I am basically looking for 8bit Atari people. And I have two questions. 1) Does anyone know what the cable looks like that you use to hook up your ATR8000 to an RS232 terminal instead of an Atari, for CPM? I believe it hooks into the SIO port of the ATR8000, but I cannot figure out which pins are needed... I have experimented, after changing the jumpers J7 and J10, but had no luck. 2) I want to control my 8bit from my ST. My idea is to have the machine look to the R: instead of looking at E:, for input and output. I have played with this idea and even got my R: handler to replace the E: vector in the HATABS ($31A-$33F) upon booting, but then I get a never ending flow of ERROR 133 (Device or File not Open)... I thought that was the way to do it... I want to use MiNT and MGR and have my ST to use and another MGR window devoted to another machine! I'd really appreciate ANY help on these! -AAron

I have experimented, after changing > the jumpers J7 and J10, but had no luck. SWP sold a proprietary SIO<->DB25 cable that I refused to pay for. I mounted a DB25 female jack on the back of my ATR and put a 3P2T switch on the front. The salient SIO pins are 3 (Data in), 5 (Data out), and 6 (Ground). I wired these to their analogous RS-232 pins on the DB25 (2, 3, & 7), and wired the switch to J7 and J10. Now all I have to do is flip the switch to select Atari or CP/M mode. All in all, the ATR-8000 was a nice piece of work for its day (and for its purpose). Mine still sees some use... >-AAron -jko
