I need to replace some SIMM sockets on an memory/SCSI card, I think I can get away with 4 slots, but ideally I'd replace all 16 slots.
There are various models of 30 pin SIMM sockets, you'll need to find something that physically fits. I have 8 x new dual 30 pin SIMM sockets (16 slots) in stock, which are AMP part number 2-382130-1, compatible with what's used on the Progress Zeus 2040 cards.
