Removing paint & magic marker graffiti from computer cases

by edick＠idcomm.com

Excellent suggestion! After you finish, try applying a coat of "Armor-All." Though that's another automotive product, it puts a coat of wax on the case so other forms of grime can be wiped off, and it gives the case a "new" feel. That all-too-common stain and stink from tobacco smoke, by the way, comes out easily with "409" cleanser.

Removing paint & magic marker graffiti from computer cases

A really fine-grit scouring powder like "Bon-Ami" might be what Hans wants to recommend. Those really tough plastic scouring sponges would be appropriate in most cases. You've got to be sure you don't scratch the surface, though.

Removing paint & magic marker graffiti from computer cases

by edick＠idcomm.com

Try benzene (mine came from an art-supply house under the trade name "BESTINE" which is used for removing tape residue.) This may not work on all paints and markers, but it surely does a nice job on the tape and other adhesives used to attach property tags and the like. I've removed some "magic-marker" from plastic cases, but marker and paing sometimes interact with the plastic, in which case you may have a more serious problem. It's just cosmetic, though.

The "FIRST PC" and personal timelines (Was: And what were the80s

by edick＠idcomm.com

This "#@$&*() bull," was part of the party line presented by a DEC sales team at a presentation I attended about fifteen years ago, on behalf of one of the "systems integration contractors" their policies were designed to support. The presenters routinely referred to their clever position in the government market in the terms I used. This was VERY consistent with the way other things appeared at that time. When I worked in other government-related environments, I also noted that, while Digital provided field service, they were not the vendor who provided the original hardware. I was persuaded by this and numerous other statements which had been made to the same effect, by others who worked with the DEC line. I always thought of this as a clever arrangement to ensure that the government got the pitch from their contractors as well as from DEC, and to ensure a sound common basis for DEC to interact with the various contractors with no risk to their business. Because DEC didn't provide the services that these contractors provided, they could be assured of lots of business with the gov because when a job went out for bids, nobody would base their bid on Honeywell or IBM because they provided services at no charge which DEC didn't, and therefore, although perhaps half a dozen entities would bid on a given job, they all would propose DEC equipment. This was at least in part because the same entities who would submit proposals also had people on the inside who wrote the specifications. This worked well for the gov as well as for their contractors. It also worked well for DEC.

Collecting Computers: A Guide - the book.

by kstumpf＠unusual.on.ca

Thank you. The first printing of A Guide to Collecting Computers and Computer Collectibles: History, Practice, and Technique is just about sold out. There is at least one copy of the book in every country of Europe, plus copies all over Austrialia, Canada, and the U.S. of A. A few copies are still available through the Vintage Computer Festival - visit the VCF web site and support Sellam's work. You know that both the computer and antique industries highly recommended the book and many collectors took the time to provide feedback such as "I now know more about myself through your book." Collecting computers is good fun and perhaps a good thing to do. Up the old computer! By the way, will someone please tell me what a pentium is? Yours in good faith. ---------------------------------------------------------------------------- ------------------------------- Kevin Stumpf * Unusual systems * www.unusual.on.ca +1.519.744.2900 * EST/EDT GMT - 5 Collector - Commercial Mainframes & Minicomputers from the 50s, 60s, & 70s and control panels and consoles.

The "FIRST PC" and personal timelines (Was: And what were the 80s

by edick＠idcomm.com

Yes, you're right, but the "video" is the stuff that comes out of the RS170A-compatible, and if you mean the "A" standard, then VERY roughly, indeed. It was more common to see the Apple-][ with a non-Apple monitor for a number of reasons. First, it's likely the monitor was an Apple afterthought. Second, what I remember seeing most was a small (often a Sanyo 9") monitor sitting atop the Apple computer, next to two floppy drives one atop the other. In any case the Apple monitor was too big for that application and it made the Apple not unlike the TRS-80, in that it consisted of too many pieces and took up too much desktop. Nevertheless, monitor or none, the VIDEO was "in there."

I know they produced boards, just like most manufacturers did. DigiKey had something in their catalogs, but its been so long, I don't remember exactly what it was.
