Have a Radio Shack Computer and don't know what it is?
What Is It
Reprinted from Computer News 80
Because so many are picking up computers now from the used market, we thought that a list of catalog numbers would
be helpful in identifying what computer you have or may have the opportunity to purchase.

We hope that this table will assist you in identifying your computer or one that you may purchase from a school sale or other source. We did not carry the color computers all the way through to the Color III because we felt that if you are a CoCo buff that you should already be familiar with them and they were in the Tandy catalogs from 1987 on, until they
were also discontinued in 1991.
Many changes were made to the internal components of these computers as they were produced, which means that not all computer motherboards, etc. are the same even though the computers may have the same catalog number.
