For me, a personal computer is defined as any computer that I own and
operate. If I could find a SYS/360 or SYS370, or Sigma/7 or Sigma/9 or
a CDC 7600/6600/etc or a DPS/9, or ... ( well, you get the idea), I would
consider such a computer a personal computer. Any body know where
I can get one of these behemoths?

Hello, all:
Here's what was posted tonight (there's not much more that I have
scanned, so tomorrow should be it :-))
- R650x Family Datasheet/Rockwell
- 6581 SID datasheet
- 6567 VIC-II
- 6522 VIA
Enjoy.

interesting card! certainly has a lot of components on it. have you a chance
to test it yet. you could try to put it in slot 5 for instance and then do a
PR#5 or IN#5 to see if anything happens.

Oh dear, Alan. I assure you there was no intention of causing offence.
I took Sam's "Exactly" as referring to the last sentence of my paragraph.
My description was "exactly" what he was doing.
I had envisaged Sam as having a power supply with a plug on the end, and
wanting to know how to wire up a socket in the machine. Later posts
suggest that your test would have told Sam what he needed to know, so if it
makes any difference, I apologise for my hasty criticism of your
suggestion.
But please bear in mind (you're new to the list aren't you?) that on
Classiccmp, we all treat the other subscribers as old friends, and seldom
stand on ceremony. Remarks like those above are not intended personally.

That's exactly why. The iMac tries to say "Computers are no longer strange
boxes with blinkenlights that are scary and ugly. They are friendly, cute,
pyrex-and-kenmore appliances for the average home. They look good, and
don't have to be hidden under the desk with lots of wires running
everywhere." All it needs is a bud vase and you've got the computer
version of the new beetle. A kinder, gentler computer.
Sony tried to do it with their name -- people are quite happy with a Sony
stereo, so why not a Sony computer? But Stereos are still to complicated
for many people; they just don't think that way. Going back a little
further, someone pointed out that the Lisa was very similar to -- if not
modelled after -- the old IBM tubes, keeping that geek-ish-ness going,
despite the GUI.
The iMac "offers a blue box in a black and beige world."

Using a slightly different - and, indeed, almost invisible -
marketing strategy, millions of copies of Microsoft BASIC
were sold - one inside each and every Apple ][+, ][e, and //c,
for example.

MBASIC was also commonly bundled with many of the popular
CP/M boxes of the late 70's/early 80's. This is probably
a couple million more copies.

Anyone have any more info for this guy?

Most are their for two reasons on DEC hardware. One, so you don't pull
a card with power applied, instant fried system. The other is many of the
systems are air cooled and the cooling is not effective if the door is
open, running for extended period at elevated temperatures is a path
to lower reliability or worse.
In the alpha server that chip pumps out a lot of BTUs and cooling is
good karma.
