Richlb Posted September 25, 2021 Share Posted September 25, 2021 I posted on here a few days ago about setting up a full system I've had in a box for about 20 years. It works! Well, mostly - the data pack drives have gunky wheels which I need to remedy and the printer head sticks to the rubber cylinder a bit. But - what is this board under the cover? I see the AdamLink module, but there is also a translucent board sticking up in there. What is that? Extra memory? Doesn't really look like it. Can't seem to find any info on what it might be.

Tekman Posted September 25, 2021 Share Posted September 25, 2021 64K RAM expander card. I see it has a 41464 DRAM mostly covered by the data drive cables and verifies it's a RAM expander and the IC below (not visible) must be the other 41464 for a total of 64Kx8.

NIAD Posted September 26, 2021 Share Posted September 26, 2021 It’s a 64K Memory Expander and I think it was made by Orphanware Business Systems or is a knockoff of it by a Canadian company. Quote Link to comment Share on other sites More sharing options...
