Oo what a shameless plug, resurrecting my thread from years ago.

I did actually find the Zip chips that I needed - and I should point out that you
don't have the chips I was looking for - I was looking for the MN41464AZ08 chips which are used for the dual port RAM, not the 514400 chips which you have for the main RAM. But as most people will be looking for normal RAM, not dual port RAM, your plug is allowed.

Never did get that bloomin' bridgeboard working. Real shame, given it's one of the very few 486SLC-based A2386SXs....
