RM PC386
A 386SX PC that featured IBM's own ill-fated interconnect architecture - MicroChannel. In a Betamax v.VHS style war MCA was up against new kid on the block PCI, but PCI had more backers and MCA was consigned to history.
This machine here was one of the few to be produced with MicroChannel slots and expansion cards. It's a 16mhz 386SX based machine with a 40mb hard drive, dedicated ethernet board and proprietary memory cards. It's also built in a most bizarre manner, in that to get access to the motherboard and hard drive you take the top off, remove the floppy drive and unclip the power cable, then take the bottom of the case off and pull the board away from the internals! Weird.
