Well, you could make them!. For the monitor, convert a portable TV (I
wonder if those little 5" B&W TVs that seem to be available everwhere can
be turned into something useful. I can't believe they're that complicated
inside...). For the keyboard, either pull apart a PC keyboard and use the
swithc matrix, or make an interface between the PC keyboard (PS/2 type
port, I guess) and the rest of the system
You can find PC keyboards with 8048/9 or 8051 and put a reporgramed MPU
in. The reprogram can be done one of two ways, disable the internal rom
and piggy back a LS373 and 2716 or use the 87xx eprom part.
An those small B&W TVs are very modifyable, though at 5" 80char lines are
going to be tiny. There's at least one person out there that did it.
Or find a old HERC compatable (9pin) monochrome PC display even when
not working they are easy to fix.

Or do like
I did in the original portable unit - put on a 6845 and do your
own video display.
No way that would work, as I don't have a TTL level monitor here, or a
real keyboard...

I used a real keyboard once -- Pc's don't have real keyboards -- you
type with the mouse :D

I think a B&W VGA is what I want. Next years project ... 25x96 serial
terminal :)
Wait a moment -- VGA's are only 640 x 480 , I want 864 x 480 !

You've obviously never used an IBM Model 'M' keyboard then!
Yes, I have several, yes, they're ancient (in PC terms), yes, they're all
I'll use for as long as I can keep 'em running.

I switched over to model Ms exclusively around 1994 and all of my hand pain
went away. The tactile (and audible) feedback stopped me from pressing down
too hard on the keys; I was (subconsciously) never sure if my keystrokes were
registering or not with "mushy" keyboards.
At work, I use the model m variant with the trackpoint in the middle of the
keyboard (cable ends in both PS/2 keyboard and PS/2 mouse connectors) -- my
hands *never leave the keyboard* and I just love it!
The only reason I have an external pointing device at home is to play games.

I think it's not the "mushiness", but a question of key travel. I despise
notebook keyboards because of their short travel. I've got a couple of old
NCR keyboards (made in Germany by Cherry) that don't have the hard "click"
feel of the IBM, but have generous key travel nonetheless. If they could
do F11 and F12, I'd still be using them (oddly, there are 30 function keys,
but the 11-20 and 21-30 just generate shift- and ctrl- F1-10 respectively.
And F1-10 are where they belong--on the left side.
Cheers,
Chuck

Anything sub-portable. My fujitsu P2120's keyboard, whilst not as sucky as
I thought it would be for it's size, it's not perzactly a "joy" to type
on. ;-)
