The RICM has 188.8.131.52A and 184.108.40.206 on DAT.
I know what you guys are thinking- no, this isn't for a keyboard collection
or some modern build or some other nonsense like that.
I have a friend who is restoring a fairly interesting and historically
significant vintage computer- a and subject to what appears to be a
batch-related encapsulation failure on the proprietry hall effect sensors,
but could have been some other trauma, around a little over half of them
The correct SD-series replacement switch would be the 4B3A-
*** These can allegedly be found on some of the Diablo printing terminals.**
It is possible other switches ending in ***A could be made to work with a
bit of labor and disassembly (swapping the fairly brittle sensors).
I am not a keyboard expert but I have learned that you can remove a key on
some of these microswitch keyboards and read the model fairly easily.
Please let me know if you have a lead on a donor for these switches. They
will be put to good use, and you can reply to me off list for more details.
We regret to announce...
There will be no VCF Midwest this year.
The conditions imposed upon us by the CoViD-19 pandemic and related
government regulations, as well as a depressed expected turn-out
figure, will make it impossible for us to host an event of the size
and quality our dedicated fans have come to expect. Thus today we
have terminated our 2020 contract with Waterford Banquets and the
Clarion Inn hotel.
We recommend cancelling your hotel and travel reservations, if you
have made them, and we hope that you have not been too greatly
inconvenienced by our change of plans.
We also wish to express our thanks for the many responses we received
to our survey sent back in May. Your feedback was informative,
interesting, humorous and most of all, essential in helping us make
the right decision about this year's show.
The good news is that we have an excellent relationship with our host
venue and have already locked in our contract for 2021. Although a
long way off, plans will take shape early next year for that show, so
please keep an eye out for further announcements of VCFMW 16 (or will
it be 15b? We don't know yet!)
Also, following the lead of other cancelled festivals, we are
considering a Virtual VCFMW to be held on one or more of the dates
allocated for this year's show (Sept 12 or 13, 2020). If we think we
can pull off something half as entertaining as the real thing, maybe
we'll do it. Watch your email for announcements sometime in August.
Your humble(d) organizer -

true.? Can anyone confirm or deny this? Does anyone have a listing of

?177402 is the RKER register and bit 15 is DRE - "Drive Error".
According to the manual this bit is set when the AC power to the drive

unreasonable.? Continuing ZRKJ?? also gives

I recently found an IBM System/36 5360 for sale, with 5251 Terminal and Keyboard. System is supposed to be in good running condition, taken out of service in September 2019, single owner. Asking price seems to be about 10k (!).
Anyone interested should go to this link:
Vintage 1979 IBM 5251 Beam Spring Mechanical Keyboard 7361073 System 36 34 | Almost Anything
- And then use the chat feature on the webpage - the owner will respond to you with info on the system.
I have no relationship with this seller, just wanted fellow collectors with interest in "Big Iron" to know it is available.
OK, now here are some pics that should be available to everybody. I hope.
Smells of (early) 1960s transistorized.
No helpful marking apart from
* "GATE JJ01" on SIDE A. (components).
* "C NT OL DATA" on side B (solder traces).
Big transistors are Motorola "180376008". Also, any ideas what the "246 636
B" boxes are, they have four legs?
A curse on TinyURL and praise to Camiel Vanderhoven.
Anyone have any experience with these? When I installed in around ?97 or ?98, it just worked. Now I?m seeing 0 bytes of Fast Ram on my Amiga 3000, I just see 2MB Chip RAM. I don?t even know if I can boot a base AmigaOS 3.1 with Video and Ethernet drivers. :-)
