Hi all, removing some upgrades from my IBM 5150 to revert it to a configuration closer to stock. All of these components were working before I pulled them from the machine unless otherwise listed.
Intel Inboard 386/PC ($1200): comes with 5.25" driver disk, manual, 1MB memory expansion (not working, at least one of the ram chips are bad), and Harrison's 4MB memory expansion replica with SIMMs. 387 FPU is also installed on board.
IBM 5161 Expansion Unit ($1000): Chassis and cards appear to be original, backplane appears to be an accurate replica and cable is likely the one available from Mouser. Chassis is a little beat up with no rust and PSU is noisy and unserviced but works (standard XT form factor PSU). No drives in the 5.25 drive bay slots
Cyrix cx486drx2 25/50 ($200): Clock doubled 386 to 486 upgrade, verified to work on Intel Inboard with 16 MHz external (32 MHz internal) clock. Heatsink appears to be firmly attached but correctly oriented.
Am happy to discuss bundling if someone else wants to experience something close to the maximum performance of the original IBM PC/PC XT architecture.
