Should this be considered an ancestor of laptops?

WTD: Card separators/risers

by dwight.elvey＠amd.com

Hi I'm sure McMaster-Carr has them but of the original group he stated also had them. He was just looking under the wrong name. He should have been looking for standoffs or spacers. The digikey catalog on my lap has them indexed as Harware/Spacers/Standoffs. As a general rule, any hardware that McMaster-Carr doesn't have just plan doesn't exist.

US Robotics PC?

by cclist＠sydex.com

This was back, oh, in about 1978. I was at one of the trade shows (don't remember which one) and there was a fellow with a computer with integrated monitor, disk drives and a printer (sticking out of the top) in a fairly large black box--probably Z80, but I can't be sure. I remember that it was USR because of the unusual name of the company. Has anyone else ever seen one of these beasts? Cheers, Chuck

WTD: Card separators/risers

by billdeg＠degnanco.com

Hi - I searched for card separators on Digikey, Code Micro, or Jameco (some people call them "risers.") - no specific luck. I have emailed them for assistance. In the mean time... As I wrote before I am trying to install a small computer board on top of a computer motherboard, so that the smaller board is about 9/16" separated >from the motherboard. There is not much clearance and I want to just make it a few hairs above the IC's on the motherboard or I can't close the lid of the computer. There are holes in both boards that line up for the risers (the small board is made to be attached to the motherboard with risers). My local Radio Shack's card separators/risers are either too short or too tall. The card separators/risers have screw holes on either end so that you can fasten them to the boards. Does anyone in this group have four 9/16" risers that they'd like to sell or trade me? I actually found two in my supplies, but I need four of the same height. If anyone would like a picture to get a better idea of what I need, let me know via private email. Bill Degnan

bogus auction for Altair system on eBay

HP2648A tape drive capstans

by legalize＠xmission.com

Hey, so I'm glad that I read a web page (can't remember the URL, sorry... linked from the Nike Missile site, I think) about refurbishing deteriorated parts in old machines. I bought a 2648A main unit (would love a keyboard for it, if anyone has an extra) and opened it up last night. The tape drive capstans have turned to a puddle of goo! So I figure that if I ever want the tape drive to be in working order, that I need to: i) remove the goo ii) recreate/replace the capstan Does anyone have a unit with an intact capstan that could give me physical dimensions? I doubt anyone has a repair kit that would include the capstan, but that would certainly be welcome! Aside from the capstans and a little dust inside the case, the internals look fine. The case has a small crack in one corner, but otherwise appears in typical condition for its age. This thing is basically a microcomputer... when I used them back in 1979, I had no idea that there was this much electronics inside the thing! I do have the user manual from bitsavers, but it doesn't go into repair stuff, just installation (which is how I figured out how to open the case) of options. As always... thanks! -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>

If they have a lot of buying from the same seller, it is a good chance that they are a shill. Also a quick check of the sellers feedback will often find several shill names. Ebay doesn't seem to do much more than warn the seller when they are notified. This is even when it is obvious shilling. Dwight

Xenix 286?

by compoobah＠valleyimplants.com

{The Design of OS/2} by Deitel and Kogan (how do you delineate titles of books when you can't underline or italicize?) seems to indicate that the triple fault switch back to real mode is relying on a "feature" of the 80286, since for the reset method it talks about the hardware involved (keyboard controller on AT, I/O port electonics on PS/2). The book also makes the note that "compared ot the other alternatives, the process [triple faulting] is a slow one" (285).

WTD: Card separators/risers

by dwight.elvey＠amd.com

Hi These are usually called standoffs. Digikey has many types and sizes. Give me material and thread sizes and I can give you a digikey part number. Dwight >From: "B.
