I built an Accu-Keyer in 1973. If you are an ARRL member you can see a rather
poor copy of the original article here:
http://p1k.arrl.org/cgi-bin/topdf.cgi?id=62617&pub=qst
The Accu-Keyer has self-completing dots and dashes, dot and dash memories,
iambic operation, dot and dash insertion and automatic character spacing.
The Accu-Keyer spawned the Accu-Memory
(http://p1k.arrl.org/cgi-bin/topdf.cgi?id=67877&pub=qst) which added memory
storage. I built a couple of these, giving one to my friend George, W6TC, and
adding another couple of circuit boards full of TTL ICs to another one for
myself that added automatic changeover sequencing, transmit/receive timing,
etc. for automating my EME and meteor scatter schedules. It's still out in my
storage building. Another thing for my widow to dispose of.
The Logikey and Curtis stuff basically has the capability of emulating some or
part of the features of the Accu-Keyer.
