Updates

by bill＠booster.bothell.washington.edu

Hi all. A lot of things have been significantly updated over the last few weeks. You may want to take a look. The web site (http://weber.u.washington.edu/~bcw/ccl.html) has been reworked somewhat. Brett's Classic Computer Encyclopedia (http://www.xnet.com/~danjo/classic/index.html) has grown quite a bit but could use some images (hint, hint, guys) Isaac's Classic Computer Rescue site (http://www.comland.com/~idavis/classic/classic.html) is looking good. The Links Section of the web site has nearly doubled (although I know you guys have more that you could cough up ;) Same with the FAQs section (once again - send me more) and the ClassicCmp FAQ has been HTMLized for your ease of reading. The document archive is online (although most listings are still being held under review). The Big List of Classic Computers now contains sections for Prototype and Limited-Run computers and for computers which more info is needed on. The FTP site has been indexed and divided up into sections for various computers - not a whole lot is there, a few faqs, articles, and pictures. Feel free to send more ;) (ftp://140.142.225.27/pub/classiccmp) Bill ---------------------------------------------------- Bill Whitson - Classic Computers ListOp bill(a)booster.u.washinton.edu or bcw(a)u.washington.edu http://weber.u.washington.edu/~bcw

HP 9836, HP 86 ??

by ard＠p850ug1.demon.co.uk

Aka IEEE-488, and very similar to HPIB (= Hewlett-Packard Interface bus). HP were the company who designed it, but it turns up on all sorts of machines. It's an 8-bit parallel interface using a 24 pin connector. 8 pins are ground, 8 are data, 3 are handshake, and 5 are bus control/management. It was originally designed to link up lab equipment (DVMs, counters, digital 'scopes, etc), but HP use it as a general peripheral bus (disk drives, plotters, printers, etc) on some of their micros. Commodore used it for much the same purpose (although with looser timing requirements) on the PETs > David Williams - Computer Packrat -tony

HP 9836, HP 86 ??

> There are two flavors of HP 86, the 86A and the 86B. Thanks for the info - I've only used 86B's. > Re: the 9121: yep, single-sided Sony stiffy drives that hold about > 300KB I think.

Probalby 320 or 360K bytes (at least on the 150 - is the 9121 supported on the 150 - my manuals are silent on the subject...). It's 80 track single-sided, and thus the same size as a double-sided 40 track disk. > You know how 3.5" drives open the metal slider so they can get at the > medium?

I've also seen disks that open automatically, but stay open when ejected. You 'pinch' them to close them. They did not close automatically on ejection from any drive. > -Frank McConnell -tony

PDP performance question.

> what is a PDP? choices 1,4,5,6,7,8,9,10,11,11/780,11/750,11/730? Got something against the PDP12 and PDP15, then ? :-) [Sorry, couldn't resist it!] > Allison -tony

by strzecha＠kis.p.lodz.pl

Hi, Yesterday I recived Thomson To7-70 computer, which is totally dead. When it's working, on display there are only horizontal color lines, each of them has witdh of one character. Is ther anybody who can say me whots's bad. I suppose this can be demaged processor (it's incredibly hot after 2-3 minuters of working), but I am not sure. Thanks, Krzysztof Strzecha

PAM computer, Convergent?

Like I said, "bogus price". I didn't buy it. I didn't even inquire at the counter. IBM-compatibles (and I think these were fairly so) aren't real interesting to me even if George Morrow did let his name get put on 'em. (Though I do have one of the Osborne 3 flavor...a moment of weakness I guess.) BTW, speaking of Morrow stuff, I met a guy at the Foothill swap meet today who was selling a Micro Decision (claimed to be an MD-11 but two floppies, no hard disk) for $30. I'm not interested -- got two of 'em that I haven't touched for a while -- but thought someone here might be. Has software and manuals but I did not see the big stack of paper-bound manuals that I might expect; the seller said he got it >from an ex-Morrow employee and it may have been assembled from excess parts but is functional. Other stuff found at the Foothill swap: Sinclair ZX-80. Well, it's in pieces, but board, case top, case bottom, wall wart...yep, looks like they're all there. $5. First one I've seen in years so I snagged it. A couple of S-100 bits. Some HP employees were perturbed by the prices of quality S-100 gear and so set about designing their own, and it looks like they got to use HP's printed-circuit production facilities. Apparently I missed the chassis but got the junk box for another $5. Included are a pristine blank CPU board of their design, as well as a couple of S-100 bus terminators. S-100 bus terminators with the HP logo, whodathunkit? Part number on the board is 7373-60003, and the board comes with helpful instructions in the traces (no solder mask or silkscreen): TERMINATOR THE LAST BOARD I think there is a story here, and I want to know more of it than I got today. Convergent Tech Workslate, plus printer and serial/parallel box, condition uncertain. $26. Pricey but if I get it cleaned up and working it could make a nice desk toy at the office. What sort of power input do these things want? Xerox 820 board, socketed but ICs not plugged in. Another project that the owner lost interest in. $2. -Frank McConnell

What exactly, is an IBM System 36?

by spc＠armigeron.com

I have the oportunity to aquire an IBM System 36 model 5364 with manuals and operating disks, all in working condition. My question is, I have never heard of this system (the 360/370, yes). What can I expect? Secondly, from the same source, I can get a Compac Portable I XT with harddrive and memory upgrade, ethernet 3/comm and AST 5250 emulation (some mainframe terminal?), again all in working condition, but from what I hear, it's portable in the term that yes, you can lug the entire setup. Third, for anyone that is interested (you pay shipping, plus maybe a few extra bucks - whatever you think it's worth) the following are also available: 10M HD for an IBM 360 Monroe (possible) "bookkeeping machine" Underwood typewriter (manual) (unknown) manual adding machine I'll be hearing more about this stuff on Monday. -spc (Is getting more stuff than he knows what to do with ... )
