T > TANDY RADIO SHACK  > TRS-80 Model 200   


Tandy Radio Shack
TRS-80 Model 200

The Tandy 200 was an evolution of the successful Tandy 100. It offered more RAM and a bigger display. The computer was powered by internal batteries, providing up to 16 hours(!) of use.

A lot of utilities were in ROM: a telecommunication program (telcom) which used the built-in modem, MSPLAN spreadsheet (light version of Multiplan), text editor, calendar, address book and BASIC Programming Language.

3.5" floppy disk drives could be connected via the RS-232. There were actually 2 drives made by Tandy for the Model T computers. The TPDD held 100KB whereas the TPDD2 held 200KB. The TPDD2 could read the TPDD disks. They both used 720k floppies. A video interface was also available, it offered a new display resolution (80 columns X 24 lines) on any external video display unit.

The main competitor of the Tandy 200 was the Epson PX-8. Note that several of the ROM programs were written by Bill Gates himself!
