Hi all, See... now I remember why I should not dive into yet another restoration project (such as my AT). It only causes me to need even MORE stuff :) My system came with one of the last NEAT-based mainboard, which did support both the 1Mbit DRAM chips, as well as those funky "SIPP" modules. It had 2 banks of those chips installed, and, at the time, I also had two banks of SIPPs in it, for a total of 4MB. For some reason, the SIPPs have been pulled, so I am now looking for a bunch of either SIPP modules, and/or about 18 of the 1Mbit chips to "fill the board." A 80286-12 copro would be fun, too. If anyone has something laying around they'd part with, pse contact me off-list !
