I don't recall either the Cyzern or Norcom clones,
but I'm in the process of
researching Tandy/Radio Shack systems and will let you know if I come up
with something.
The Cyzern was advertised in 80-Micro.
I might be misreading your message, but while Dennis
might have built your
LNW himself, LNW wasn't his company. It's possible he was a dealer for LNW
through Green Mountain Micro--his company. The LNW was considered the
Cadillac of TRS-80 clones. I still have a set of photos and text for a
how-to article on building one.
What I meant was Dennis's personal LNW-80. As a fan of his articles
and book, being able to buy his personal LNW-80 was neat.
Several companies such as BT Enterprises sold
souped-up TRS-80s--mostly Mod
IIIs and 4s--under their own brand. This might be the case with your Norcom
system.
The Norcom looks like it was a complete CPU board swapout for the
Model I. In fact, a hole in the top rear vents was hacked out to
make room for the floppy disk edge connector. Since it also is a
Model III rather than a Model I clone, I'm guessing this was an
after-market upgrade. I don't remember seeing any ads for the
board or the company. I've got pictures somewhere. Once I find
them and scan them in I'll post pointers to the files.
