Hi Tore I would suspect that there should be a label stating the input voltage range. If not, use a transformer. You might also look inside. Many switcher supplies had jumpers to select input voltage. Dwight >From: "Tore Sinding Bekkedal" <toresbe(a)ifi.uio.no> > >I may (or may not) get an Osborne 1 soon, but it's rated for 120v.

Osborne 1 Voltage

by Robert_Feldman＠jdedwards.com

The O1 can be switched between voltages. The procedure depends on how old it is. Check out the information on pp 31-32 of the "Osborne 1 Technical Manual" at http://www.spies.com/~aek/pdf/osborne/osborne1TechnicalManual.pdf.

Compaq Deskpro 286

by Bella.Oxmyx＠charter.net

Does anybody have a listing of translations for the drive types for a Compaq Deskpro 286? (i.e. type , cylinders, heads, sectors) I have couple of hard drives I'd like to add, but can't tell what drive type to select. The setup disk doesn't have a user definable type. Jack

I don't think I'd run it too long without the capacitor increase. They run the motor hot at 60Hz. It'd be even hotter at 50. Dwight

JetDirect EX print server

by Robert_Feldman＠jdedwards.com

I believe I have one at home. I'll check tonight and let you know tomorrow. Bob -----Original Message----- From: chris [mailto:cb@mythtech.net] Sent: Thursday, June 12, 2003 3:16 PM To: Classic Computer Subject: JetDirect EX print server I'm not sure if this is older than 10 years yet, but people on this list have a library of manuals, so I'm asking anyway. Does anyone have a manual to an HP JetDirect EX print server device? Specifically model number J2382. I'm trying to find out how to default it to factory settings, and how to get in and change configurations. Holding the TEST button on power up doesn't seem to do default it (or if it is, it isn't clearing the error condition, but that might also be because it isn't taking the BootP info for its IP address). I have two doing the same thing, and I tend to doubt both are broken, so I'm guessing that the manual HP has on their site for the EX Plus doesn't have the right directions for it (not too surprised). So, anyone have that manual? -chris <http://www.mythtech.net>

cctalk digest, Vol 1 #642 - 31 msgs

by alhartman＠yahoo.com

Sorry you both had problems with Stewart. I've known him for over 20 years now, and never had problems like this. I'll ask him about it. I'm pretty sure the items ship from State College, PA and he lives in Brooklyn, NY. So there's some quite large physical distance between he and where the shipping is done (about 5 hours or more by car). I know he can be a little funny about selling large quantities of things. I've tried to set him up with people to buy large amounts of software, or to license his software that he isn't selling anymore only to have a perfectly sound deal fall through. I guess he feels if he holds out, he'll make more money selling it piecemeal overtime than selling it discounted in a lump. I'd also guess he really WANTS a slow income stream, rather than a large lump sum for tax purposes, and to have that steady income coming in. I don't know. I live in Philadelphia, PA now and only talk to him once or twice a year. He hasn't come to the Trenton Computer Festival in two years now. Since getting married, he's been busy with other things. If I get any answers, I'll let you know. I CAN tell you he isn't a crook... If anything, he's been abused by thieves quite a bit over the years I've known him... But, he is definitely an honest guy. He's NEVER ripped me off in the 20 years I've known him. He's always been fair, honest and generous. Not knowing the details of your deal from his end, I can't comment on what happened. In these kind of things, there are always three sides... Your side, his side, and the unvarnished truth.. LOL! I hope you don't feel harmed in any way. You can tell I like him a lot. He introduced me to some Personal Improvement work over 10 years ago that literally "Saved my life". And so, I have a rather large soft spot for him. But, given that... He is still an honest guy. I'm sure he wouldn't purposely rip anyone off. He might dissappoint someone by screwing up, as humans are wont to do... But I can guarantee it wasn't a purposeful rip-off. But, I have no problem with any one reading about these two dealings with him deciding they don't want to buy anything from him. There are plenty of Timex items on eBay. You can go anywhere to get this stuff... I have a few odds and ends I might get rid off (like a Thermal Printer), but I'll keep my ZX-81... If only because I built it with my own butter-fingered hands.

Substitute for DEC SS/QD Floppies

by skidmore＠worldvenue.org

I am looking for blank disks to use in a DEC RX50 drive. I have seen posted several places that DD disks can be used, but so far my attempts to initialize Verbatim DS/DD disks under RT-11 have failed: "?DUP-F-Size function failed" Thanks, Barry -- Barry Skidmore <skidmore(a)worldvenue.org>

Looking for schematics for DEC M702 and M720 modules

by erd_6502＠yahoo.com

Both of these are likely to be labelled "memory detection". I have seen both appear in module listings (and, from reports, in the real world) in slot B10 of a PDP-8/i. I keep entertaining delusions that I will be able to upgrade my -8/i to 8K someday. This module is the only one that I cannot borrow from another machine or my pile of spare parts. ISTR the M702 contains a delay line and some buffering TTL. I'm told that the M720 contains some TTL chips and a few transistors. My goal is to understand them well enough to fabricate a substitute, either from scratch, or by co-opting some blank spaces near slot B10 and using DEC M-series modules. Thanks, -ethan
