TexElec Foam and Foil" Capacitive Pads for KeyTronic & BTC Keyboard Repair

by Marvin Johnston

O n t he recommendation of a couple list members, I ordered five of their Foam and Foil" Capacitive Pads for KeyTronic & BTC Keyboard Repair. I thought the price was very reasonable for about 100 pads for each of the five bags plus shipping. Keyboard disassembly was rather tedious, but not particularly difficult. My guess is about a day to complete the job on a Vector 3 keyboard. An Installation video on Youtube is available... search for "How to fix a Keytronic foam and foil keyboard" and you should fnd it. To me, it helped out immensely covering foam pad removal and reassembly. arrival took about three weeks. Hopefully see everyone in September. Marvin

FYI, RIP Ed ---------- Forwarded message --------- From: W2HX <w2hx(a)w2hx.com> Date: Sat, Jun 15, 2024, 1:22 PM Subject: [GreenKeys] FW: [cca] Ed Sharpe, KF7RWW, SK To: Greenkeys <greenkeys(a)mailman.qth.net> FYI 73 Eugene W2HX *From:* cca(a)groups.io <cca(a)groups.io> *On Behalf Of *Scott Johnson via groups.io *Sent:* Friday, June 14, 2024 6:52 PM *To:* cca(a)groups.io *Subject:* [cca] Ed Sharpe, KF7RWW, SK All- With sadness, I must report that Ed Sharpe, KF7RWW, passed away 1 June 2024. He was 72. Ed was a consummate archivist, and had a large Collins collection, which he housed in a Historic house in Glendale , AZ, known as the Coury House. This was the home of SMECC, the Southwest Museum of Engineering, Communications, and Computing. Ed was a USAF veteran, a ground radio repairman stationed at Luke AFB in the early seventies. Ed haunted many of the vintage and military radio sites and garnered much of his collection through these channels. His rampant enthusiasm for technology of any kind will be missed! www.smecc.org https://www.dignitymemorial.com/obituaries/glendale-az/edward-sharpe-118465… Scott Johnson W7SVJ _._,_._,_ ------------------------------ Groups.io Links: You receive all messages sent to this group.

Heurikon HK68/M10 (Multibus) information?

by Chris Hanson

Does anyone have any manuals or other information on the Heurikon HK68/M10? Or the Hbug ROMs for it? The HK68/M10 is a Multibus 68010 board with serial, SCSI, parallel, timers, 1MB onboard RAM, 2- or 4-channel DMA, and an optional 68451 MMU. It's similar but not identical to the HK68/V10 (the VMEbus version) and so far I haven't been able to find much that would make one usable. I'm particularly interested in: An Hbug ROM. Pinouts for the top edge connectors, which provide the serial ports, the SCSI port, and the parallel port. Jumpering/strapping and other configuration information. And of course it'd be incredible to find the UniPlus+ distribution for it, but I'm not holding out much hope for that. I already know what's on Bitsavers—such as the brochure—and I've already looked at the MAME HK68/V10 emulation, so no need to point those out. -- Chris

L. Conway

by Murray McCullough

Today I came across an obituary of Lynn Conway, computer pioneer in the field of VLSI(along with Carver Mead) and also in one called dynamic instruction scheduling(used in supercomputing world). More to the point Conway was transgender and suffered for this, an almost forgotten pioneer in the microcomputing and supercomputing fields. Also, as a researcher at IBM and Xerox Parc where she contributed to the first years of microcomputing, the GUI and Ethernet protocol development. Eventually the IEEE recognized her contributions as did IBM - better late than never! Murray 🙂

Experience using an Altair 8800 ("Personal computer" from 70s)

by Dave Dunfield

I case anyone is interested... I've just passed on my "Mits Altair 8800" - this is a very historic system from the 70s - it is: First Personal Computer (long before IBM PC) First S100 buss system First system Bill Gates wrote code for (long before Microsoft) I did write a pretty decent emulator for my exact Altair system some years ago... And with recent interest in the system, I've just updated it with a few minor improvements and a "cleaned up" edition of the software I created to bootstrap a hardware front-panel based system (no on-board ROM) via a serial port card - requiring you to enter only 18 bytes through the front panel So .. if you'd like to experience what it was like to use a system from the 70s - here's some of the things you can do: Bootstrap it cold Run NorthStar DOS (one of the first commercial DOSes) Run DMF (Device Management Facility) - a DOS I created for it - can you tell that at the time I was working on an IBM mainframe ... my - OS name sounds a lot like various IBM mainframe packages at the time. A few other software setups (for example there's a stand-alone bootable FORTH) Has Editors, Assemblers, BASIC and other tools from the era. and a few games - some written by yours truly - some very early commercial offerings (like "Cranston Manor Adventure", or "Valdez") Note1: My Altair emulator was created under DOS and is a 16 bit program! It does work very well with DosBox (I recommend the one on my site) Note2: I've not updated the ALTAIR.ZIP on "Daves Old Computers" yet - you can get the updated one from: "Daves Old Computers" -> Personal -> Downloads -> OlderDownloadsFromPrevious - look for "ALTAIR" under: Simulators and Emulators *** I don't follow this list nearly as much these days - if you want to reach me, use the contact link on my site! -- ---------------------------------------------------------------------------------- Search "Dave's Old Computers" see "my personal" at bottom!
