MMD-2

Hey, I've got a couple of E&L MMD-2's here. These are neat little 8080 educational SBC's. Hex keypad, "function" keypad, 7-segment LED's, and three sets of 8 LED's for I/O ports 0, 1, 2. Includes a cassette interface, bus expansion connector, serial interface, and even an EPROM programmer for 2708/2716's. Most impressive! But I didn't get any sort of manuals with them. I've figured out most of the obvious stuff, but it would be nice to know the format expected by the "load" function, the meaning of a few unlabelled switches/jumpers, the meaning of "BRL HI" and "BRL LO", and so on. Anybody remember these things? Thanks, Bill. PS. These things seem to be using the word "pop" to mean "burn", as in "popping an EPROM". Was this a widespread usage? I've heard the words "burn", "blow", and "program" used this way, but "pop" is new to me.
