I found this in a news-group. I've never heard of a MAC-8 before. The Bell Labs Technical Journal, Autumn 1997, p53 states: The first microprocessor designed at Bell Labs was the Mac-8, a general purpose 8-bit micro- processor announced February 17, 1977. The Mac-8 was designed in 5-micron CMOS, requiring 7,500 transistors in an area of 32,45 mm2. It was packaged in a 40-pin dual inline package and ran at 3 mHz, providing 0.2 million instructions per sec- ond (MIPS) in performance. Long ago and far, far away in another lifetime; I somehow acquired a tube of these chips. I've always wanted to get a minimal system going built around this CPU. However I have NO DATA WHATEVER on them. Does anyone, anywhere reading this have the necessary hardware/software tech data to allow me to build and program a small system built around a Mac-8 ????????

Altair Registry

by jpl15＠netcom.com

With the current foment and debate concerning the mechanics of free-market capitalism as applied to Our Hobby.. this is prolly on-topic. It has been suggest to me (privately) that I have reacted to David Freibrun's offer of a central Altair registry in a bitter and unfriendly way. Such was not my intent, though Freudians are undoubtedly nodding their heads sagely right now saying "JaJa, he only sinks he means dat.." For the *tone* of my message, I truly apologize. For the *content* of my message, I reiterate, a little more calmly, that I have no intrinsic problem with a centrally-maintained database of who gots what where. BUT... tied in to some of the concerns Doug has/is raising [not that I agree with all of it, Doug... :) ] I am really leery of providing personal info on a rare and perhaps desirably valuable item in my possesion.. which, in the case of my Altair, is not for sale or trade, and I'd rather it not be stolen, either. That's all I tried to say, and I guess I got huffy in the process. If such a list is set up and maintained well and seems trustworthy, I have no problem with listing my gear. David, I apologise if I offended you personally... again it was not my intent. Cheerz John

Where to buy Gorilla Banana printers?

by todd.osborne＠barnstormer-software.com

Anyone know where I can find a Gorilla Banana printer? I have searched all the "normal" channels. These things were so popular in the early 80's, I can't believe they have all disappeared.

Unix for 8080/Z80? [Re: WooHoo!! PC/XT Unix anyone?]

by edick＠idcomm.com

Well . . . CP/M "looked a lot like" the old OS/8, yet it wasn't. I guess it depends on what your goal is. With the CP/M, it was having a console protocol which was already understood by any unemployed DEC programmer so they could be put to work on the 8-bit micros. Because it was already a defined quantity, it didn't have to be too thoroughly documented, either. I don't know about OS-9. I never saw it on a 6809 though I did see it running on a 68008, which is quite a bit more processor. It didn't look too much like *NIX either.l Dick ---------- > From: Allison J Parent <allisonp(a)world.std.com> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: Unix for 8080/Z80?

IBM PC-JX (was: Reiability of wrong media)

by guerney＠uq.net.au

-----Original Message----- From: Fred Cisin (XenoSoft) <cisin(a)xenosoft.com> >How many know about the IBM PC-JX? It had 5.25" 720K drives! >Never sold in the U.S., just Japan and Australia? Hmmm ... never sold in the US....I'll not dwell on the obvious about collecting a load of JX systems that were used in some schools here and selling them on e-bay ;) Do you US collectors want these machines? I don't collect IBM PC's, although I did relent once and pay $A20 for a JX machine (IBM Model 5511 with 5515 monitor and 5519 expansion unit - made in Japan and all in black with a 3.5" drive in the main box and a 5.25" drive in the expansion box) that was in good condition. As I suspected, not a very interesting computer to me. If someone was prepared to foot the freight bill from Australia, I would be prepared to sell or trade it. I also would be prepared to look out for others and send them on. Same applies to real Aussie micro's like Microbees and not-so-real Aussie items like Dick Smith branded computers (which invariably were sold under other brand/model names in the USA). Trades are more interesting to me than sales - my main interest is roughly defined as "1975-1985 home micros". It doesn't matter how much money I got for this at auction, it wouldn't help me find a lot of stuff that seems available to you lot at your local thrift store! If anybody is interested, contact me by private e-mail. Just be prepared for at least a 3-month shipping delay, unless it is only a light item, or you can afford a hefty air-freight bill.

Unix for 8080/Z80? [Re: WooHoo!! PC/XT Unix anyone?]

by edick＠idcomm.com

This notion of cooking up or breathing new life into an old 8-bit model to run *NIX is probably a mite more than has been considered for one reason. *NIX tends to want to use virtual memory, without which many systems would quickly choke. The old CPM-capables don't support VM. A good reason for this is probably the lack of performance. regards, Dick ---------- > From: Tony Duell <ard(a)p850ug1.demon.co.uk> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: Unix for 8080/Z80?

See Minix for an example of that also V4 and maybe V5 unix didn't either. Also It's been done! UZI uses the total swaping model, IE: processes are swaped out of core to make room for others. Allison
