You are running POS (or P/OS) on a machine with a VGA display? (Sorry,
couldn't resist)...
I can't comment... I've nto seen your machine. But considering much of
the web does seem to be useless, I doubt it matters what displays it.
Surely a
graphical browser, (if NOT done in a High Level Language) could
be written to run on a 5150 with CGA.
I think most graphical web pages would be
pretty much useless at 320*200
in 4 pre-chosen colours... IIRC the origianl 5150 couldn't take a hard
disk.
Could be done, using a floppy boot disk with certain startup code.
Did any of them use the "extra" ROM socket on the 5150?
So with a maximum, of 640K or RAM
EMS
(LIM?) Although MOST expanded memory systems were 16 bit, and written
with 286 code, there WERE 8 bit EMS boards, and 808x software. I saw 8 bit hard drives running on PCs, and even on
Apple][, and TRS80
I wonder what an '8 bit ahrd drive' is. A cotnroller with an 8 bit data
bus on the host interface?
model 3!
I hve one on my Model 4 (same interface as the M3, of course). It's a 3rd
party one made by Cumana, who are better known for their floppy drive
units for the BBC micro. This hard disk unit contains an ST612 (IIRC), a
WD controler board, an SMPSU and a little bus interface (3 or 4 TTL
chips).
Of course there were also hard disks for the BBC micro. The Acorn one is
not too hard to find, the Torch one is very rare in my experience...
But this doesn't make displaying graphical web pages any easier, nor does
it solve the download time problem
