The Tandy 1000 Professsional Computer was the first in a line of more or less IBM PC compatible home computer systems produced by the Tandy Corporation for sale in its Radio Shack chain of stores.
The original Tandy 1000 was a large computer almost the size of the IBM PC, though with a plastic case over a steel lower chassis to reduce weight. The original Tandy 1000 featured a proprietary keyboard port (using an 8-pin DIN connector) along with 2 joystick ports (using 6-pin DIN connectors) on the front of the case. The rear featured a digital monitor connector (a standard 9-pin female D-shell compatible with CGA/EGA monitors), an RCA-style composite video-out connector, a single RCA-style monophonic line-level audio connector, a port for a light wand, and a proprietary edge-card connector used to attach a parallel printer. The original Tandy 1000 came standard with one internal 5.25" double density floppy disk drive, with an additional exposed internal bay usable for the installation of a second 5.25" disk drive (available as a kit from Radio Shack). 128k of memory was standard, with the computer accepting up to 640k of total memory with the addition of expansion cards. MS-DOS 2.11 and DeskMate 1.0 were included with the system.
