Original IBM 5170 AT Motherboard - Fully Populated

• Highly collectible, very rare original board
• Fully populated with innovative STACKED 128k DRAM modules (two 4164 DIPs stacked together)
• Intel 80286 processor
• Intel 80287 math coprocessor

Very rare board, probably still in perfect working order, as it was pulled in working condition ~35 years ago and carefully stored since then. Unfortunately, unable to test as I do not have the matching vintage power supply, etc.
