hi,
I thought you should know the first link you posted, the domain is suspended awaiting renewal see below and the second link does not seem to have xbeaver on it. Interesting nascom stuff mind you. I'm going to stop reading about this stuff now - before i get to back into it!
I only came to these forums for the radio side of things! But i do remember a few of my early computer from time to time, but sadly nothing to help you out - sorry, I have got some old s-100 cards left over in a bag somewhere, 2sio card, z80 card, memory cards, i think a tarbell disk controller maybe. I did used to have an altair8080 (my first computer) but that was disposed of by my dad when i moved out.
