From the project

PS2 to Tandy 1000 Keyboard Adapter

This is a simple in-line adapter to allow use of more modern PS2 Keyboards on early Tandy 1000 computers. This adapter works on 1000, 1000A, 1000HD, 1000SX, and 1000TX computers.

This adapter is for the Tandy 1000, 1000A, 1000HD, 1000SX, and 1000TX computers only. It will not work for any other computer model as it is

This adapter simply connects in-line between your PS2 keyboard and the Tandy 1000 computer. Simple plug-and-play.
