Hello

I've got an interesting proposition here - a mainboard from an ADI3 terminal. It looks like a UK101 with the keyboard built onto it, but it is just the PCB/keyboard; no case, power supply or display. I might assume it works, but if it does, what then?

Referring to http://www.retrocomputing.net/info/siti ... dm3-mm.pdf it has a video output similar to the PET's (V-Drive / H-Drive / Video) - well, as far as I can tell. If I wanted to get it to generate a composite video signal, could I use one of those simple mixing circuits like the one suggested for the PET like these : http://www.6502.org/users/andre/hwinfo/ ... osite.html ?

I recognise this question is a tricky one, but it is interesting as a project and it seems a shame to have the PCB go to waste. Its power requirements are reasonably straightforward - 5v / 12v - and the smoothing / rectification are both on the board. It's also got a 15v circuit but that's for the monitor so unused for my application. I'd be using it to link to my Micro UK101 SBC..
