Wrong.
I have forgotten the address to poke (or is it peek - some such action)
which
causes the AppleII (original, +, and E) to enter the system monitor
software.
Therein it is easily possible to manipulate all manner of system features
and
memory contents. If you need the exact information thus, I shall extract it
from
the manuals, etc that remain in my possession. I own a II+ and a II E,
since it
is only upon such machines that I may execute the Apple Worm (as published
in the May 1985 issue of Scientific American, Computer Recreations column)
which I wrote so many years ago.

I know perfectly well the accepted definition of personal computer but,
language is as much subjective as objective. So, though society may
subscribe to a specific definition, there is no reason to assume that
all persons of that society also agree to subscribe. After all, this is not
France, and we have no national language police. Nevertheless, your
point is well taken.

I'd like to put forward a documented record of hauling a PDP 11/45 and
TU-10 tape drive and separate racks up two flights of stairs into a third
floor apartment between three people.
I'm sure someone will challenge this record and put it to shame, but I was
impressed with the feat.

I have two O'scope crts (3BP1 and a 2AP1) that are still good (they were
purchased as military surplus when I was a teen for homebrew use) and
neither were made much later than 1958 (maybe much older!). I know they
work as the scopes I built with them still operate! The glass
doesn't decay. If the phosphor is peeling it may be that someone has
vented the tube to remove the implosion hazard.

I suspect that you have several. Hence, what is currently in your
repository?
One interesting piece I have is a MicroWay 80860 board. It is
generally described as a single chip Cray 1, and can in bursts
(perhaps at greater rates) compute at 80MFLOPS on a 40MHz
clock. As it happens, this processor is not quite fast enough but,
with about 10 times the power, one could watch movies of flights
about the Mandelbrot set in real time at about 1600 by 1280 pixels
in 24 bit color.

i'll check the next time I'm there (in a few days...) I'll let you know...

Do they have any old laptop parts? Such as a HardDrive controller for a
1400HD?
I know the 1400 isn't quite on-topic (1989), but I use it to keep all the
records for my other (over 10-yrs old) computers on. Now the HD controller
went, and I can't open anything (can't even boot the computer). Does that
make it on topic?
ThAnX,
