Mikrokolor Color Graphics Interface

This weekend, I was given MikroKolor Color Graphics Interface by the person who designed the hardware, Paul Andresen. The basic operation was to interface a TMS9918A VDP chip to a TRS-80, Apple II, and S-100, and the output was NTSC color composite video. A color modulator was required to interface it to a TV. A two part article was written for 80 Micro in 1982 by the person who wrote the software, James W. Cole. They took out full page ads under the name of "Andresen's Electronics Research & Development, Inc." "The MIKROKOLOR Color Graphics interface is designed to provide the new TRS-80 Model 100 portable computer with high resolution color graphics and text capability, utililizing a standard color television or color monitor. The MIKROKOLOR provides 256 x 192 graphics, with 15 colors plus transparent. Its 3 dimensional Sprite plances provide for simultaneous display of all levels. I has four modes of operation available: 1. Text mode: Provides 24 lines of 40 characters each using a 6 x 8 dot matrix, and provides 256 user devinable characters. 2. Multicolor mode: Provides 64 x 48 color graphics. 3. Graphics 1 mode: Provides 256 x 192 color graphics, 24 lines of 32 characters each, utilizing an 8 x 8 dot matrix with 2 colors per character. 4 Graphics 2 mode: Provides the same as Graphics 1 mode except allows 16 colors per character." I'm curious if anyone else on the list has one, and has anyone used the unit? It seems like it is a pretty neat unit!
