No that's z80 and 8088 cpus running cpm80/86. Amoung other things it would
take up to 896k of ram, color adaptor and a hard disk.

Earl's down here (a liquidation place) has a DEC Rainbow for sale. I
don't exactly remember what they want for it, but i remember thinking it
was ridiculous (probably the better half of 100 bills, maybe more).
However, if anybody wants this particular curio, I will be glad to trot
down there and grab it for you.

Im still looking for a plain Apple][, and an Apple//e platinum, the one
with the numeric keypad on the side, please check if they have any of
either of these, as I need them for my collection.

The MX-80 was the first low cost RELIABLE dot matrix printer and made
printing an affordable reality for we poor early micro users. The Paper Tiger
was (to the best of my memory) the first low cost ($995, again to the best of
my memory) micro dot matrix printer. Unfortunately it was NOT very reliable.
BTW after my post on collecting printers I suddenly realized I have about 12
lying around so I guess I am sort of collecting them - but it's against my
will. :-)

Opens tomorrow. Should be fun!:
"Boston, MA (May 23) - On June 14, 1997, The Computer Museum re-creates the
dawn of the PC age through a lifesize reconstruction of a 1970s' hacker's
garage and vintage personal computing artifacts. ... The Museum draws on
artifacts from its rich collection, including an Apple I and Altair 8800,
to recall the garages of 1970s' hobbyists who assembled "homebrew"
computers ... Rich in period detail, the "garage" is cluttered with an
oscilloscope, a ham radio, an old TV tube, 1970s' issues of Byte magazine,
a drum set, a guitar and photos of Mick Jagger and the Beatles. The relics
- including two early personal computers and two video games - recall a
pivotal time when computers began to serve as consumer items ..."

Well, darn it, I tried, but I just can't get the silly thing to work!
Ok... first volunteer who feels like visiting Kent, WA (yes, Bill, that's
a big hint, especially since I CC'd you on this... <g>) can have this
beast. It's an STC/StorageTek 9-track tape drive, model 2921. When working,
it can do 1600 and 6250 (GCR), sits in a standard 19" rack, has a Pertec
interface, and weighs about 100 lbs. or so.
Notice I say 'when working.' I tried to get it to going, but it seems to
have a sick CPU card. I kind of hate to get rid of it, but I need the space
more than I do the drive and a new CPU card was quoted as being around $800
(yikes! My skylight blinds are going to cost that much!)
Come to think of it, if anyone's got a working dual-density drive that
they feel like getting rid of, I would love to know about it. ;-)
Thanks in advance. E-mail or call me at (253) 639-9555 for details.

Haddock lists it at 150-225... (Values are for complete systems, with

I paid $100 + tax for mine. Took me a while to find it, too.

No Jeff, this Olivetti "sparkling" system was different and was not using
thermal-conductive (=aluminium) paper (at least the one I know); was a real
DRY INK JET.
The "bullet-shaped" cartridge was containing the DRY INK (a sort of TONER)
and a high-voltage electric field was made between the rubber(but conductive)
roll, and the head. In this way the particles of positive electrically
charged toner is "aimed" to go against the negative charged roll, but in
between there is the paper (common paper), so the electricity pass, but ink
stay.

also this DRY system was widely used by Olivetti on desktop financial
calculator (I have one working) and cash-registers
I think that the system was good for those applications (fast,quite
silent,working on common paper instead thermal and..yes,cool in the dark)
but the problem was the powder spread all around the printing bay of the
machine, so when bubble jet came out...
Sorry for my instinctive and not-checked english.

Hmm. I'm getting out of my depth at this point. I've not dealt in
detail with many colour modulators but I recall the Sinclair Spectrum
had YUV as opposed to RGB on its expansion port.
The computer obviously uses RGB internally (although I don't see why one
couldn't design a machine to do YUV instead!) and it has to be converted
to YUV at some stage in the modulation process. My guess (no evidence
to back this up) is that the more expensive modulators - the ones one is
likely to be able to buy for one's own projects - accept composite, but
many mass-producing manufacturers got away with a cheaper modulator by
putting the conversion in the (custom) chip in the video circuitry.
