I got a TI 58-c calculator a while back but there was no transformer with it... I was hoping someone would have one and could give me the specs on it and if it plugs into the calculator in either rotation... thanks, bob laag

Lookee what I just got!

by wizard＠voyager.net

Hello, Jay, especially, but any other HP types, Well, I went and did it. I am now the proud owner of an HP-2117F, if I can identify it correctly, shown here: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320067174880 ... and, FPU, shown here: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320067174671 My experience with the HP 1000 series machines is, almost exclusively, programming them in TSB on HP-200B, C, and F systems, many moons ago. Jay, you seem to be an alpha geek when it comes to HP iron. (A term of respect, no offense intended...) So, could you look at the above auctions, and tell me what I need to make a good system. Obviously, a disk system comes to mind... but, if you could be specific, I would appreciate it. Also, what are the chances of this being a suitable machine to run Time-Share BASIC, or TSB? I imagine I would need microcode boards or ROM for the microcode boards already there, but, for all I know, it already *IS* a TSB machine. Thanks for your consideration. Peace, Warren E.

wall wart for TI-58-C

In other words, the above AC adapter is for a TI-59 ca. 1979. It shouldn't matter which way it's connected, because it is an AC adapter. Inside the battery compartment of the TI-59 you can see the four diodes of the bridge rectifier. Jeff Walther

DEC beige/creame/white paint

Chuck Guzis wrote: There used to be a "rattle can" textured finish that deposited various-sized blobs of differently-colored paint. I wonder if this might be a close texture (used as an undercoat). When repairing fiberglass-resin cases, a bit of foam rubber (such as that used to pack old hard drives) works pretty well for giving things a fine texture. Cheers, Chuck ----------------------------------- And these days, you can get a spare can of almost any texture you want at Home Depot or Lowe's. I've tried some of the "orange peel" with good results to match the old crackle texture. I agree it's not the best but it is hard to pick out without very close examination. So far, no problems with it coming off either (knock on wood!) Billy

Archiving workstation hard drives

by ken＠seefried.com

[catching up a bit] > Ideally though you're going to need to determine the model of HD, and get > some extras. Ideally, yes, but I've found that's not always required in practice (in admittedly limited experience). I've successfully dd'ed a couple of old SCSI drives to larger SCSI drives and was able to boot & run without issue (other than the wasted space). I suspect it works because SCSI hides many low-level details. I certainly didn't test all the boundary cases, so there certainly might be gotchas if you used the duped disk extensively or in production. On my VME532 machine, I dd'ed the ~150MB Maxtor ESDI drive to a ~300MB Maxtor and it boots fine from the larger, half-wasted drive. I wouldn't count on it working with another vendors drive, or for all permutations of ESDI controllers. YMMV. Ken

Does anyone have a working Everex DC-2000 floppy-tape drive they want to part with? I checked ePay, but didn't find anything. Drop me an email and name your terms. Thanks, Chuck

Victor 9000 boot floppy, was RE: laptops and 5.25 inch floppy drives?

by aek＠bitsavers.org

> I've just uploaded scans of the Tech Ref and several other tech docs > to http://bitsavers.org/pdf/victor/victor9000 I just noticed that the figures are all missing in the tech ref. Most wouldn't matter, but the sector format of the floppy would be nice to have documented. Does anyone have the details of this (actual sync pattern, etc.)?

Hi folks, I received an email from an individual who is looking for someone to help fix their 8/E and possibly their paper tape punch unit. Yes, there is still an 8/E out there doing useful work -- well up until a few days ago, anyway :-) If you are interested, available, etc. send me an email to info2007 at parse.com and I'll put you in touch, and you can discuss rates etc. (I have various ISPs blocked due to excessive spam; +1 613 599 8318 9am to 9pm and leave a message if you can't get through).

wall wart for TI-58-C

by mtapley＠swri.edu

Bob et al, the plug is polarized, so I assumed there's diodes in the wall-wart. Mine (TI-59, should be same) is at home and I'm not, so I'm not able to give better first-hand info before tomorrow, but http://xgistor-echo.ath.cx/files/TI59/ has much useful info. I commend the TI59_PSU.zip file to you in particular. Let me know if you want measurements off of my wall-wart(s). I think I can arrange that.
