It will be a bit of an unknown wait for the unpopulated prototype 97 CPU board to be delivered so I thought I might try my hand at a Woodstock replacement CPU board while I'm waiting.



It looks ok so far but will need a lot of work to finalize. The one board will suit all models including Constant Memory types.

I really would like a drop in replacement but there are connectors on the original board that have no replacements these days. Specifically the inter PCB connectors of which there are 2 types fitted to these boards. These will have to swapped over from a dead board which shouldn't be too hard.

You never know your luck tho.

On a side note, does anyone know if it is possible to contact Tom Osborne?

cheers

That looks really nice!
The connectors are a little tricky to solder. Getting them all in a straight line is the difficult part. I can't think of a replacement either though.

Cheers,
Harald
