IBM's 386 Tower IBM's 386 Tower of Power: The PS/2 Model 80of Power: The PS/2 Model 80

With a 32-bit Micro Channel bus and room for six drives IBM aimed this tower directly at the likes of Compaq. But what’s inside this monstrous machine and how can it be upgraded? And what can you do with an old boat anchor like this? Join me as I pull this PC apart to see what you got when you bought a $6,845 workstation in 1990.
