I do have a 12966A BACI interface in my 2117F, but unfortunately no interface cable for it (or for any of the other interface cards in the system). Anyone have a spare cable for some sort of reasonable deal? -Glen >From: Bob Shannon <bshannon(a)tiac.net> >Reply-To: cctalk(a)classiccmp.org >To: cctalk(a)classiccmp.org >Subject: Re: HP 2647A / F Terminal >Date: Mon, 21 Oct 2002 17:22:21 -0400 > >The HP1000 264x boot rom uses a common BACI board.

Reading floppies under Linux

by eric＠brouhaha.com

After that thread about reading various floppy formats under Linux, and I went to the trouble of packaging up a prerelease of dmklib, releasing it on SourceForge, and announcing it here, I'm somewhat disappointed that no one has downloaded it. I was hoping for some feedback. Sigh.

HP9100 Calculator

by martin.kaeser＠auge.de

Hi all, i bought a HP 9100 A calculator and need some advice. According to the owner, the power supply hummed and the backlighting came one - nothing on the screen, though. I think i should test the power supply and the tube first. Any suggestions on where i could test voltages and what i should get? How long would the screen take to light up? If the calculator is stuck in a loop, would there be a display at all? Would pulling the logic cards first be a good idea? Thanks for advice, Martin

Naming Computers [ was: Re: A Momentous Decision ]

by carlos_murillo＠epm.net.co

I started with mountain names (heck, everyone does, but then I *really* like some mountains). But I tried to use original names whenever possible (citlaltepetl, popocatepetl, iztaccihuatl, jimulco). Then I followed with aztec deities (coyolxhauqui, chimalpopoca, tezcatlipoca, huitzilopochtli...). Nahuatl language is just great for naming hosts.

Computer names Re: A Momentous Decision

by mtapley＠swri.edu

>Just out of curiousity, how many other people here name their classic >computers (for reasons other than giving them a network address) Once I've worked with a computer enough, I name it. Classic or not. That probably contributes heavily to my resistance to replacing them with newer models. - Mark

Someone was looking for a Packard Bell power supply

by cb＠mythtech.net

A while back I was talking with someone from this list about a Packard Bell power supply they were looking for. We decided that the one I had wasn't the right one... but just a few minutes ago, I stripped a Packard Bell 486, and have its power supply. So whoever that was, if you are still in need of one, email me, and we'll see if this one fits your case. -chris <http://www.mythtech.net>

DEC wiring colors and the PDP-8/e PSU

by erd_6502＠yahoo.com

I think I have repaired the circuit breaker in my PDP-8/e, but in my efforts to reassemble the dismantled breaker, I am concerned that I might have swapped the hot and return wires (black and white) from the mains plug. For internal AC wiring, I have seen in this power supply and others (of the -8/i and -8/L vintage, among others) white and red wires. Is it white-to-white, black-to-red? The problem with my breaker turned out to be curable by tightening up the pivot points of the double-jointed contact-throw mechanism. The design, it seems, depends on the back-pressure of the movable contact into the fixed. One breaker stayed extended, while the other collapsed before the throw was complete. As there is a linkage that trips both at once, that's all it took. I think there was excessive side-play that meant the weaker breaker couldn't stand the pressure at the main joint and it popped. Before disassembling it, the symptom had been that I could reset the breaker dozens of times in a row and never have it stick. Now, it seems quite mechanically reliable. Haven't applied power yet, for obvious reasons. Thanks for any tips. If anyone happens to have their PSU dismantled enough to see the back, I need to know which half of the breaker, white-lead or black-lead, attaches to the lone white wire, and which one attaches to the red wire (with a companion wire). Thanks, -ethan __________________________________________________ Do you Yahoo!? Y! Web Hosting - Let the expert host your web site http://webhosting.yahoo.com/

Favorite terminal

by emu＠ecubics.com

Hi, what is THE favorite terminal you folks here use ? Now I have all this nice VTxxx I ever wanted, but they always miss the graphics capabilities, I had on my terminals in the office. (not talking about GUIs, just few nice lines on the screen) So, is there something like emulating VTxxx (52,100,200,320,340) and tektronix ? (probably even 38400 baud ? I really like to talk about terminals, not software for PC's emulating those ... cheers & thanks
