Getting ready to move to wherever John Lives.... which would be????
Now that I have the time, I would love to restore a 160-A. I'm in the
market for CDC systems or parts of that vintage.
Any one on this list have any of the computers, paper tape equiment or
typewriter? Numbers like 161, 162, 168, 169, 350, 8090, 808X,etc.
I know that the Museum in Mountain View has one, but they have indicated
they are not ready to restore it yet.
Any one know where there are some other dealers or individuals who might
have these systems?

Um .. don't really want to get into a discussion on your drug habits or
what visions they may be causing you .. but what edition of the book do
you have? - Mine (first edition, first printing -- 1983) Has only chapters
1-8 (no 9) and makes no mention of the disk controller... [I looked when
Sellam first asked for information]

Dave

I was given a book the other day called "inside out" Microsoft - In Our Own
Words. have not read it yet just turned few pages, anyone on the list have
this or read it? John
I got the following via email a bit ago:
---[ SNIP ]---
I'm trying to fill out a display that I am organizing for a local museum.
I need the following:
Apple I. Apple II, IMSAI 8080, ALTAIR, Mark-8, IBM 5100, HP 9830, Arkay
CT-650, Minivac 601, SIMON. (They do not have to be working.)
Any help you can give me in acquiring these PCs will be appreciated.
Thanks, Jim
---[ SNIP ]---
Jim is collecting for the Anderson County History Museum and can be
reached at jc3435NOSPAM at charterNOSPAM.net - removing the obvious.
Some of what he's looking for is improbable, but some is more common.

The Vintage Computer Forum
A "DDD Alignment System" is an alignment system using a "Digitial Diagnostic
Disk(ette)"
The DDD is a very special diskette that has various tracks and sectors
recorded on the disk intentionally misaligned. By knowing how the disk was
made (which sectors were misaligned, in which direction, and by how much),
and by seeing which sectors can and cannot be read, the exact alignment
status of a drive can be tested without an oscilloscope or any other test
equipment. All that you need is the DDD disk and a software program that
matches the disk and the disk controller of the target system.
Dysan made these, and perhaps others did also. I have some here for 8" and
5.25" drives.
They are good for checking the alignment, but they are kind of useless for
actually adjusting it if it's off. However, my recollection is that they
ALSO have the analog "cats eye" tracks on them for alignment with an
oscilloscope.
Re-sending as error reported:
Sorry if you got it twice.
Hi ,
Thanks for your answer.
I should now have a disk with the system and PIP (I don't know whether it
would boot though, I haven't tested it yet)
Anyway I was looking at how I could use PIP to transfer the data but I only
managed to find some examples Using the AUX: connector which I think is CP/M
3 (+) and not 2.2 which is the version on the 820.
Do you know more on how I can use the PIP command ?
Thanks.

Hi
You didn't mention if you have a disk that boots and
has PIP under CP/M on it. If you do, you can transfer information as ASCII
like a BASIC source program or even transfer .COM files by first converting
them to .HEX files and then using DDT on the 820 to move them to .COM files.
If you are attempting to bootstrap with no disk, you'll have to check with
others. One may be able to do it if it has a built in debug monitor. Of
course, on can always write some of ones own code and replace one of the
internal EPROMs. It is not as impossible as it sounds. You just have to
explore a little. Dwight

The one that used to be near me didn't sell computers because of support
issues. They started out selling them, then found that no matter how much
they marked it "all sales as is and final", people would come back and
ask for support getting the machine to work correctly.
So they started tossing the computers that were donated, and selling the
rest of the items that came with it (monitor, keyboard, mouse, cables,
printers, software, speakers... anything but the CPU itself).
Alas, they don't exist any more, the owner of the building felt a
Salvation Army store wasn't the right "image" for his property... so he
kicked them out. I was sad for a while, but now a japanese resturant is
going into the building, so I'm happy again.
(now if I can just find another goodwill type store in the area to start
visiting)

H guys,
Couple of weeks ago, I was contacted by a guy who said he had seen my site,
and has an "Black Apple" (Bell and Howell edition of Apple II for schools)
that he would like to sell. Says condition is "unknown", and that the monitor
does not work. From correspondance with him, I have determined that he has the
main unit, two drives of which one is B&H label (no boxes for the hardware),
the dead monitor, no docs, and "lots of software" which is all copies except
for one original boxed game.
Said I was one of several people he had contacted, and asked for a "bid" -
I responded by asking him for a price - he said $150, which I thought was
high, and considering that I would have to ship it here (US -> Canada), I
said "thanks but no thanks", and asked him to let me know if he lowered his
price (because I would like to have a B&H Apple in the collection again)...
He's left me on his mailing list, and since than has reported that he had
an offer for $500, then $1000, and this morning he says he has an offer for
$2000. I corresponded with him again and he says:
>ok right now got offer for 2000 from people in uk. have 2 different people
>in uk that want it for good money.
This seems completely ludicrous to me --- I know B&H Apples are considered
desirable by some, but $2000 (and shipping from US->UK)!!!
???
Smells like a scam... (?)
Whats a B&H Apple worth these days?
Regards,
Dave

Jim:
No, not at all...the timing is off. I think that the Inside Out book
was keyed off of Microsoft's 25th anniversary, while Andy's book came out in
December. Incidentially, Microsoft was founded as a partnership on September
5, 1975.
A search on Amazon reveals that the publication date of "Inside Out"
was September, 2000 while "Revolution in the Valley" has a publication date
of December 1, 2004.

Is there any indication that this book is a reaction to Andy H.'s Apple
book?
