Tandy Radio Shack 1000 HX

The 1000 HX is one of the Tandy 1000 series of PC clones that were introduced in 1984. The HX had a single 3 1/2" floppy and DOS 2.11 stored in a ROM. It was possible to configure the system to boot from the floppy disk instead of the ROM. Tandy never offered a hard disk for this system, but several aftermarket companies did. Expansion cards for the HX were electrically the same as the ISA bus in and IBM PC, but had a different connector to make them more compact.
