Hard to believe that it was over 4 years ago that I wrote the original E-mail asking about this! Anyways, I finally found a picture and a brief "product announcement" of the expansion board - it was the CompuScope SuperMother - I used to have for my first Vic-20 back in the mid 80s. I've included them below. I found them in the September 1983 issue of MicroComputing. I never did have the original instructions or cassette tape software. However, that "BlockSave" software sounds like it would have been neat and handy to try back then! Enjoy!

This expansion board was as wide as the Vic-20 and if I remember correctly about 1.5 times as deep. It had a ton of cartridge slots in it. You could put all of your RAM expansion carts in and then put in a bunch of game cartridges as well. There were two rows of cartridge slots on this board. The slots for the "games" had switches to enable them before powering on. That way if you had 3 or more "favourite" game cartridges you could leave them plugged in all the time and just flip the switch for the one you wanted to play. Sadly, there came a time where I had to sell all of my Vic-20 items so I no longer have that expansion board. :( I can't remember what the expansion board was called but I suspect after reading the "Cartridge Rarity List" that it was the Compuscope Supermother. The description almost fits what I can remember about the board that I had. Does anyone have any pictures, docs, etc for this Compuscope Supermother that they could E-mail me? I've searched for some via Google but so far haven't had any luck. Thanks! :) Ken Rath
