The Micromint E-Z Color
Micromint sold several products for the TRS‑80 that were based on designs that Steve Ciarcia had presented in his “Ciarcia’s Circuit Cellar“ column in BYTE magazine. The Micromint E-Z Color was a color graphics interface for the TRS‑80 Model I and Model III that was based on his August 1982 column. In addition to the TRS‑80 version, there were also versions of the E-Z Color sold for the S-100 bus and the Apple II.
The TRS‑80 version was available in two configurations:
- “assembled and tested” for $249
- a “complete kit” for $219
Also included with the E-Z Color were connecting cables, power supply, manual, the “Super Editor software”, and an animation demo.
The E-Z Color was based on the Texas Instruments TMS9918A graphics controller, the same chip used by the earlier CHROMAtrs TRS‑80 color graphics add-on. Because the E-Z Color and CHROMAtrs shared the same graphics chip, they also shared many of the same features. These included four video modes, prioritized sprites, and a resolution of 256 by 192 with 16 colors (including transparent). Despite the similarities, there was no software compatibility between the E-Z Color and the CHROMAtrs. Unlike the CHROMAtrs, the TRS‑80 version of the E-Z Color doesn’t seem to have included any joystick or sound support.
The TRS‑80 version of the E-Z Color was advertised only briefly during 1983. Although it looked like an interesting product, I don’t know of any TRS‑80 software that was written to support it.
