Top 10 Holy Grails of Classic Microcomputer Collecting

by kaikal＠MICROSOFT.com

Whoops, Holy Grails of Classic PERSONAL Computer Collecting :) I only put in "Micro" to leave out the PDP-1's, etc. -----Original Message----- From: Doug Yowza [mailto:yowza@yowza.com] Sent: Monday, October 05, 1998 4:14 PM To: Discussion re-collecting of classic computers Subject: Re: Top 10 Holy Grails of Classic Microcomputer Collecting On Mon, 5 Oct 1998, Kai Kaltenbach wrote: > 2.

Aquarius Data Recorders

by kaikal＠MICROSOFT.com

Well, my whole Aquarius only cost $35 with mini-expander and 3 carts, so I guess I'd go maybe $10 on a tape drive. Kai -----Original Message----- From: David Williams [mailto:dlw@trailingedge.com] Sent: Tuesday, October 06, 1998 1:50 PM To: Discussion re-collecting of classic computers Subject: Aquarius Data Recorders I just received an email from a local group which has 250 new in box Aquarius cassette recorders. They are taking bids but I suspect you can't just buy a few but would have to take the whole lot. I have one but could use at least one more and maybe two and it would be nice to have the box and any doc or cables. Is there any interest in this out there? If so, how much would people be willing to pay? Don't forget shipping costs. Let me know. BTW, "local" in this case is Houston, TX. ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

Are you arguing that the 8080 is not a microprocessor? Where did you get that idea from. It's a the idea that CPUs don't have to be single chip to constitute a microprocessor/microcomputer. The rest is stirring the pot to hear it clang. Allison

< Don't you mean 1801R and 1801S? My early 18xx book doesn't list any 181 Both. Mine do, I have an unusual collection of RCA data books with alot of their loose data sheets as well. I used to call on the RCA microcomputer systems group down Somerville NJ. Allison

Same for me, but if we follow the ongoing thread, it will be visible, thats it's less about whats the first of wich ever (unclear) kind, and more about vague concepts and the impact of a certain design. All this firsts and this-but-not-that things operate at borderlines where are no real borders. Maybe there is a 'Uncertainty Principle' of certain 'seem to be exact' terms. Like ordinary physiks, they are usable for every day life, but when (we are) try to define the very finest structur, we have to discover that they are no more usable. Gruss H. BTW: should I call it Frankes Uncertainty Principle of Computer Terms ? (SCNR *g*) (I meet Werner Heisenberg once in 1972 at a speech at our school - quite an notable man.) P.S.: I like Sam's point about regarding unpretended tasks AND is like Doug's idea about (technical/comercial) impact. Both have their advantages and disadvantages, but none can either be used as this blade everybody wants to have, since there is no strict this-or-that. I think both are to be considered. A concept without without follow up is not relevant, and if we only look for the (comercial) impact, so anything beside the x86 wouldn't be woth to be remembered ??? The true worth of this list is NOT to get this-or-that thing, it's about aquiering and enhance knowledge on all regarding fields, ideas, concepts, etc. -- Ich denke, also bin ich, also gut HRK

< > So would it be possible to come up with a group sanctioned list of < > definitions for: < > computer (generic) < > digital computer < > analog computer < > minicomputer < > microcomputer < > processor < > microprocessor < > mainframe Pick up a dictionary and use it! These words have a definition that works if used concisely. Then we also need to get group santioned english. Part of the problem is these are exacting terms that are often abused linguisticly. After all it's easity to say X is first computer. Only to be corrected because you didn't say analog, digital, mechanical, electrical, relay, vacuum tube, transistor, integrated circuit, RTL, TTL, ECL, MOS, CMOS, ad infinitum. If this seems nitpicky consider this statement; The norden bomb sight, an analog mechanical computer has it roots in what? If that appears to be an exercise for the inane we are preserving, using, trading, collecting and otherwise dealing with history and in archeological terms what, where, when, who, how are other questions are part of the story. Accuracy and minuniscule details are the essence of an industry that in my lifetime went from the early commercial vacuum tube machines to the 64bit CPU chip running some thousands of times faster.

< Historical footnotes are always intresting, but it seems to me that to < pronounce "the F15 CADC was first, not the Intel 4004" is a strawman. W It is if you leave it at first and don't get any more specific than that. the F14 CADC was the first microcomputer system that made fly by wire practical. The 4004 was the first commercially viable single chip CPU. Clear statments that do not conflict but do make a statment that points to their significance. < I'm not denying that Holt produced a CPU, and it may be important in th < history of military computers. It is irrelevant in the history of the < personal computer unless there was a personal computer designed that < included it or a direct descendant. Or the technology that made the silicon possible for later commercial designs. It doesn't have to be the same design. < I think it's great that Holt got his story out. Footnotes always add < depth, but no chapters need to be rewritten. The assuption is they are accurate chapters. ;) the depth is needed to see how the later chapters are significant. Allison

As I get deeper into collecting there are systems and docs I'd love to find. Ten of them in no special order. 1. Cincinatti Millichron 2000, 2100 or 2200 based mini. 2. Docs (or copies) for IMSAI IMP48 3. Intel MCS-8 4. Control Logic modules L series (for 8008 based system use). 5. and 8E/F/M or programmers pannel equipped 8A 6. Signetics 2650 based SBC 7. Intel prompt-48 9. DEC 8008 based SBC. 10. RCA 1801/18101 based system eveluation board. (1801 is not a typo). Allison
