IBM PS/2 Model 55SX

Reviving an IBM PS/2 Model 55SX. We'll go over some PS/2 history, Micro Channel Architecture, and repair the Dallas clock battery on this unit to get it working. We'll try booting DOS 3.3 and 5.0 via floppy disk and go over some Remote Initial Program Load plans to boot this thing over a token ring network in the future.
