MITS Altair 8800 C&K switches
by Herb Johnson 13 Apr '20

13 Apr '20

An odd thing. I was trying to buy some C&K brand "toggle switches" for a MITS Altair 8800 front panel. I could not find on the Web, a good photo of it's front-panel PC board "naked" to see the original switches; so I could buy one of the proper size. Specifically, the length of the "neck" below the toggle lever. Does anyone have such a photo, of the unmounted PC board with switches, or a photo of of the actual real original switch bodies, or a measure of the physical length of that mounting-shaft? The length does vary. Just to be clear and exact. I'm talking about the original model of the MITS Altair 8800. NO 8800a, no 8800b. These switches have a narrow round "toggle" - not the flat wedge-like toggle on the 8800b and 8800a. And no, MITS doesn't have a C&K number, and no sketch in their original manuals (that I could find). And a Web search for such images is a nightmare. Bunches of faux Altairs, faux front panels. Some number of original Altairs - with the front-panel PC board covered of course with the decorative front-panel. Or poor, low-rez photos from 15 years ago. I've made a good guess, without disassembling my own 8800. Looks like 11/16 inches from base of threaded shaft to top of same. Looks like a 3/4" net length from the base of the C&K body to the top of the threaded shaft. These are eyeball measures and are not likely what are in the C&K 1975 data sheets; but these provide clues. Can anyone measure the damn thing? Or take a clear photo and point me to it? Looks like I'll haveta take a lot of photos, next time I repair the real deal. Regards, Herb "missed" Johnson -- Herbert R.

OT: HP 660LX Color Palmtop PC available
by svcatitc＠aol.com 07 Apr '20

07 Apr '20

So that the final disposition of the HP palmtop is not in question, it has been spoken for. Many thanks to Bob Shuster for his assistance. Bill Inderrieden ---------- Original Message ---------- Jim Scheef js at sdf.orgTue Mar 31 23:21:59 EDT 2020 The HP660 is eminently collectible along with the other four or five models in the HP palmtop product line based on WinCE. The DOS-based palmtops starting with the 95lx are even more interesting although not as 'rare'. Hopefully someone will take Bob's offer.Jim

by Jeffrey Jonas 05 Apr '20

05 Apr '20

Paywalls and membership only databases are annoying. One obstacle has been temporarily removed: The Association for Computing Machinery (ACM) announces: "To help support our community working remotely during COVID-19, we are making all work published by ACM in our Digital Library freely accessible through June 30, 2020." e.g. http://dl.acm.org/citation.cfm?doid=307824.307853 -- on MindForth AI -- is now freely accessible to read or download as a Portable Document FIle (PDF).
