If the 0 feedback winer is rejected Bidder6 will get it for GBP 875.00
one bidding over the second high Bidder9 at GBP 850.00
A third Bidder1 offered GBP 800.00
You say "He is nuts. Period." its more like "They are nuts !"

At todays exchange rate that
is closer to $2500 ...
Even at the GPB 850.00 range it is close to $1500 still a nice IMSI or

If you import, a nice valve amp for about 2K from china.
A pair of speakers from the US.
Ok, back on topic $1500 sounds like price of a nice CP/M system
about 1985.

I guess the board and case is rarer though, even so I think about 70,000
ish ZX80s where made so it's actually not that rare at all, though I
guess unbuilt ones are not that common.
One of the things I do have is a bare Jupiter Ace board, which I believe
only cost my wife ?100ish last cristmass, and they are cirtainly rarer.
Now if it had been a working Dragon Beta prototype.........
For those not in the know, only 3 where ever built, and only one is
known to still be working.

New subject: Tek keyboard request
Greetings from Brazil :o)
Maybe someone has a spare keyboard like the one from this auction:
http://cgi.ebay.com/G57849-Tektronix-3001-GPX-Logic-Analyzer-Keyboard_W0QQi…
As I said before, I'm looking for parts for the 3001 mainframe from
Tektronix. But maybe the keyboard isn't exclusive to this mainframe ;o) who
knows?
Thanks
Alexandre :)

The same can be said for most 1970s minicomputers. And what about
all those cheap transistors in a Straight-8? Wow I guess one of
those is only worth about twenty bucks.

ZX80s are approximately as rare as hens' teeth. Go try to find
one. I have. Perhaps you're thinking of ZX81s.

Nope I have a ZX80 and a couple of 81s (including an unbuilt kit one).
Though since, from your siggy you are in the US, they probably are much
less common over there, I dunno if Sinclair ever sold them outside the
UK, I know that he had a deal with Timex for the ZX81.

They did--I sold a ZX80 to another cctalk-er a couple of years back.
It had a standard NTSC output and 60Hz power supply.
Why anyone would want a cheap piece of plastic like that is beyond my
comprehension. Maybe that's why I'm not a collector.

I think the silly thing is, this ZX80 is only ever going to be a
collectors piece. It will never be used, if it is completed it will
lose 90% of its value. the value of the components are a few pounds
or dollars and you can get 95% of the experience of ownership by
buying a 10 pound/dollar ZX81/TS100 and switching it to FAST mode!
I think ZX80's are overpriced at ?50 let alone ?100 and ?1000. I cant
see them being that rare! Also i have noticed Sinclair QL bits
getting more expensive recently. I'm glad i have way too many of them
already!
I won a nice HP85 on the same auction site two weeks ago for ?27,
bargains are still there to be had!

Silly? Is it any sillier than having a 700lb. computer in one's basement, and doing
most of one's work on a laptop on the dining room table? (That's me, by the way:
my VAX 6660 is a beast. And it's not alone in that basement....)
Would I pay that kind of money for a Sinclair ZX80? Uh, no. But I *have* paid that kind
of money for other items that are equally as "useless" as computing devices (at
least compared to my PowerBook or my dual G4 desktops).
Hello, my name is Ian, and I'm a collector. :-)

Are you using your laptop as a terminal emulator? Then, yes, that's silly ;-)
I don't happen to have a 6600, but I know someone (who used to
subscribe to the list; not sure if he still does) a mile from me that
has a 6xxx in his basement (my largest physical machine would be
either an 11/70 or an 11/750, especially if you include expansion
cabinets and disk/tape units).

?Uh, no. ?But I *have* paid that kind of money for other items that are equally as
"useless" as computing devices (at least compared to my PowerBook or my dual G4
desktops).
The most expensive computing devices I've purchased over the years
were a 32K PET (new in 1978), an Amiga 3000/16 (new in 1991), a
VAX-11/725 (used in 1988), and a PDP-8/S (venerable by the time I got
it). A few items, like my Amiga 1000 or my first SPARCstation, were
under $1000 to originally buy, but were expanded multiple times at a
few hundred bucks per notch, so became somewhat expensive to keep
current.
The only "frivolous" one from that list would be the PDP-8/S. The
others were current or semi-current when I got them, and were each in
daily use for years.
OTOH, the bulk of my DEC machines were free (or nearly free) to me,
but if I wanted to replace them these days, the total cost would be
prohibitive. Starting over 25 years ago, I was lucky enough to be in
the right place at the right time (over and over ;-) to save PDP-8s,
PDP-11s and VAXen from the crusher.
Hello, my name is Ian, and I'm a collector. ?:-)
*in unison* Hi, Ian!

Well I was. Was the difference the fact video stopped when the cpu
was not in the idle key press loop?

Did not a several years back did they try to re-sell old ZX81's old
stock at the same price? ~ $99 US.

Its more than I'd certainly want to pay, though obviously, if the
