John, Nope. I'm running mine on a standard 3-conductor cable, 12AWG. It draws between 700 and 900 watts, depending on if I insert a full complement of memory (8MB) and the FPU. - Matt At 01:04 PM 9/15/2002 -0600, you wrote: >Do these things require (as I have heard rumored) 240-volt 3-phase >power? > >Thanks >John Matthew Sell Programmer On Time Support, Inc. www.ontimesupport.com (281) 296-6066 Join the Metrology Software discussion group METLIST! http://www.ontimesupport.com/subscribe_t&c.html.

Hp-85B is really an HP-85?

by fastluck＠email.com

I purchased 4 HP-85Bs at auction yesterday. I was browsing information on HPs at http://www.finseth.com/~fin/hpdata/serial.html, and discovered that one of my "new" machines was manufactured in February, 1982. That's 16 months before the 85B was released, as I understand it. Here's the serial number: 2210A60158. If the first two digits are the number of years since 1960, it was manufactured in 1982. If the next two are the number of weeks since a certain week in November, it was manufactured sometime in February. Is that right? If the HP-85Bs were released on June 1, 1983, this one was either a prototype that rolled off the 85A assembly line, or it's an 85-A in disguise. Do the 85B covers fit the 85A? If so, there's a hapless soul with an 85B that thinks it's an 85. And I own both models. Something else that's interesting: This particular model had an older-style riveted-on serial number plate, while the other three had newer stickers. It s also the only one with a 82936A ROM DRAWER. This drawer has the 00085-15002 PLOTTER/PRINTER ROM. I don't think that's significant, but maybe?? One other thing: The FCC-ID on three models ends with 85B. The model in question either hasn't got one, or I can't find it. If you can shed any light, please do so. I plan to keep one and sell off the other three. If I'm selling an 85-A, I want to make sure that's what I'm advertising. In fact, I may just want to keep two of them. Also, how much is an 85-A worth? I can't find them for sale anywhere. Cheers, John

HP CS/80 Instruction Set Programmers Manual (5955-3442)

by steven_j_robertson＠hotmail.com

Glen, Earlier this year I wrote a primitive driver so that my HP1000's could talk to CS/80 drives. Even with the CS80 docs it took weeks of tinkering to make the damned thing work. The CS80 protocol really isn't that difficult. All you need is a HPIB protocol analyzer (Joe has one) and some patience. I can help you get started with the command sequences. Getting the HP1000 to to send all the correct sequences is a much larger problem. I never finished the project but, I can do some basic disk functions. I can boot from the 1000, I can read an write absolute sectors, and I can run progrmas from the disk. This in itself is a major accomlishment. If you need any help getting started, just let me know. See ya, SteveRob _________________________________________________________________ Send and receive Hotmail on your mobile device: http://mobile.msn.com

It's basically a pocket version of the CC40. It's possible to adapt a CC40 Hexbus cable and peripherals to it, even, according to the article. http://www.hightechsolutions.com/Accesories.htm for TI-74 and 95 stuff. They appear to be out of the computers, but the PC-324, modules, and other accessories are available. jbdigriz

EIA 232 vs. 422, Color Computers (was Re: Serial floppy drive s)

We gave up and decided to build a device to simulate bit errors. > Hi Jeffrey What makes you think that wrapped on the outside of a Jacob's ladder has either the right coupling or the right frequency spectrum to effect a RS-232 signal? Arbitrary test like this are not real world test and only impress those that don't understand what it takes to interfer with a particular signaling method. There are books written about how to test for interference. Looking at impressive sparks will sell P.T. Barnum's "one every minute" but not me. The environment I used the RS-485 in had RS-232 running at 4800 baud and was seeing error burst on the order of 1 in every 1000 or so bytes. The lines were not any longer than 20 feet. It was more the type of noise source that was important. One needs to know the right spectrum and how the energy was coupled. I wouldn't have expected the Jacob's ladder connected as you described to have introduced hardly any energy in the right form. Dwight

IN BAD TASTE: Putting the blame where it belongs?

by Innfogra＠aol.com

And here I am contributing to the way way off topic..... I understand one of Tom Clancy's novels deals with the subject, flying large airliners into a building. Written in the mid 1990's. I am trying to find out which novel it is, he is very prolific. Paxton Who is looking for a novel to take traveling to Fiji and wondering where he will find the internet there? Hmm.. When I was last there (1990) the telecom system was run on intel multibus and the airport on a microvax. Does that make this on topic.

I'm 50 miles n SFran. Decision in console, this thing big raw box approx. 3x2x1' only smaller, what is it, who can I contact who is the prime collector etc.?? It has been in covered storage for years and I haven't looked at since. I am writing you to get some measure of its value and being sought after. thanks, wally _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com

CP/M-8000

by jurjen.kranenborg＠philips.com

Dear Christian, On 10/15/01 you wrote, concerning CP/M-8000: Hi, I've got a Olivetti M20 Z8001 PC, and it appears that once there was a CP/M-8000 version available for it. Has anyone got such thing? I'd be interested in this, I could swap with some PCOS programs. (Assuming the copyright holder (Olivetti) doesn't mind.) regards, chris In case you still are looking for it, here's the link to the officilial DR distribution of CP/M-8000 tuned to the M20: http://www.cpm.z80.de/source.html On this page you will find the link to CP/M-8000 distributions I have a few questions concerning the z8001 and accompanying software, may I get in contact with you about this (I am planning to build a Z8001 system myself (in the year 2002? Yes, because I bought the parts in 1985 and I rediscovered them just recently) Regards, Jurjen Kranenborg
