Vintage Computer TRS-80 Model 1 Expansion Box Radio Shack: $51
This sale is for the Expansion Interface only. No Model 1 is included in this sale. This is a Vintage Computer item being sold "as-is" - you will need to locate whatever ribbon cables it requires to talk to a Model 1. This box should greatly expand the capabilities of the stock/standard TRS-80 Model 1 microcomputer from the early 1980's. Great fun for Vintage computer collectors.
