Here's a question... I get a lot of laptops minus their PS's. The ones
that are 12vdc or 9vdc with a standard plug are no problem, but the ones
like the outbound (I'm lucky enough to have a PS) or the GRiD's (17.5vdc?)
or whatnot aren't even covered by the select-a-warts from Radio Shack.
So, does anyone make a box where you can set it for whatever voltage you
want from, say, 1vdc to 50vdc or something, with some way of hooking up
different plugs? Does anyone know where to get such a beast *cheaply*?
Thanks...

Nah, these were frenchmen, (independents) known throughout the state as the
best in Citroens. That's all they did. They had no problem working on the
citroens and keeping them running.
I, on the other hand, couldn't understand the inner or outer workings of
those vehicles. I still think that whoever designed 'em must have been
jealous of swiss watchmakers, but with all the design skills of the
samsonite gorilla.

Yeah, but you have to remove the (rear) fender to get the wheel off, (I'm
not kidding!) and who wants to do that when you've got (what I at the time
considered) a major celebrity in the car? I limped along back to Moscone
and dropped everyone off before skulking off to a nearby parking lot...
P.S., I still have scars on my right hand from another time working on
those #$&*@( things... Give me a Land Rover any day! 8^)

Hi,
If any of ya'll out there are interested in a Kaypro 4
"suitcase" computer, I have one on the ol' "trading block".
The machine itself is complete and working but I do not
have any diskettes for it. On power up it displays a
"please insert system diskette in drive" type of message.
Per my previous postings I'm mainly interested in
calculator stuff (and have a detailed "want" list on my
Web site). Please write me directly if you have any
interest in this machine.
Regards,
Alex

You could use a camcorder or camcorder charger to charge the battery. It
would be a lot safer. You could overload the supply if it's not the right
volt/amperage, worse yet, you could blow something in the computer.

Yes, that's it. My copy was published in 1971, so the HP9100A is one of the
later computers in it. Yes it is neat with the custom CRT and all the boards
stuffed into its case. I guess it sold for about $6000.

My guess would be a DG NOVA/Microflame series. It's the only one I know

Look around they are fairly common. DEC Published them every year from
late '70s through the 80s. Also check with your local DEC down under
as they may have a copy in the office.
On the other hand the ones you have are scarce!

The directory's there, but the pages are called "index.htm" not
"index.html"... looks like they were created with that nasty FrontPage
stuff.

I found a book I would recommend if anyone finds a copy, although I am still
getting used to it. It is "Computer Structures: Readings and Examples" by
Bell and Newell. It uses strange notation (for me) and even the table of
contents is "virtual".
Anyway, it includes descriptions of 2 desktop calculators, both about 1968:
an Olivetti 101 (USD$3500) and a HP 9100A. The HP uses core memory, its
program ROM uses 16 layer PC board technology. The HP article is a reprint
>from the HP Journal. Does anyone have either of these?
There are many other computers described, both common and uncommon. Some are
valved, such as the UK Pegasus, which was only 3 "bays" large.
