RAM 'B/64' - 64K DRAM Memory Card
Why the original RAM 'B' card was only equipped with 48K is something of a mystery. Gemini produced a 64K card as one their first products which was fully compatible with page mode. Being a similar price it was fairly obvious which would be the card of choice.
Eventually a professionally produced 16K upgrade add on was produced to give a full 64K. Little information exists as to who produced this device but the first one I encountered was in a factory built Nascom 3. This suggests it was an officially approved product upgrade.
