Ah, I didn’t know about the square one. Mine is a Blackhawk unit and it has a DB9. I hacked my CM-8 cable, cutting off the end and putting a DB9 not he cable, then the opposite gender on the cut off square, so I could move my cable between CoCo and MM/1.

Now, I have not looked at the Microware MM/1 I have — it was an early model, so it might have the CoCo connector.

It didn’t dawn on me I could go SCART with this but that makes sense. I just need someone to build me the DB9 cable (though maybe I could manage that little bit of soldering).

Also, uptopic was a mention of a modern monitor that would “just work” with the Amiga, etc. so if that could work with CoCo and MM/1, I’d love to have something like that. I need a new monitor for it anyway ;-)
