   It's a real shame that your father threw out the instructions. The MMDs are pretty scarce and I've never seen the instructions for them. I used to have one but gave mine to Mike Haas. There were also a couple (with a bunch of add on cards) that were sold on E-bay recently. They were located in Australia.

My problem is that I've never programmed anything like this before, and I'm having a hard time understanding anything of it. I have read a few threads in this list about the MMD-1, but they didn't help much. Let's say I want to put a number in one of the ports, how do I do that?
