[vcf-midatlantic] das blinkenlights

[Bill Degnan]

I already mentioned this program, but Deeper Thought is better I think, and
easier to integrate with a Rasp Pi.  Note, Jeff may just want to wire
lights directly and not use a Pi to drive it.

Here is an old writeup I did on how to integrate simH and Deeper Thought,
normally not compatible, on the same pidp8.
