In search of 4B3A Microswitch Keyswitches (for a restoration, not a keyboard collector!)

by ian.finder＠gmail.com

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 are bad. 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. Thanks, - I

VCF Midwest Cancellation

by silent700＠gmail.com

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 - - jason If you would like to repost this message in your own forums, feel free to do so by using this link: https://us18.campaign-archive.com/?u=6d177060bd4511e27d05266a5&id=02ddfacc10

About to dump a bunch of Compaq SCSI disk caddies (and disks)

by julf＠julf.com

Hi! I have a box full of Compaq SCSI server disk caddies (with 9.1G disks in them). Feels silly to dump them into e-waste recycling, but there probably isn't much point in shipping them very far either (I am in Amsterdam). Julf

RK11-D "diskless" test ZRKJE0???

by bob＠jfcl.com

? I have an 11/04 with an RK11-D.? I have a couple of RK05s, but I wanted to test the controller before I start working on the drives.? The PDP11 Diagnostic Handbook says that ZRKJ?? "checks only the drive-independent logic of the RK11 controller. no drive is needed..."? I assumed that meant it was a diskless test, but now I'm not sure that's true.? Can anyone confirm or deny this? Does anyone have a listing of ZRKJE0? ? My RK11-D has the BC11 drive cable plugged into the backplane, but the free end of the cable is just lying on the floor.? No drive is connected.? The test fails with ??? RK11 LOGIC TEST I ??? MAINDEC-11-DZRKJ-E ??? REGISTER NOT CLEARED ??? ? PC?? REGADD??? RECVD ??? 002560? 177402? 100000 ?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 is lost, which given that I don't have a drive at all, doesn't sound unreasonable.? Continuing ZRKJ?? also gives ??? REGISTER NOT CLEARED ??? ? PC?? REGADD??? RECVD ??? 002560? 177404? 140200 ??? RKCS ERROR ??? ? PC??? WROTE?? READ ??? 002636? 000002? 140202 177404 is the RKCS register and the first two bits are ERROR and HARD ERROR.? These are both set by the DRE bit in RKER and aren't really a surprise. ? I'm starting to wonder if this diagnostic really works w/o a drive attached, or if these errors are expected. Thanks, Bob

Entrex 480 / Digital Computer Controls 116 in New Jersey.

by mattislind＠gmail.com

I just happen to see this auction: https://www.liveauctioneers.com/item/86804138_entrex-480-vintage-computer-e… Looks like three systems. One marked Entrex 480 the others look like the DG Nova clone DCC 116. On top there seems to be a Diablo printer of some sort. Some rust, indeed. In New Jersey. Then there another auction for several Diablo drives at the same location: https://www.liveauctioneers.com/item/86804145_sweda-750-computers-and-vinta… Also a stack of DG like cards and a core memory board, likely DG or DCC. Not in best condition but probably worth rescuing. Maybe someone in NJ area that want it? /Mattis

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. Stan Irwin

Ancient transistor ?computer board (Peter Van Peborgh)

by peter＠vanpeborgh.eu

OK, now here are some pics that should be available to everybody. I hope. https://photos.app.goo.gl/h64tye8ecmPHQfJD7 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. peter

Amiga - AmiFast 3000

by healyzh＠avanthar.com

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. :-) Zane
