Hello! I have an ongoing project to restore a Datapoint 2200 version II and in the process of doing so I created a small simulator for it to understand it better. The simulator is now in the condition that it runs the cassettes that I try on it quite well. The simulator compiles on Macos and Linux. https://github.com/MattisLind/DP2200 A short movie clip when it is running: https://youtu.be/XfsMBhP13ww?si=CHpFKe8eecWjdxDC Having a simulator for a 2200 if there is no software around is no point. There are some tapes on bitsavers.org and a couple of other collectors do have cassettes that can be read. But is there anyone else out there that is sitting on tapes for a Datapoint 2200 (or 5500, 6000, 6600)? Tapes can be read on a normal mono audio cassette tape recorder and fed into a PC which samples the signal, preferably at 44100 kHz with 16 bit resolution. It is important to not overdrive the input of the computer so that the signal becomes a square wave. /Mattis
