I haven't looked at the cassette circuitry yet, but will eventually get there. Thanks for the offer. On Wed, 18 Mar 2020, corey cohen wrote:
Did you calibrate your cassette interface? I can send you a bunch of software on audio files. You can play them right in front an MP3 player, iPod or smart phone.

Yes. I misunderstood, that is one way to load software.

Isn't that what I'm doing, "virtually" typing the programs througn the serial port? I'm setting the Sol input to serial (SET I=1), then sending the ENT as an ASCII file from another computer to the Sol's serial port.

Why aren?t you loading programs though the cassette port or putting the machine into ?non-local? mode and using the serial port to ?virtually? type in programs?

As expected, I had to replace all of the foam pads in the keyboard. For some reason, the TexElec pads hardly worked at all so I sacrificed a Sun Type 4 keyboard for its pads. Other than that, a couple of RAM problems (dirty DIP switch and a defective 74LS157 multiplexer) were all that I had to fix.
As time permits, I'll investigate getting a couple of 8" drives working with a Micromation Doubler board. For now, I'm loading programs through the serial port at 1200 baud.
