(I especially find it cool that they list various part
numbers for the
connector. :) )
Digikey is the best source for inexpensive PET compatible connectors.
(1-800-DIGI-KEY) along with a ton of other cool parts.
I just noticed for the first time (!) that the "PARALLEL USER PORT" has
pins labeled "T.V. Video", "T.V. Vertical", and "T.V.
Horizontal"! Has
anyone actually connectd a TV or external monitor to a PET?
There are plans for a composite video converter using those pins in Nick
Hampshire's PET Revealed, I think it only works on the older 9" screen pets
and not the 12" ones. The reason for it being on the user port was for deaier
diagnostic testing.
I'll scan the circuit and put it on-line tonite:

The only Commodore computer with rubber keys that I have heard of is the
Commodore 116.
I'm trying to find out what PET has a chiclet
keyboard. I only know of the
plastic bang-on-em keyboard PETs, not one with the rubber keys.
There aren't any with rubber keys as far as I'm aware.
"chiclet keyboard" != "rubber keys", IMHO. I'm talking about the
cute
multicoloured keyboard with the small plastic keys that are arranged in a
grid pattern. I call that a chiclet keyboard.
The original PET 2001 (4k or 8k), and I saw a 'Teacher's PET' with such a
keyboard too (proably had a newer motherboard though. In general they
(calculator keyboard model PETs) were sold till about 1980 and are the
origninal keyboard design.

Hmm, okay. But multicoloured? Which colours? Arranged how?
Ummm they were all metallic tops, Red, Gold, Blue, Silver... Check out my
PET page:

You can see the colors pretty well on the first image.
If you want exact placement I'll scan a keyboard layout from the PET user
guide tonite:

Gosh, Larry, don't you want to live dangerously? Switching EXROM and GAME
in realtime? Live a little! ;-)
After a few Commodore (PET, 64, 128D and Amiga 1000) mishaps between me, my
brother and a couple friends, I have become much more careful. I do not want
to be the holder of the 'golden butterknife' (yeah, that one went over your
head, it's a long story.)
