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...

The Alpha is still superior to the IA64. What other operating system
has the same clustering capabilities as OpenVMS (or better)?

Thanks, Pete. With this information I can get the proper cable.

Ah, one of my favorites, used magnetic core for the memory;
however, it would usually lose a byte or two on either
powering down or back on again...

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.

[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... ;-)

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.
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.
