Wanted: SuperQBoard, v3...

Wanted, SuperQBoard, V3, OR the contents of the GALs. Mine has been laid low by an accident and many of the ICs are damaged. I'd like to fully restore it. It's more or less essential to my well-being to have a working SQB!

Can be 0K.

Any serious offer considered.

Didn't Keith Mitchell work out the equations years ago?

Yes.

However, I don't want to recreate one. I want an original one, as it's the first thing I personally made. It's also the heart of my system, and my original one is really not repairable.

It is! It's one I put the cover on too back when it was made! Probably still has my teenage prints on it!

Interesting that has a second set of pads just behind the 64 way edge connector - was that for a possible extension?

By installing turned pins in that row, a 512K mezzanine card could be installed. That is why the ROM was not socketed - the contents were mature, and if it was socketed the height would be too great. The turned pins were added as a second process, so I would often spend my days with a solder sucker cleaning out the holes.

Good times.

SQBv4 retains this feature. Only now the card is 4MB. That 4MB card will fit the SQBv3 too.
