Per my post from last week, after checking out the Decitek readers I ended
up getting a used by warrantied EECO "The Director" MT-82 tape reader with
a short-height spool for a good price.
Here is the manual.

Anyone use this unit? I saw some youtube video display how the servos
appear to treat the tape kindly, that was a selling point. Not as
interested in speed as that's not the point, eh?

Here's my version of tic tac toe in TTL logic: J/K flip flops and a ROM:

Also, in a fairly amazing bit of sleuthing, Jerry Weiss found (in some of the
early PR versions of the -11/84 TM) a diagram which actually shows an
MSV11R-R connected to the PMI bus (on pg 3-63, or thereabouts).
Thanks, guys!
Now, to try and round up enough energy to get my Q/CD machine running, to
confirm that I didn't fry mine. (I don't remember any smoke, but I'm pretty
sure I tried it, to check it, after I bought it.)

Hi, I'm looking for documentation on the MSV11-R; there's next to nothing
online. (An -11/84 manual gives config, but that's all I cam find.) There is
an 'MSV11-R User Guide' (EK-MSV1R-UG), but it's not online; I don't suppose
anyone out there has one?
I'm trying to confirm an online report that it's a PMI card; if so, I want to
put a warning on the CHWiki page for it, to warn people not to plug it into a
Q/Q backplane. (I have one, and did try it back when I first got it, but I
don't recall if I knew it might be a PMI card at the time! I'm too
lazy/low-energy to get my Q/CD machine running so I can plug it in and see if
it still works. :-)
Given the size of the card, and the amount of non-memory logic, compared to
the MSV11-M and MSV11-Q, I would tend to suspect it is a PMI card, but it
would be good to find some DEC docs to confirm it.

Hi - COVID project.... I have been attempting to read some old Honeywell
DDP-516 papertapes using the OP-80A or Teletype reader but it's inefficient
and I don't want to damage the tapes. Does anyone have a reliable
papertape reader for sale, or recommend one currently out there on Ebay,
for the purpose of archiving papertapes of any kind safely and reliably. I
have a reasonable budget. I have a lot of tapes that need to be archived,
so I'd want one that I can interface with to capture into TAP files or what
I would call a raw dump listing of the data in 8-bit Hex. MITS, SWTPc,
Z80 stuf, PDP 8, PDP 11, Honeywell, etc.
End goal is to load tapes into simH, PDPGUI, Altair/S-100, textfiles to
display tapes. I want to be able to view the tape as it would be in Intel
or Motorola format, etc. What does everyone else do?
For example:
S1131C102C20DEBD19217E167DBD185FD6259626A3
S1131C209B27C900D70297037E167DBD1999DE282C

S1131C509C2C2724A600BD02270820F4D602960354
S1131C60BD015ADF2ED62C962DBD015A9C2E270875

Thanks for any advice.

Noel,
Thanks for the book recommendation above. I was happy to see that it was available in a reasonably priced Kindle version.
One of my favorite computer history books is Stan Augarten's 1984 book, Bit by Bit: An Illustrated History of Computers.
I did manage to find a copy and really enjoyed reading it and looking at the great photos in it. I was curious to know
a bit more about the author and in ?DuckDuckGoing? him I ran across an online college course by Haverford University:
http://ds-wordpress.haverford.edu/bitbybit/bit-by-bit-contents/front-matter… <http://ds-wordpress.haverford.edu/bitbybit/bit-by-bit-contents/front-matter…>
that has the entire text and the photos from Stan Augarten?s book. It is a great way to read an otherwise hard to find
book. It also has some .pdfs of the lecture slides from the professors who put this great web site together.

Hey, all.
I was browsing various craigslist places around the US and found someone selling off a substantial collection of classic micros outside Minneapolis
His ad is here:
https://minneapolis.craigslist.org/csw/sys/d/silver-lake-vintage-computer-c…
Through our email chats I've determined that he has these components of an old Heathkit system of unknown workingness:
H8
H17-3 floppy drive
H17-2 drive chassis
Zenith data systems ZVM-131 monitor
Also, he has a terminal made by Data-100, for which I can't find much info but I suspect will be a 3270-compatible terminal of some sort.
He also has a variety of micros, particularly some Atari 8-bit, Apple II , CoCos, and other things. The photos in the ad only show a fraction of what he has. He's not terribly knowledgeable - he came into this stuff as part of an estate cleanout and had 4 pickup truck loads of this stuff, so who knows what has been lost.
I let him know that I would be posting here, so feel free to reach out to him directly.
Anyway, I figured I'd post this here given that someone in the Minneapolis area might be interested in checking some of this stuff out, in a covid-compliant manner, of course...

Hi
Thanks for the replies with the Suns, hopefully I will be able to get one up and running :)
As I should probably clear a bit of space in the ?office? - I have several bits of kit available. I?m in the UK.
HP Visualise 86000 - complete system with keyboard/mouse - nice condition
Several QBUS 11/53 machines with HD (5M I think), two pedestal, the rest ?rack mount? units.
DEC alpha - not sure on model number but functional
VAX 3000 - boots but needs restoration case is in poor condition.
PM me if any of the above is of interest. I could probably ship some of the items.
Thanks
Ian
