The Voltera is cool. Now I have mine working well it shaves so much time off of the previous method of using stencils.

While they was all tested before going in the cleaner, they are tested again afterwards.

Being too poorly to do much else today, I started dabbling with a 68K CPU relocator for the 70789 boards. So this way the TOS206 decoder boards & 16MHz booster can be fitted in the original STFM case.

It is a bit of a squash in between the 4MB MMU RAM board and the MB keyboard post hole, but it *just* fits.

This board will have the bus pullups on it and some caps later..

Went to Eagle 9 to try to speed up some routing (I like the auto DRC over V7) but like 5 minutes into it all...



Same old BS again. Eagle has more bloody bugs than our back garden! :roll:

I mean seriously! :WTF:

I have managed to squash up the 4MB MMU RAM board a little bit. Effectively moving the connector further inwards. It should help miss the CPU relocated boards in batches in the future.
