Yes, I agree with that one.

But by that definition _none_ of the micro PDPs were true microprocessors, or at least none up until the 73. The Micro J-11 processor in the 73 was implemented as two chips on a large ceramic carrier. Was this also the case with later J-11s? Philip.

RL02 ID number button

by wanderer＠bos.nl

Hello All, Well, I got my old 11/24 back which I did give away a couple of years ago and also found an 11/34 and form another person I can get 2 more RL02's. Are there any PDP users using Xenix, or only Unix (V5/6/7) ? and Oracle V2.3? One of the packs might still have this on it. Does anybody know where to get the number buttons (specifically #2 and #3) for the RL02's, so I can use my extra units as such, or is there another to let the units know that they should not act as unit #0 and/or unit #1? Thanks, Edward P.S. has somebody in Europe an RK05 or RK07 left over :-)

old AOL disks

by SUPRDAVE＠aol.com

i have several aol versions starting with 1.5 as ive never seen 1.0 anywhere. i believe quantumlink/pc link basically turned into aol. i *think* applelink was the same or close to it. as of last year, aol 1.5 was still supported and mac aol 2.5 still works, if only for email and file transfers which is what i use it for. david In a message dated 98-06-29 13:33:09 EDT, you write: << This isn't quite classic, but classic enough. Does anyone have old AOL disks they could e-mail me? Any version before 3.0 for the PC. BTW, when was AOL 1.0 released? Wasn't AOL PC Link before? A program called QuantumLink came with my Commodore a few years ago, and when I called the tech number to see if they're still around, I was forwarded to AOL. >>

1st Mac

Well, when I read the want ads, I see Mac SE/30s going for $300 easy ("Good first computer", "Good student computer", "Served me well"). Those ads really last from week to week... >As far as worth, well i've seen them on ebay go anywhere from $75 to over $200 >depending on what ancillary stuff it had (orig docs, packaging, etc).

Zuses (Was: Re: Overhyped Innovations (was Re: OS's In ROM'

> I didn't think they were jokes (;) and he did have a child, I just don't > remember what gender. But to bring this thread on topic, could someone > tell me what the Zuse computers did, and what Zuse models there were. > How big were they? Has anyone seen one? Do any exist now? Big ? Hmm. The Z1 could be described as a desktop computer, since Zuse (and his friends) bulid it on his parents kitchen table - but it tool up the whole table. Thru wartime tjhere have been 4 Models - Z1..Z4. After the war I think somewhat like 40 or so designes, and some of them had quite some success. The Zuse company did some very unique computers some of them even part analogue and part digital. They also did the first computer generated graphics not only in science lab, but also sold drawing/cartography equippment. They also had the first plotter running. And sold them. Also some early CNC installations are credited to Zuse (Beside that he in fact designed the first process controlling computer ever - for production of V1 cruise missiles) Eventualy SIEMENS bought Zuse in the 60s. Some exist sill - i.e. a reproduction of the Z1 in the Museum fur Verkehr und Technik in Berlin, or a Z3 in the Deutsches Museum in Munich. I don't know if any of the later (after Z11) 'usual' machines survived. Gruss H. PS.: Zuse also aquired some patents in the 50s for his ideas about the Feldrechenmaschiene (field calculating engine) - early ideas for parallel processing and still base for a lot of newer designs. P.P.S.: Try http://www.histech.rwth-aachen.de/www/quellen/Histcomp/Zuse.html for a nice lifetime/development story. -- Ich denke, also bin ich, also gut HRK

More questions, then: What did they do? I guess they couldn't have been that powerful if the ENIAC took up a whole building... >Big ? Hmm.

Nice story beside: Kaufhof (a big department store group in Germany) once delivered a simple dektop program, using the same working room metaphor as Bob, with all their PCs (88/286/386). Junk, but some strange guys at SIEMENS PN (telephone systems) choosed this program as desktop for their new service PC system. They thought this thing would help the _proferssional_technicans_ to deal with that system ... rotfl. Its still in use, but soon after first tests this office thing dissapeared and only some full screen windows with simple text/icon buttons remain ... Almost like the win 3.1 programm manager ... strange huh ? Gruss H. -- Ich denke, also bin ich, also gut HRK
