Calculator displays

by allisonp＠world.std.com

Nixies are also not a generic term; it's trademarked by, I believe, <Honeywell. When other manufacturers made similar displays (sometimes <incadescent, even) they were called "Numerons", "Numatrons", "Decatrons" <and various other terms. Quite often these displays were more dissimila <than similar, to tell you the truth (there were probably patent issues <involved in addition to trademark issues.) Yes patent issues and different drive methods. The decatron or Numatrons I forget which had 10 pins around the permimiter that would glow ehn active and there was a steering electrode to force a "shift up" or "shift down". They took advantage of the hysterisys of Neon gas displays (turns on at higher voltages than turn off. There was also a dot matrix display by burroughs "self scan" I have a 32 char version. Allison

Classic prices at eBay...

by mor＠crl.com

Man things over on eBay are getting hairy. A Sol-20 and IMSAI 8080 recently went for over $600 ea. And the Sol-20 may not have sold because the seller's "reserve price" was not even met... Currently there is a MITS Altair 680 at $1,825 and an Apple Lisa at $500, both with over 2 days to go until the deadline. Oh well, it's back to the old thrift and scrounge circuit for me. -- mor(a)crl.com http://www.crl.com/~mor/tps/

Support for obsolete products

OK, help me brainstorm arguments to persuade companies to release obsolete information. Certainly pointy-haired managers (does the cartoon "Dilbert" cross the pond?) will opt for the simple safe solution of "don't let anything out of the office, or out of our control". And there's the question of money to be made. As soon as someone seems interested in old technology, they'll believe there's still some money to be made. Then there's the question of the cost and trouble of drafting or approving any legal document to make the transaction official. Why spend money on giving away products? - John Jefferson Computer Museum <http://www.threedee.com/jcm>

Low-end Unix (was: TI99: Anyone reading this with a TI-99/4A?)

I have heard tell (from a very reliable source) of a version of Unix written for the Radio Shack Model 100 (8085, 32K max). (And no, it's not available, and yes, he's tried to get the company that did it to release it.) I thought someone had said that CP/M was based on Unix?

Fwd: 75 lbs of DEC Ultrix manual for free

by Mzthompson＠aol.com

Found on comp.sys.dec - if interested please reply to the originator - webdolphin(a)my-dejanews.com This amounts to around 20-25 three ring binders, and is good information on Unix operations, processes, and commands even if you don't have Ultrix. Mike ------------------------------------------------------ Subject: 75 lbs of DEC Ultrix manual for free From: webdolphin(a)my-dejanews.com Date: Thu, May 7, 1998 15:59 EDT Message-id: <6it0a3$gki$1(a)nnrp1.dejanews.com> Hi all, Anyone interested in a complete set of Digital Ultrix manuals dating from 1990/1991? I am assuming they are complete, given a lot of them are still shrinkwrapped. Email me with your physical address with a Fedex or UPS account number if you want the stuff. Otherwise the box is going into the dumpster come next Thursday. Allister

the new Apple iMac

by allisonp＠world.std.com

<Actually, if I were to design a computer, I would consider not <including a floppy drive, or at least making it so that it doesn't <depend on it. I have six VAX computers and NONE have floppies. Why, becuase even 1.44mb floppies make sense in that environment. Since they have tapes and are networked together floppy is of little use. With the size of applications and all a writeable CDrom or a ZIP disk makes more sense than floppy. Further, I'm working on a z280 design and am seriously considering no floppy. Why? Eats power and space for intermittent use at best. I'd rather use a utility I wrote years ago to transfer files via serial port (back when no two machines had the same format or size floppy). I even intend to put the whole OS and then some in EEprom as it's cheaper and faster that floppy or hard disk. Allison
