My system came with one of the last NEAT-based

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.
I used to have one like that, and I may even still have some SIPPs --
but they would be 256K SIPPs, which you probably don't want. However,
you do realise that SIPPs and SIMMs of the same size (capacity) have
exactly the same pinout? You could either tack pins onto SIMMs (I've
seen it done) or fit a SIMM socket to the board, if the spacing between
the SIPPs is standard. I may also have some 1MB DRAM. What pinout and
config does your board need?
