Hi
Does anyone have a parallel out keyboard that they
would like to sell to me?

to those interested in a parallel keyboard, I have a few Kaypro II
keyboards from machines that were scrapped. I am pretty sure they are 8 bit
parallel. I am on the east coast though and won't be able to take a look at
them until I get back home on the 6th of February. They came off working
systems, so they should be just fine. I just don't know key cap condition,
etc. Email me if you would like one and I can email you in a few weeks when
I get home. Price is $10 plus shipping.
best regards, Steve Thatcher

Well, with only 4 leads in the coilcord to the computer itself,
they are definitely not parallel in/out!

Does this mean there might be a small market for a PS/2 to parallel
keyboard converter? I can envision two modes, output only, where ASCII
data and strobe are provided when a key is pressed, and an I/O mode, so
that keyboard commands can be clocked back in.
Multi-key sequences (like F1, etc) would be converted to VT100 keyboard
sequences. Perhaps a few others terminal types would be supported, such
as the TVI950.
Information like Shift would affect the keycode, but would not be passed
along (well, I guess we could, with a mode switch. But normally not.
It'd just look like the keyboard data stream from a serial terminal).

Tom,
Can you verify the pinout of the BigBoard? I'm a little suspicious
of the -12, and two pins are not defined, 21 & 24.

That was my first thought -- a PC keyboard + a microcontroller. Shouldn't
be too hard to write the firmware....
Of course, not being the business type, I would probably have GPLed it,
not tried to sell it ;-)

Here's one for connecting a PS/2 keyboard to an Apple II+ (ASCII
parallel) using an ATMEGA microcontroller:
<http://home.knuut.de/natti/keyboard.html>
For those of us that don't speak German, here's the discussion that lead
up to it:
<http://www.applefritter.com/cgi-bin/YaBB/YaBB.pl?board=apple2;
action=display;num=1070577979>
Vince Briel uses a similar design in his Replica I, also an ATMEGA design:
<http://www.applefritter.com/apple1/members/replica1/index.htm>
If you can't program your own chip, I'm sure Vince would be willing to
sell you one. I'm not sure how Vince's design handles lowercase, it
being intended for the Apple I, but he could certainly tell you.
