Did you actually build one of these? I was thinking of taking the author's
suggestion and upgrading the memory to 10 bits...

Do you have the magazine? If you don't, and get around to putting up a web
page, I'll gladly scan the article to put on it. Actually, if anyone else
is interested, I could scan it and make it available for anyone who want's
to hack around on it. Pretty cool, actually.

Off topic, but one of the more interesting little articles in the magazine
is about the harmful effects of microwaves and describes in gory detail
how animals were adversely affected by them in experiments. What a
different time...just for fun I typed it in and stuck it here, in case
anyone wants to take a peek back at 1960:
