Dear Mr. Allain hello.
If nobody else is interested I would like to have it, if you don't mind
sending it to Fairfax, Virginia. I'll pay of course for packing and postage.
Thank you in advance,
John Savvidis

Subject: save the Mac II (original)
Would somebody please take my Mac II?
I saved it from being scrapped at the office because of it's history,
in that it was Apple's big redesign, the first machine of the new line
-- one that completed with IBM's PS/2 line and argubly was a greater
success. I'm not a big Apple expert but it just seemed if you were
going to have a few Macs that this model would be in the top 5.
This one comes with a HiRes graphics card, matching Ikegami monitor
(17" but compact) cables, software, etc. They don't seem to be that
common, when you strip away all the variants, I haven't really found
a place to get this original model.
Help save the classiccmp.
John A.
My friend told me that they are going to get rid off a
HP E-series computer from their storage. It is a big
box with two rows of switches on the bottom half of
front panel. I am a vax guy and need some $$$ to
invest into my 3900. Do you guys think it worths to
epaying it? Thank you.

I have this INS8073-based board with four TIL-311s, an 8255, a 6116 and
a socket for another, an 82S23 PROM, and an MM58174A. The MM58174A is
a clock/calendar chip for which I can't seem to get the appnote for.
Google reveals an old location at the Nat'l Semi webpage (it has been
removed from their appnote dir), and a single reference at
http://www.nalanda.nitc.ac.in/industry/appnotes/Natsemi/AN-359.pdf
which refuses my connections (could be down, could be blocking U.S.
access; not sure which).
I don't care if the Digital Library of the Calcutta Technical Institute
is up or not; all I'm after is the app note for the MM58174A. Does anyone
on the list have the file 'AN-359.pdf'?
Thanks,
-ethan
P.S. - I realize a picture speaks a thousand words, but does anyone
recognize the device I've described? It was a gift from someone,
years ago. I brought it with me both as a source of TIL-311s and
because it's a complete INS8073 SBC. From what I can gather so far,
it's pretty close to the Nat'l Semi reference design, down to using
a 741-style RS-232 converter for the console interface. The only
useful markings on the PCB are "MC-1N REV-A". The layout of the
TIL-311s and the four pushbuttons on the corners of the front panel
suggest to me some sort of digital timer. There's a 2x5 jumper block
on the front that appears to be input power, serial in/out and a
few of the CPU flag pins (F2, F3). There's a 1x9 jumper block on the
back that seems to be just options, not I/O, but I haven't traced the
whole board out yet.
P.P.S. - in case you don't recognize the CPU part number, INS8073, it's
a microcontroller with Tiny Basic onboard - you wire on a level shifter,
an SRAM and an optional ROM, and _bang_, a microcontroller with a built-
in development system. It's the same processor used in the RB5X robot.
I have had this board for years, and last year, I picked up a few CPU
chips on ePay for a few bucks each. They are one of the many classic
toys I brought with me to play with through the long, winter night.

I have seen some of these before. I had some like this from TRW. Not sure of
the numbers though.
I remember the TRW was printed on a piece of aluminum which was glued on top
of a plastic chip. IIRC one I peeled apart had an AMD 2901 underneath. Most
did not have anything printed on the plastic underneath. Seems TRW was quite
propriatary.
I also had some that I thought were 68000s underneath but with absolutely no
markings.
We had to take the aluminum cap off before they could go into scrap. Never
saw one glued to silicon or ceramic.
2901s were at the heart of some early computers but is not worth the $175.00
that the seller is asking.

I have the Apple][ reference manual and a whole pile of other Apple reference
books and material scanned ... I'd like to make this available, but I have not
done so due to the copyright question - posting a published book which was sold
on it's own merit seems less legit than manuals which came with hardware.
Anyone have any thoughts/experiences on this?

A quick follow-up to this before anyone "jumps" on me - I would not even think
about posting something which is still available from standard sources - I have
not checked to see if you can actually still buy an A2 reference manual from
anyone - perhaps there's someone with a warehouse full of them? As noted above,
this is not something that I am currently considering.
This is more of a "distant future" question - at some point the original material
will not be generally available (this may already be the case for some of it), and
people wishing to learn about these historic machines will have to either borrow it
or steal it (photocopy/scan etc.) - as books get older, rarer and more fragile,
borrowing will become harder and harder, as will physical replication. Are there
any procedures in place to allow this material to be preserved, or does it just "die
off"?
Many of the manufactures of obsolete computer hardware/software that I have been able
to contact have been very helpful. For example, when I asked Dr. Grant, co-founder of
NorthStar computers if I could post the NorthStar OS & software (under my simulator)
and scans of NS documentation, he responded "North Star is defunct so there is no
problem whatsoever. Have fun.". I've had similar responses from a number of other
people who "own" dead computer companies.
Books however are a different matter, with published books, you have both the Author
and the Publisher with interests in the book. I think it would be a lot more complex
to obtain similar permissions, but to be honest, I have not tried - anyone here ever
gotten permission to distribute the content of a published book?

Hey all you AppleII gurus...
I am starting into assembly/machine code on my apple IIc+
If I am in the monitor - how do I get back to basic?
If I am in basic Call -151 takes me to the monitor right?
If I am in the monitor A ! takes me to the mini-asembler
URL for reference for the monitor? for the mini-asembler?
What do I call to get a character? to print a character?
Where is the best place to put my Assembly/Machine code program?
Other pointers, tips, opinions, suggestions?
Thanks!

The proper way to make a real PDP-11 (or VAX or any other Classic computer)
available to everyone who wants one is put them back in FULL PRODUCTION. Not
just hobby, but real full production and commercial sales (for a reasonable
commercial price).
I'm working on a new VAX chip and will soon be putting VAXen in full production.
I can't do the same for PDP-11 because it just isn't my area of expertise, but
my close fried, comrade and associate Stacy Minkin is more on the PDP-11 side
and wants to build a new PDP-11 using FPGA technology just as much as I want to
do it for the VAX.
If you want new PDP-11s, E-mail him at stacy(a)ivan.Harhan.ORG and tell him that
you want to buy a PDP-11 and would be willing to pay a fair commercial price and
possibly finance the NRE cost. Stacy is a real engineer with a vision just as
grand as mine, so given enough people willing to buy this stuff (for real,
commercially, just like in The Days when it was new), he and I can build The
Real Thing: real microcoded CPU, honest-to-Daemon UNIBUS, etc., not a poor
man's emulator.
