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. I used the high speed cassette interface and while it sucked compared to a floppy it was otherwise excellent. 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. My name seems to accidentally be a secret. I'm the fellow behind the Doctor Who video (not just audio) on the 4P. Really enjoyed the show, thanks for making it.
