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!

I have a Tandy 200 portable computer, with all the manuals, and even the couplers. I bought it in 1988 because I was working as a journalist. I used to to write my stories and send them to the newspaper, using the couplers on pay phones to transmit. Amazing to think about, really.

It was my first laptot. If my memory is good, Reuters or another big news company use it.. In fact, for a copy writer, this computer was the best companion! I baught it in rom 1987 and use it to 89. Excellent Keybaord, full view on sceren and a lot of other stuff... For me the 200 is a classic computer. Default? Yes! External serial fucking floppy driver, fucking extensions..... But...... I'd ll to have it again... My Lifebook from Fujitsu on Windows 2000 is only worst......;
