You are confused. The 8080 is a single chip cpu that requires support chips. The F8 is a single chip cpu that requires support chips. The 3870 however (or 8048) are single chip microprocessors. See the subtle difference? Also the F8 is not as complete a cpu as the 8080 as it really has to have a lost of stuff around it or special chips to get a nominal data/address bus to interface to convential rams/roms. Allison

Top 10 Holy Grails of Classic Microcomputer Collecting

by kaikal＠MICROSOFT.com

Funny you should mention the OSI's, a saintly coworker just gave me a C4P-MF and a C3D today. The C3D is the one you were thinking of with the 3 different CPU's. I also 'always wanted' a CompuColor II, and finally found one last year, it's REALLY rare. http://www.geocities.com/~compcloset/CompuColorII.htm Still looking for a Sorcerer, but I have a couple of leads from the VCF. One gentleman has two of 'em, one of which has the S-100 box. Hasn't replied to my email yet though...

I'd be happy right now with any Ohio Scientific system. Though I'd really like the one, can't find my notes for the model, which had 3 processors. A 6502, Z-80 and 680x if I recall. Have the notes on it around here somewhere. Of course I'd add all of Kai's to the list too but that would throw me over 10. ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

New Acquisitions

by hhacker＠gte.net

I worked at the Los Angeles Air Force Base in the mid 80's and one of the requirements for personal computers of the time was called TEMPEST. Computers meeting the TEMPEST specification contained such hardware as necessary in order to ensure that electromagnetic radiation emitted from the computer would not be able to be monitored in such a way as to determine the use to which the computer was being put. More simply, one would not be able to eavesdrop on the computer user, since there would be no discernable message in any electromagnetic radiation coming from the computer. Perhaps this is what you have. This would explain the extra shielding on cables and the double walled chassis. -----Original Message----- From: Marvin <marvin(a)rain.org> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Saturday, October 10, 1998 12:10 AM Subject: New Acquisitions >We've all heard talk about how great amateur radio events are for finding >good stuff.

New Find

by lwalker＠mail.interlog.com

I keep adding to my collection regularly but this is notable. A Kaypro II to go with my (as yet non-functioning) Kaypro 2X. It was in an incredibly jammed little junk-store which remains unplumbed by me for now. In Sam's catergization scheme ,this would rate as a cockroach-market There were 2 walls piled high in a narrow shop with everything imagineable , leather jackets, jeans and toasters just tossed in a pile on top of each other with barely enough room to get between. Saw lots of old printers and monitors but at the bottom of one pile I could barely discern that tell-tale Darth Vader Blue form. It was dusty and dirty on the outside but clean-uppable and when I opened it up at home the KB was impeccably clean. It had cardboard inserts to protect the fdds, and the A drive's insert had a bill for $565 ($185 parts) with the owners name and phone number. I surmise the owner was told the price and never reclaimed it. Sounds like I have a Refurbished machine here ! :^)) ciao larry lwalker(a)interlog.com

The most obvious difference is the japanese characters on the keyboard. The "[" key in the lower right corner (next to the spacebar) is instead a toggle key (like capslock or grph) that switches into japanese mode. It also says "personal computer" under PC-8201 next to the screen, whereas my 8201a doesn't.

Current Tracers

by jeff.kaneko＠juno.com

Holy smokes! You're right! They're not in the 1998 catalog, but I found them in the 1996 catalog: HP-547A Current Tracer-- $975 ! I first saw these over 15 years ago-- the prices were *much* lower then! Ahhh, it looks like they don't make 'em no more. Bummer. But that was at most, two years ago. Not bad.

How to identify comm hardware you pass up

by dastar＠ncal.verio.com

Hey, here's a tip. If you're interested in knowing to what use you can put that communications hardware you keep passing up at your preferred source for classic computers, get yourself a Glasgal Communications catalog. The older the better. Glasgal was a company that sold thousands of communications products, from cables & connectors to muxes & switches, and everything in between (and I'm talking everything). The catalog I have from them is 1987, and has some pretty interesting stuff in it, including things I've seen at thrift stores or surplus shops, or things I've worked with. This particular catalog is called "System/Configuration Guide and Product Listing". So not only does it describe their complete product line but it also goes into technical discussions about certain products and their applications, including diagrams. Its basically a tutorial on how to hook up and use the products they are selling. It is very thorough and extraordinarily useful if you'd like to start building your own communcations network between disparate computer storage sites with old comm hardware. I found this particular catalog in a thrift store. Alas (homage to Tony :), Glasgal doesn't seem to be around anymore. I just made a bunch of calls, first to the number in the catalog, then to toll-free directory assistance, then to directory assistance in New Jersey, with no success. I then did a web search on "Glasgal Communications" and found this on a stock market discussion BBS: "WE ARE MANUFACTURERS OF HIGH QUALITY EMPTY GLASS BOTTLES. WE PRODUCE BOTTLES IN TWO COLORS AMBER & WHITE. WE ARE SUPPLYING TO THE LIQUOR, PHARMACEUTICAL, FOOD BEVERAGES AND COSMETICS INDUSTRIES ALL OVER THE WORLD." So either Glasgal Communications has radically altered its business plan or some new company has commandeered their name. If you run across a Glasgal Communications catalog from days gone by, grab it. This also applies to old Black Box catalogs (whom still exist) because if their old catalogs have the same format of their current catalogs, you can expect the same type of helpful information.
