The TRS-80 was Tandy Corporation's desktop microcomputer model line, sold through Tandy's Radio Shack stores in the late 1970s and early 1980s.

The Model 4P is a portable computer originally retailing for $1799, and is the transportable version of the TRS-80 Model 4. It weighed 26 pounds, the screen was black and white, which later changed to green.

There was only a small boot ROM in the machine, unlike the desktop model 4, which has a basic ROM installed, and unlike other models in the range, there was no cassette interface, as by now disk drives were the norm for portable machines.

A high resolution graphics card could be purchased separately.
