS11-MA, -MB models (128, 256 Kbytes)
- MS11-P MOS memory - (1 Mbytes)
