I've no direct original experience with the Model 4, but I do get the impression that few games were made that required a Model 4. The 128 x 48 graphics weren't great but nonetheless there were excellent versions of arcade games such as Asteroids, Targ, Berzerk, BattleZone and Defender. In case anyone gets the wrong impression, there was all manner of software available for the Model III including many games. If we'd been able to afford a floppy we'd have dropped it in a heartbeat. I think a large part of this was using a frequency modulation scheme rather than the square clock pulses of the 500 baud format. Very reliable and the 3X speed over 500 baud made quite a difference. The Genie IIIs worked seamlessly with G-DOS, NEW-DOS or CP/M operating systems and was renowned for its high-resolution graphics. ![]() I used the high speed cassette interface and while it sucked compared to a floppy it was otherwise excellent. The TCS Trommeschlger Genie IIIs is a legacy computer system manufactured in Germany that was largely compatible with Tandy's TRS-80 systems. Except for the RS-232 the bottom cables weren't such a big deal since they're all card-edge connectors which naturally have a 90 degree connector. I think even before the 4D they put the RS-232 connector out the back at some point. The Model 4 was introduced with all the cables (except cassette port and power) out the bottom like the Model III. The Model III never came in an uppercase only version and the Model I supported 32 x 16 character mode it wasn't introduced with the Model III.
