After swallowing DEC, I'm glad to see COMPAQ get swallowed. But my opinion of Hewlett-Backward isn't what it used to be, and I don't think we'll be buying anymore DeskJam printers or DesignJam plotters, as they are no longer honoring the terms of the service contracts they sold us. Any escalating replies should be mailed to me privately...

Nixdorf PC 05 / 8150.00

by pricomu＠compuserve.de

Is there anyone out there - who has a manual for that maschine or - who knows how to connect this maschine to an IBM- compatible XT or AT with the cable which was supplied with the PC 05 as there is no possibility to run other programs than those on the integrated modules (my provide HHC_BASIC vsn 1.3; CALCULATOR and CLOCK) or - who has any other information concerning the maschine?

It's IEC 320, which is in several parts; you probably want Sheets C13, C14, C19 and C20. I should point out that the current ratings used in the United States are different for those used in Europe. Also that the current rating depends on the type of cable, not just the connector. Many of the power cords built to the spec are rated at 5A or 6A (6A was the original spec for the common IEC 320 *connector* but it was uprated a few years ago) because the *cable* in them is only rated for that much. The ordinary connectors are rated for use at temperatures up to 65 Celcius, and are sometimes called "cold condition" connectors. The version with the notch (keyway) is called a "hot condition" connector, and in Europe it's still only rated for 10A. However, hot condition connectors are made of materials able to stand a higher temperature and are used for things like electric kettles. They're rated for operation at up to 120 Celcius. In the States the connector is rated for 16A (again, assuming the cable itself is rated that high). The original intent was not to provide a higher current rating but a higher operating temperature. It just so happens that things that get hot (kettles) tend to use a lot of current to do so :-) The third version has the three pins all parallel in the same horizontal plane (ie, 90 degrees around from the others), and is slightly larger. It's rated at 16A in Europe (and for 20A in the States, I believe) but only up to 65 Celcius. -- Pete Peter Turnbull Network Manager University of York

CoCo Xpndr1 (was: RE: Keep or assemble???

by zmerch＠30below.com

Rumor has it that David Woyciesjes may have mentioned these words: > It sounds like you would get more enjoyment out of building & using >it, rather that letting it sit and collect dust. If you're toying with >building it, I would say go for it, but keep all the packing and paperwork, >too. That helps increase the 'value'. > >I think it all depends on whether you plan on selling it, or keeping it. I >would definitely build & use it. [snippage, fore and aft...] I don't necessarily disagree with you, but the "reproducability" would be decreased once the kit is built... i.e. you can't [easily] scan the boards, or re-design them in AutoCad, etc... With this in mind, I was digging thru an old box of CoCo stuff I have and I came across (2) Xpndr1 expansion cards, 1 of which is virgin. A quick search of Google shows nothing about them... I've started re-designing the card in AutoCad (as if I didn't have *enough* projects ;-) with improvements. Some are minor, like putting the signal names on the top of the card instead of the bottom (so it's easier to see the signal names when I attach a small breadboard to the top of the card...) some are major (or going to be) like the extra room for standoffs so it'll be self-supporting, and also connector ports for both a "PC hard drive power port" and a "PC floppy drive power port" so you can power the thing from any PC power supply *or* an FD-50x power supply. I also plan on having one that buffers all of the data, address & major signal lines on the board, so that experimenting might be easier without blowing the entire CoCo bus. Which leads to my questions: A) Anybody know anything about the company that marketed these, as I don't want to intentionally break any copyright laws; but with no info on the internet & the extreme possibility of the company no longer existing, does anyone think I'll be in trouble with the law WRT copyright laws? I'm mainly just using the original as a pattern for (1) the signal names & pinouts, and (2) the dimensions of the connectors & pins (I didn't have anything else that had the ground pegs on either side of the connector). B) I can prolly find this out for myself, but there are many others here better than me on the hardware side of things: What would be some of the better [a.k.a more useful] buffer chips I could use to buffer the address & data busses? C) Are there any *real* problems with powering the card from a separate power supply? I'm assuming I need to tie the grounds together, but I wouldn't want the +5 / +12 / -12 volt rails tied at all -- they should be separate, right? [[no, I really don't feel like dissecting my MPI just yet... altho I think it's the *only* piece of computer equipment I've never taken apart! ]] Should I check the voltage levels of the power supply & the CoCo to see how close they are, or as long as they're both within TTL levels is it OK? I'm mainly worried about the PC supply being of a higher voltage than the CoCo, if that'll cause problems. =-=-=-=- The designs (when they get closer to completion) I will have on my website for free, but if I make several cards and someone else is dumb^H^H^H^H bold enough to purchase one I would sell them for a small profit... Anywho, thanks for listening, and double-thanks for any advice that others might be willing to offer... ;-) Roger "Merch" Merchberger -- Roger "Merch" Merchberger --- sysadmin, Iceberg Computers Recycling is good, right??? Ok, so I'll recycle an old .sig. If at first you don't succeed, nuclear warhead disarmament should *not* be your first career choice.

HP & Compaq

by arthur.clark3＠verizon.net

I'll second that. There was a time when I thought HP was a great company making great products. Although they still make some excellent high-end computers, their home and office desktops and laptops are horrible. I have never dealt with a single HP computer that worked right. Their outstanding lead in the printer business is a thing of the past. There are now many companies making printers just as good, for a hell of a lot less money. Occasionally I see Circuit City or another retailer running a contest in which the prize is a HP computer. My remark is always "Second prize is _two_ HP computers." OTOH, all of the Compaq computers that I have dealt with have been trouble free. I think their maintenance HDD partition and peripheral BIOS/peripheral management is great. About the only thing that I don't like is their extremely proprietary design. That's fine on enterprise servers. It's inexcusable on a business desktop that someone actually has to support in a small business environment.
