Certainly not page--there's no native paging facility in the 286. That
came with the 386. However, the 286 can run segmented code and swap
segments in and out of memory. One could, I suppose, define a 64K page
size and fill the descriptor table with entries and so, in theory, have a
virtual memory size of half a gig. But you'd have to tread selector
arithmetic something awful.
AFAIK, no OS ever did this on the 286.

All,
I have the following up for grabs:
* ICL DRS 8801 manual (Users Guide and Ready Reference)
* Five or so 3Com EISA network cards
Available for pickup from Central London (Camden/Euston area), or I can
post if anyone wants to pay postage.
Contact me off-list.
Best wishes,

A: Because it destroys the flow of the conversation
Q: Why is top-posting bad?
I'm assisting in the construction and control of a robot for a competition
with my highschool based around a "fischertechnik interface". I don't have
any documentation or information on this interface, besides the fact that
it's parallel port controlled and most of the control was done through
various BASICS (C64, Apple 2, etc)
I'm not even sure the documentation I have with the basic listings is for
this interface.
I'm hunting for information, but there isn't much avalable for this.
The only real distinctive markings are "32372 - 1188 HD", FCC ID FZQ2WT
UNIVERSAL... it's a black bottom with a clear plastic topped case, there's
two sets of voltage inputs plus what appears to be a ground. there appears
to be two parallel port pin headers? plus the header for output and motor
control (four motor circuts)
If it helps, there's a blank IC spot with "4050" in it.

Hi,
I've been creating 'guides' on ebay for various terminals. I'd
apprecaite any feedback you might have. Please understand that the
manufacturer guides are "works in progress". Its pretty limiting to
have only 10 pictures per guide...

I'm trying to restore an Osborne Executive, but there seems to be
something wrong in the CRT circuitry. The machine powers up and beeps,
but I see nothing on the CRT. Fiddling with the CRT pots does nothing.
I hear none of the expected noises from the CRT circuitry, nor do I see or
smell anything burnt. Can someone here point me in the right direction?

Anyone have schematics of the power supply for a DecServer 200?
Have a dead one, and before I start poking around, I'd like some kind
of reference for it. Definately in the PS, fans not running, and
swapping in a good PS from another broken unit makes it work.
Dear folks,
Is anyone interested in an Amstrad PCW 8512 in good working order
(720k drive belt recently replaced, spare belt for 360k drive
available) with plenty of discs, Locoscript, Super Type and Desktop
publishing software, printer, spare printer cartridge? A second
PCW8512 also available with printer - but this needs new drive belts
fitted to its disc drives.
I am in the UK - Leeds (West Yorkshire).
Best wishes,
