IBM PS/1 Essential Tower (Machine Type 2168): 486DX2-50 with Mwave, DOS 6.22 and Windows for Workgroups 3.11

A classic IBM PS/1 Essential tower, cleaned up, serviced, and ready to use. It boots into DOS 6.22 and Windows for Workgroups 3.11, sound is working in both DOS and Windows, and all three drives (5.25\" floppy, 3.5\" floppy, and CD-ROM) have been tested with real software. With seven open 16-bit ISA slots and two open memory slots, there\'s plenty of room to build on.
