Point to John: the machine offered for sale is called an
IMSAI Series Two, not an IMSAI 8080. However, its arguable
that many existing IMSAI 8080s ceased being IMSAI 8080s
when the owners stuck in a Cromemco ZPU, a TDL Z-80 CPU
board, or somesuch.

However, quoting from the main web page:

: Delivery is currently 6 to 8 weeks from the date of order.
: Please check with us for confirmation of shipping date.
: Assembled IMSAI products are shipped factory assembled
: and supplied with a no-hassle two-year warranty on parts
: and labor UNLESS specified otherwise. See the warranty
: details on our ORDER page.

Now, I don't have a kilobuck laying around with which to
test these statements. But as to my original statement,
clearly, people spending $1200 for an original either
have little interest in running the thing, or, at very
least, want an "original" more so that they can say it
is an "original" over and above its value as a working
system. If its value as a working system is more important,
they'll consider buying the Series Two.

And if the Series Two is still vaporware, then all I can
say is that is a _very_ old tradition in the microcomputer
field, and I think I'll have to write up my experience with
Processor Technology and the Sol as an example of this (I
still have all the "soon" letters I got from them).
