Let's get this straight: A) alt.technology.obsolete does not need to be created, it has been on the net for at least as long as I have (6+ months) B) The newsgroup is currently dead (except for the occasional spamming post.) C) having specific newsgroups is ok, but what if you want the open discussion of computers like we have here? I kinda get irked seeing Spectrum posts in comp.sys.cbm. But wouldn't mind on a mixed group, because I am in that mode when I am reading it. (sound logical?) So, again, the newsgroup (alt.technology.obsolete) exists now and has been in existence for quite a while and I suggest we put this good opportunity (and name) to use.

Computer Ind. Books

>From: "e.tedeschi" <e.tedeschi(a)ndirect.co.uk> >Subject: bibliography >What do you think of this bibliography? Have I missed any important book >on the subject? Please help me in making this a useful refence for >everybody to use, if you care. Thank you There was also one by COMPUTE! Books, the (Small?) Computer Wars I think the author's name is Michael Tomzyk. I have yet to find it (or many that you mentioned) Though I found Steven Levy's Hackers very entertaining! One interesting book my wife came across in a thrift store is: "The Compleat Computer" a compilation edited by Dennie Van Tassel. It was printed in 1976 and has alot of press clippings, cartoons, articles and anecdotes of the then blossoming microcomputer age. One nice bit is the transcript of the session between Eliza (the psychiatrist program) and Parry (the paranoid program).

Collecting old microprocessors (as opposed to Computers)

by bluesky6＠ix.netcom.com

Does any one here collect old microprocessors like 4004, 4040, 8008, 8080 etc? The oldest CPU type I have is an NEC 8080A. Still trying to figure out how to make use of it. The legs are pretty corroded (used to live in humid climates). I've a Z8001 too, paid more than $100 for it but never used. Maybe I'll find an Olivetti M20 one of these days... There's a UK company that used to advertise in the UK version of the Elektor 4-5 years ago. They advertised the TI9900, NS32032 and other odd CPUs. Ben

That would be the NEC 7220. It was also used in the DEC Rainbow graphics option; I've not seen a DECmate II graphices option, but I suspect it was used there as well. A friend of mine built a video card for an Apple ][ using the 7220. We could do 1024 x 780, IIRC. He was experimenting with it and a touch screen device (a flat glas plate to go over the monitor with transducers along two edges; it put a high-frequency vibration on the glass then listened for echoes) as a programmable user interface. We were using Microsoft F80 on the Softcard connected to 8" DSDD diskettes. When does it start being an Apple ][ and start being a CP/M machine? Oh yeah; we used a plotting library from a company called Tesseract. Anyone else used it? Roger Ivie ivie(a)cc.usu.edu

> >What is a Heath H8 worth? I generally see H89's go for $25 US at hamfests. *I* wouldn't tie up $100 unless it was lovely and I really wanted one. Of course...it's worth what you want to pay for it, as Jim says

Jr. Dragons?

by jscarter＠worldnet.att.net

It's been years since I fiddled with a PCjr. It has a self test, to activate press Control-Alternate-Insert. Can't remember the specifics of the self test though. I don't know if Lotus for the jr required a disk, but I have been told it came on two separate cartridges. At 02:35 PM 6/23/97 +0000, you wrote: >As such, right now I have 1 complete Jr with floppy drive, sidecar, and >128K mem expansion (I believe... hafta look at the chips & calculate the >storage) with an extra internal floppy drive, an extra motherboard, an >extra keyboard (neither are chicklet, and one has a few stuck keys) I think >there was a Lotus 123 cartridge with it (but I heard rumors that it needed >a disk as well?) and a basic cartridge.

Need source for...

by kyrrin＠wizards.net

In the process of getting ready to upgrade my RQD11 QBus/SCSI adapter to near-current level, I discovered that I need a source for a hard-to-get PROM. Specifically, one of two parts should do it. Signetics 82HS189 AMD AM27S281A I've already checked with the manufacturers and a couple of local distributors. Yes, I'll be looking for these on my upcoming scrounging trip, but it would be a Really Cool Thing if someone could point me at a source for them. Thanks in advance. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Sysop, The Dragon's Cave BBS (Fidonet 1:343/272) (Hamateur: WD6EOS) (E-mail: kyrrin(a)wizards.net) http://www.wizards.net/technoid "Our science can only describe an object, event, or living thing in our own human terms.
