I'm up

After installing the ICs, I tentatively powered up and the 5v rail was reading 8v. Scary, but it was dropping slowly. I was able to deposit and read values on the front panel, which was encouraging, and after a minute or two the 5v supply was down around 5v but continuing to drop. I turned it off when it dropped down to 3v.

Just for comparison, I powered up my vintage 680 and its 5v supply was rock solid at 5.2. I powered up the replica again and now it too was solidly reading 5.05. Very strange. Any ideas what would have caused that? Capacitors forming up? I've no idea.

Anyway, the main thing is it's up and running.

Thanks Grant for another great kit.
