 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.
 I would be interested in the article. I built the later one (E.I., about
1966) with 60 neon lamps as 6 decade shift register/counters and a rotary
telephone dial. This one used 3 12AU7/ECC82 as 6 buffer amps. The diodes in
it I used were from scrapped IBM assemblies. I still have some 6V lamps in
orange plastic holders from the same scrapyard, used on some IBM panels.
