RE: In search of 4B3A Microswitch Keyswitches (for a restoration, not a keyboard collector!)
I have a number of keyboards with Micro Switch ST switches, but no SD. Does anyone still use old Memorex or Telex keyboards? -Original Message- From: cctech [mailto:cctech-boun...@classiccmp.org] On Behalf Of Ian Finder via cctech Sent: Thursday, July 09, 2020 11:34 PM To: classic...@classiccmp.org Subject: In search of 4B3A Microswitch Keyswitches (for a restoration, not a keyboard collector!) 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.

RE: A few VT-320 and keyboard questions
The VT320 can use an LK401 or an LK201. I have a defective LK201 you can have for shipping, if you want to repair it. The M0110 keyboards usually used Alps SKCC tall cream switches. https://deskthority.net/wiki/Apple_M0110 I have one complete one https://www.elecshopper.com/apple-m0110a-keyboard-mitsumi-japan.html and an M0110 missing a couple of caps that I will sell for half that.

OK, that’s not really a question. There’s a blank insert where the 25-pin connector usually is; was that a “feature” of the B2 model? (that’s a question but not much of one) …and while I’m here, another question. 4) I have a number of Apple IIs and one III that have sustained some keyboard damage. Where can I get/what is the name of the little plus-shaped keyboard stems for those? If I had a couple dozen that would be most helpful.

I agree that the general introductory blast post was a bit over the top. But I don't think it's been posted here regularly, and vendors that obviously contribute here get a little leeway (Cindy). I figure some may not be familiar with Cypress/Dougherty systems so one intro email per six months or year doesn't bug me. More often will draw some ire ;) If Dougherty Systems wants to participate in this mailing list, there needs to be some 'collector friendly' value, it's a two way street. I suggest that Jeff @ Cypress scan maybe a year of past postings by Cindy @ Electronics Plus, and emulate. J Wow! I feel honored! Jesse at Cypress is actually not a bad guy. Been around a long time, but you are right, they ARE high dollar. I am SO sorry that I could not help more at the Houston haul. I have severe asthma, and it got out of control, so I had to leave. The guy has a TON (literally) of vintage stuff, but he is an ebay guy, and is not willing to part with stuff cheap. One guy drove 15 hours to get there, and did not take home what he wanted, because the guy would not budge on prices. If you want the seller's cell phone to try and make decent offers for some of the stuff in pictures, send me an email. He charged me $400 for 1 Mac 512K, 4 TI/99, and a few old TRS 80 CoCo type systems. I am not going back again, sorry.
