In the early 70s I worked at a place that had 2 S360/40s. On the 23rd floor of a 45+ year old building. At least 8 tape drives, 2 control units for them, 2 full banks of 2314, 2 1403 printers and 2 2540 card machines.
I would assume updated wiring would have to have been run up 23 floors. When I started there was 1 S360/30. Don’t know if the normal building wiring would need to be updated for that.
I, for one, have fond memories of the S/360-20, 30 and 40. I ‘grew’ up running and programming those systems.
FWIW, I have a punch card archive at www.ibmjunkman.com
Does anyone have, or has even seen, a Computer Data Systems "Versatile 2"
s-100 computer from 1977? The company that produced it was from Newark,
Delaware USA and I have been trying to track one down because I live nearby.
Thanks

We're still waiting for VCF PNW 2020, but while we wait ...

(This is a much smaller event than any VCF. It's also quite fun because
it's not overwhelming.)

The Free Software Foundation(FSF) is 40 this week. Central to the thesis of
sharing software this organization has played and continues to play a
seminal role. Though it's importance may be waning due to AI its reason to
exist can't be overstated.
Happy computing

Hi there,
at the beginning of the 90ies I've repaired some Esprit Opus220
terminals for an local computer shop. Problem #1 of those seriaal
terminals was a bad the Flyback Transformer. The Shop managed to
get a bunch of those FBT's new from Taiwan so I could successfully
repair approx 10 of those terminals. I'm still own one of them,
still in functional condition (orange 12 or 14" CRT)..
My stash of goods should still contain two of those Replacement FBT's,
but after a move in 2020 I have to locate them..
So far so good. Now the Problem:
I have an Grundig CD313 monitor from an CNC EDM Machine on the table,
the FBT Grundig 29200-003.05 is bad and I want to repair the monitor
for the small company owning that machine. Unfortunaltely they are
located some miles away from me..
My hope is to locate the two new FBTs and adapt one of them into the
Grundig CD313 Monitor..where I have the schematics for. It where pretty
nice if I could get the schematics from one of that Esprit Opus II (220)
Terminals to look at the wiring for the FBT ..and that's my problem..
has anyone the scheamtics for those Opus terminals?
Regards,
Holm

Checking on if anyone has an old Interact system out there.
It wasn't widely successful, but gained some popularity around Ann Arbor,
MI. I've not come across one of these yet. But I've come across one of
its "Killer Application", a tape-based program called Message Center that
lets users construct banner message scripts with a few video/audio effects.
Would be interested to see this "for real" rather than just in the
MAME emulator. Or also to hear any stories about the system, such as
anyone who actually used one, or saw one being used at a storefront?

Well, just yesterday I tested a set of RWS (RAM) replacement cards for the
IBM 5110 from Patrick Lebbard from Canada - and I'm very impressed. They
work well, I had them running for a few hours.
Details are described here:
https://voidstar.blog/ibm-5110-rws-ram-modern-make-replacements/
or VCF thread
https://forum.vcfed.org/index.php?threads/ibm-5110-ram-timings.1253087/
I don't think he plans on becoming a retailer, they've offered up the
schematic and such. But he did make these boards for me after I shipped
him a set of the base connectors that you need (to adapt them to the 5110's
A1 board) that I pulled from a known-broken board.
His motivation is that he does have a 5100 also that he's trying to
resurrect, so he plans to carry on and make an IBM 5100 version of these
modules also (still resolving a few technical differences between them, so
it's not working out just yet - but the 5110 version of these I can say
seem flawless).
Anyway, exciting stuff to see someone technically savvy enough to probe
signals and reverse engineer 50+ year old tech!
