[Coco] tandy 512k board and the triad board & MPI test

[Mark Marlette]

I have seen enough power supply failures through out the years.

With that said, I have also seen many 512k systems run 24/7.....hot! :)

The surface temps on the DRAMS are over 150 degrees F, that is very uncomfortable to the touch.

SRAM temp deltas from ambient hardly change.

Which should mean that meager poor ole power supply should last longer
too.. right?
