The Model 4 Grafyx Solution

The Model 4 Grafyx Solution was the most popular high-resolution add-on for the TRS‑80 Model 4, and probably the most popular Model 4 add-on in general. It was introduced in 1984 for a price of $199.95 by Micro-Labs, creators of the earlier Model III Grafyx Solution. The Model 4 Grafyx Solution provided true high-resolution access to every pixel on the 640 by 240 Model 4 display, yet was easily user-installable in only a few minutes.

The Model III Grafyx Solution

The Model III Grafyx Solution was a high-resolution graphics add-on for the TRS‑80 Model III. Created by Ted Carter, president of Micro-Labs, the Grafyx Solution was introduced in early 1982 for a price of $299.95. There never was a Model I version of the Grafyx Solution.

The Model III Grafyx Solution used a different approach than 80-GRAFIX, an earlier Micro-Labs product for the Model I and III.

80-GRAFIX

Many people considered the lack of high-resolution graphics to be the biggest deficiency of the TRS‑80 Model I. The maximum resolution of the Model I was 128 by 48 by using block graphics. Many games made good use of that resolution, but it was still low compared to other computers.

The 80-GRAFIX was one of several high-resolution add-ons available for the Model I. Designed by Ted Carter, it was originally sold by Programma International for $149.
