Although it was basically the same CP/M machine, it had several notable enhancements. The all-in-one case had an innovative design. The main unit and mass storage devices were mounted vertically at the right side of a large tilting 14" green display (at the time the standard size was of 12"). The keyboard was also greatly improved. It offered 16 programmable function keys and 10 pre-programmed text-editing keys. It was one of the first keyboard to offer a built-in wrist rest.\ The TS-803 was also one of the rare CP/M machines to run graphics. At the same period, Televideo also released the **TS-1603**, an Intel 8088 version with same design which ran CPM/86 and MS-DOS OSs. --- TS803s network by **VB Woodfield**:\ The accounting office I worked for in the late 80's used 5 TS803's connected to a single Televideo external 40MB Winchester belt driven harddrive with built in tape drive.\ The case was roughly the same size as the TS803 and could connect to 8(?) TS803s. It came with the standard CP/M and an optional enhanced CP/M OS you loaded via the tape drive and provided commands via the TS803 connected to the first network plug. I believe there was a dip you moved on the TS803 to toggle this function.\ The TS803 had a non standard pinned serial port to attach a direct printer or mouse and an special connection for the network "server"\ Televideo also used a proprietary format on it's 5 1/4 floppy drives.\ The system disks included quite a good demo of the graphics capability in the form of a sales pitch for Televideo. Movie star by **Ernest**:\ The Televideo TS-803 was used in the Library scene of the movie "Pretty in Pink," and as usual for Hollywood movies, the computer was shown to do impossible things (for that time.) In particular, the computers were networked together like modern ethernet office computers, and the video images were impressive even by today's standards (ie, impossible for the day.)
