Tandy Radio Shack
TRS 80 PC-2

After the success of the TRS-80 Pocket Computer (a.k.a. TRS-80 PC-1), Sharp also manufactured their PC-1500 (see there for more technical information) in a version for Tandy Radio Shack.

This machine was marketed as the TRS-80 PC-2 (catalog number 26-3601). Internally, it was exactly the same machine. Only the front face design had been changed: the keyboard layout was different, with an additional enter key, and the display had been shifted to the right. Moreover, the colour style was also slightly different, with a light gray instead of brown back of the case.

Some peripherals supplied by Tandy were the "docking station" with 4 colour pen plotter and cassette interface (catalog number 26-3605), 4 and 8 KB RAM module (26-3615 and 26-3616), an external tape interface (26-3605) and an RS-232 interface (26-3612). Of course, all peripherals developed for the Sharp PC-1500 could also be used.

Thanks to Roman von Wartburg and his site for information and picture.



I just unearthed a Tandy PC-2 that belonged to my brother, and just for kicks I googled it to see what would pop up. What I don''t understand is of all the photos I saw that were purported to be of a PC-2, none of them look like mine nor are they identified as being a PC-2 on the face of the unit, including the ones shown on this page. What''s up with that?

I have a PC-2 and it still works 30 years later. Only the pens in the printer/cassette interface are dried out and don''t work, but I have refilled them before using a water-based ink. I also have the 4K memory module for a total of 6K. The computer uses Basic and I can pack a lot of programming into that amount of memory.
