It sure does look like a nice part, and it even
comes in PDIP. But how does one buy them? Using
http://www.findchips.com (I agree, excellent site) and
PartMiner, I can find only one distributer that admits that
they exist; Marshall lists a single form of it, the LQFP
UPD78F0034GC, at $6.15 each when they have them; however
it's out of stock and the quoted lead time is 112 days. The
base emulator system (the IE-78K0-NS) is known to Sterling
and Future; Future lists it at $4,755, "Call for Stock" --
debug software, adapters, simulators, etc. extra. The
assembler, RA78K/0, seems to cost $395, the C compiler
$655.

It would appear that, should any of these items be
available anywhere, a full development system wuold
cost as much as $7-10K?

Perhaps we could set a new rule: When recommending
an alternative part, the recommendation needs to
include the cost of the development system and
a place one can buy it and the parts. :-)

I can get them 8wks lead times. Our price was in the
$5's (10k/year), and the total dev kit (ICE, *and* IAR
compiler) was around $5000.

Are you buying from RS or Maplin? ;))

NEC is not in the hobby-ist game, so you won't find
onesies and twosies.

Well, you know, if Marlin P. Jones doesn't
carry it, it's not worth having...

Not even tensies and twentiesies? Maybe tubesies? :-)

There is a tiny niche between hobby and volume production,
where even the cost of a deveopment system is justifiable,
but the volumes don't justify, on either side, schmoozing
with the local sales force. uChip, Atmel, and many of the
8051 vendors seem to be quite happy making products
available to that market. It would be easier if vendors
that didn't want that kind of business would be more up
front about it: "Our products are only available in carload
quantities", or something like that.
