I stripped dozens of processor boards from 3/60 systems that were then
sold to your employer.

Thank you for mentioning this. I've asked on the list now and again about
a computer I used c. 1976 that had a "lazy-T cursor". I was quite young
at the time and it was only brought to our school for a special occasion,
so my memories are quite fuzzy about it, but having now googled with
some useful keywords, I'm reasonably certain that the device I was trying
to describe was an HP 9830 with an HP 9860 mark-sense card reader.
It seems unlikely I'll ever end up with one, so I'm happy to have found
this emulator, updated less than a year ago...

Thanks again for the very helpful nudge in precisely the correct direction!

Idle curiousity, does anyone happen to know whether the TMS4100 ROM
was a standard off-the-shelf character generator from TI, or was it a
generic mask-ROM-to-customer-order, or otherwise have data on it such
as it's native size.
Full id:
TMS4100
ZA 5705
T-04163
7308 <-- date code
It's the character generator in the HP9830, arranged for character
column scanning order rather than row scanning (7-bits columns at the
outputs rather than 5-bit rows).
I see three possibilities:
- the TI TMS4100 is a character generator ROM
- it's a TI TMS 4100 mask ROM, programmed and sold by TI as a
character gen
- it's a TI TMS 4100 mask ROM, programmed to order for HP
I've sorted out the pinout, so it's not a dire need, just curious.
I searching for a paper copy of the proceedings of the 1952 ACM
conference in Toronto. Our school library only goes back to 1959. To
obtain from the ACM (digitally) would cost several hundred dollars, so
I'm looking for a real dead-tree copy to avoid copyright infringement
issues.
I'm unable to obtain digital access through our library because I'm not
a faculty/staff/student and don't see becoming one for this purpose :-)
If any of you (I know there a few old farts besides me on this list)
could part with a copy (even as a 'loaner') I would greatly appreciate it.
Other issues in the late 40s through late 50s are also interesting, but
current research is focusing on a few items discussed in this particular
volume. The ACM was founded in 1947.
I'd pay for this as well as return postage if necessary.
Thanks,
Gary

Temperature extremes are really not a problem, simply because they are
made for such extremes during normal operation. Moisture can be a
problem in extreme cases, but normally not much of an issue either -
mostly the boxes suffer (and metal tubes, I suppose). The only thing
that really is bad for tubes is salt spray. Don't store your tubes in
a seaside shack.

Hi everyone!
Per some advice here I posted locally on craigslist for items wanted. This morning I received a text message saying "click here to see if my items match what you're looking for." ? it was an image hosting site named "imgsend.com" and seemed nearly-legit. I went there from my phone and said "missing plug-in." Odd. I went there from my Mac. It said I needed a plug-in to view GMP-based GIMP images. GIMP doesn't make GMP images. At this point I knew something was wrong and began to break out my google-fu.
This is what I learned, after you click to "add plugin" it points you to a website that redistributes GIMP with known malware and spyware. Once you have that installed and visit the site to view your photos, the malware is activated, and likely your banking credentials are stolen.
Just something else to be alert for.
Was wondering if anyone had any unwanted working/non-working Commodore
items. I am helping my grandson on a school project.
Thank you
