To whom it may concern,
I am interested in buying or renting the Amstrad PPC640 for a movie called ETERNAL SUNSHINE OF THE SPOTLESS MIND Staring Jim Carrey and Kate Winslet. The movie tells the story of a couple who have elected to rid themselves of their memories of on another by a machine.

I've been looking for a Symmetric 375, but those seem to be rare as hen's
teeth. Does anyone have something like a Whitechapel MG1 or a Tektronix
6130/4132 looking for a new home?

Hopefully these systems aren't stored near any cedar shavings used for
stall bedding, as the fumes from the plicatic (sp?) acid in the cedar
can damage any copper used in circuit boards, etc. Does anyone know
if the abietic acid in pine shavings/dust causes similar problems?
R. D. - I don't use cedar or pine shavings, just plain wheat straw.
The temperature varies across the year. The computers are in wooden
boxes, not cedar or pine, and the inside is covered with a black plastic
that rodents don't chew on. They have been in the barn since the summer
of 1987. I think they're all intact. Have to see this summer.

NOT plastic. Acetone, MEK, toluene, and many other organic solvents are
sometimes supplied in 1-litre pastic containers but should not be kept in
plastic for long-term storage. Even polythene bottles will be damaged in
the long term -- they go brittle as the plasticisers are leached out.
Such things are normally kept in glass bottles for small quantities, say up
to 500ml, or metal tins for a litre or more.

Is it kept somewhere warm? It should be kept cool (no more than 68deg F).
If it's reasonably pure acetone, I can't think of any reaction it should
have with steel or tin, so I guess what you're noticing is evaporation
causing a slight pressure buildup in the can. Unless it's contaminated --
it doesn't co-exist well with some other solvents (such as chloroform) and
moderately strong oxidising agents, or some catalysts (including some forms
of carbon).
If it's rusting, then you should probably replace the can before it becomes
weak enough to leak.

I need the counter function but I'd like a copy of the PDF anyway.

Same here. I squirreled away a lot of parts over the years but found that many of them were damaged due to the foam. Fortunately I've get some pretty good scrap sources and I've been finding lots of military grade cards with socketed ICs in the last couple of years so I've been picking them up and pulling the ICs and storing them in parts cabinets. I've amassed a huge stock in just the last year. I was also lucky last year and picked up a good number of parts cabinets that have all the drawers made out of anti-static material. I had been keeping the parts in anti-static foam for AS protestion but now I don't have to.

I have a fair number of 308 and 311 displays that I've pulled from cards and the local surplus place has plenty of them but the 306/307s seem to be scarce.

Sounds like you got the keyboard that goes with a Tek 7854 scope. With the keyboard you can use the scope to do some calculations based on the measurements that it's reading. I think the keyboards are a bit scarce. Probably worth a few bucks to someone that needs one or on E-bay.

Hi all,
Sorry about the short intro. A bit more: I' a computer teacher; been
in the business since 1970
when i learned COBOL programming in Toronto. I earned a BA and BEd and
taught ESL
in Africa and Asia.
My first computer was CompuPro and the Intercept Jr. 6100. Sorry to
say they're no longer
active as they're in storage in the barn. I raise horses.
The computer I still use from vintage era is the Coleco ADAM. Us
Adamites keep are
favorite machine running despite its early orphan status.
I now have an 800 Mhz. Celeron machine. I wrote a book called "A
Historical Research Guide to the Microcomputer" which covers the 4/8 bit
era as a supplementary paper for my PhD.
I try to follow what's happening out there but I'm afraid I have
limited time. Too busy!!!
A great excuse...

Subject: Eagle Computer
I have an original Eagle Computer with this huge external ( as in big
goofy looking box ) 10 megabyte winchester hard drive, 5 1/4 " floppy and
documentation. It stills fires up under MS DOS and I believe it has an
original version of Lotus 123 on it and maybe word perfect. It's been so
long I dont even know whats there. Who knows it may even have some vintage
porn on it.. Any interest? What is it worth?

Anyone need/have a use for Honeywell M4260 disk cartridges?
Look to be about 8 inches in diameter, enclosed square case. Looks like a
'slide in' type drive. With dust covers/cases. Appear to be in good
condition, but I have nothing that will use them.
Have six of them.
