Hi,
Two years ago I've found scans in PDF with the article (dated 197?, I don't
remember) describing DIY TTL-based calculator. This was microprogrammed
machine (if I remember correctly microproprogram was "stored" in the diode
array). It has LED display and possiblity to calculate square root.
Definitely not talking about EDUC-8 computer from 1975. I think this
calculator was published a little bit earlier.
Unfortunately I'm no longer able to find it. Does anyone associate the name of
that magazine?
I think one is hidding at BITSAVERS.
