I can not wait to get back to the back of some of the rooms I have not
been in for 20 to 30 years where I would stash away anything that
looked like a single board computer... who knows... there may be gold in
them thar stacks! #Ed

I would be curious to know the weight of the celebration Apple I, to see
what it's dollar per gram ratio is. Help put things in perspective.

I have a MicroVAX II which has started garbling and losing characters output
to the console. It had seemed that re-seating the processor board would fix
it, but that no longer seems to be the case.
I was just wondering if anyone else has ever come across this failure mode?
Regards
Rob
so, what was the vcf's take?

Wow, how extraordinary a price for such a boring (in terms of design if not

You can be sure it wasn't a vintage computer enthusiast as much as a
business enthusiast who got it... :)
Sorry I'm such a hater, I've just never understood the Apple 1 thing very
much.

The pre-production Apple 1 auctioned via CharityBuzz and displayed at
VCF West closed just now for $1,210,000. Blows away the old record of
$900-something. Amazing!!!
I am looking for an RQDX3 compatible disk image for Dave Gesswein's
MFM disk emulator. I don't have a functional disk to image and the
ZRQCH0 won't cooperate.
Hi:
I'm looking for a PATA host bus adapter card (either ISA or PCI) and a PATA
drive preferably UDMA/33 but no later than UDMA/100. This would probably
come from a system built in the mid-1990s before the PATA interface got
embedded into the chip set. It might even be from an older system that was
upgraded by replacing an ST412 HBA and drive with and EIDE HBA and drive.
Will rent, buy or borrow as appropriate

Hi,
I have written a PDP-8 VHDL model and I have it running in an FPGA
https://github.com/scottlbaker/PDP8-SOC
At this time it has passed a basic DEC diagnostic instruction test but
I found some interesting things when getting that instruction test to pass.
For example:
The following segment of code implies that IAC instruction affects the Link
bit
1797 /GROUP 1 OPERATE TEST 33
1798 02626 7300 CLA CLL /AC=0000 LINK=0
1799 02627 1053 TAD K2525 /AC=2525
1800 02630 7261 CLA CMA CML IAC /TEST COMBINATION
1801 02631 7420 SNL
1802 02632 7430 SZL
1803 02633 7402 HLT /CLA CMA CML IAC FAILED, AC SHOULD
1804 /BE 0000, LINK SHOULD BE ZERO
but the PDP-8 Handbook ; DEC copyright 1966; page 14
says nothing about the Link bit being affected by the IAC instruction.
The simh PDP-8 simulator also shows that L is affected by IAC.
If I change this test line from
1800 02630 7261 CLA CMA CML IAC /TEST COMBINATION << link=0
to:
1800 02630 7261 CLA CMA CML /TEST COMBINATION << link=1
Can anyone point me to:
1) DEC documentation which more fully describes all the instruction set (in
more detail than the PDP-8 handbook)
2) Some more instruction tests in assembler source code format. I have
found lots of binary files but I would prefer assembler source code format.
I am using a pal compatible cross assembler.
Thanks and Regards,
Scott
So, I'm hoping someone can help me with a minor mystery. At same point, I ran
across, and saved, this:
http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/BSTJ_July-August_1978.htm
which is a very nice HTML recreation of the famous first BSTJ Unix issue.
Notice that it contains links to online HTMl versions of two of the papers;
the basic Unix paper (the one that was famously in CACM), and "UNIX
Implementation" by Ken Thompson.
Alas, I appear not to have downloaded and saved the 'Unix Implementation'
paper; I have searched high and low on my machines, and no sign of it. Double
alas, because it doesn't seem to be online anywhere either! I have found a PDF
version online, and also the NROFF source, but not this HTML version.
I just don't recall exactly where I found this, so I can look in the Wayback
Machine for the HTML. I _thought_ it might have been from Ken or DMR's Web
page, so I found both of them in the Wayback Machine, but in sampling them
both over the years, neither one seems to have had this. (And the Wayback machine
doesn't have a search function that I know of, to search for it directly.)
So does this page ring any bells for anyone, or alternatively, has anyone
saved the HTML version "Unix Implementation"? (Yes, I know it's no biggie,
with the PDF version available, I'm just being anal.... :-)

I'm looking for a copy of Turbo Pascal 3.01a for CP/M - specifically a
disk image. I know there's tons of copies in individual-files-in-a-zip
form, but I'd like to get an original disk image. (I've got a problem
with TINST on one of my machines and I want to ensure it's not bit rot on
the behalf of TINST or the data files it uses.)
Disk image format isn't that important as I can use various tools to
extract the files.
Zipping up the files from an original disk would work as well.
Thanks!
