Hi,
I'm thinking about building one of obtronix's apple 1 (ebay 8790381782), but he
doesn't supply a keyboard with these latest kits (like he used to). These are the
old-old ascii style. Connection to the keyboard is via a socketed 16 pin dip. The
signals are 7-bit parallel with a strobe signal. Gnd and +5v are supplied to the keyboard
from the Apple1. I'm told that Apple II and II+, early Franklin apple-clone systems
used a compatible keyboard. The Apple 1 manual: "Any ASCII encoded keyboard, with
positive data outputs, interfaces with the Apple system via a "DIP"
connector."
I've been looking around for a keyboard, without cannibalizing working systems (even
the Franklin).
Any of you have working keyboards on non-working Apple II/II+/Franklin-clone that you are
willing to part with?
Thank you!
Scott
P.S. (hmm, maybe I shouldn't have made the crack about the Franklin).

Dunno about that, but if you're looking for plain old ASCII, how about
these guys:

Certainly worth a call--I recognize the middle keyboard in the photo and it
is indeed ASCII. It's the Hall-effect one and is a very nice unit.

Nice keyboards ... get them while you can.
Also you can get new-old stock CP/M from them for $15.
The 8" drives to read the media are a tad more :)

They have a Pentium board for $619-$1189 depending on the Pentium chip (3
Year ALR warranty, is that company even around anymore?), that site must
have prices from 1997 still up!

They must be getting free web space to leave the site up that long! Too
bad.
Maybe a note to the folks at http://www.electronicsurplus.com might turn up
something--they always seem to have lots of odds and ends.
Failing everything, there's always using something like a PIC (programmed
in C, of course :) ) to translate a serial keybaord to parallel ASCII...

Got that site loading, but for some reason it's being slow.

Seems to me I remember one of Steve Ciarcia's articles in Byte had a rather
nifty little circuit to do that job, and it wasn't that complicated, just a
few gates and such -- I'm gonna have to dig that article out, if I still
have it. I remember thinking that it wouldn't be too much of a hassle to
plug an eprom into the output side of it to convert scan codes to ascii or
whatever else I might want...

XMission, my ISP, has a donated account setup for 501(c)3 non-profit
corporations. If you can document that you have a 501(c)3 non-profit
(or perhaps a similarly incorporated state non-profit) that is related
to your classic computing then contact me by email and I can help you
get setup.
Its basically the "business dial-up account":

They are my ISP. Pete Ashdown, the owner of the company, is a good friend
of mine and very much supports computing history and the demoscene,
among other things.
He also happens to be the Democratic candidate running for US Senate
against Orrin Hatch. If you're in Utah, vote for Ashdown! :-)

I had an empty Franklin mainboard and disk interface card one time some years
back, and this is part of the reason why I eventually let it go to some kid
that wanted to mess with it instead of building it up like I'd originally
intended.
I remember when I put the BBII together being told, on the subject of
interfacing an ASCII keyboard, that Apple-type keyboards (and clones of
them) would specifically _not_ work because they set the high bit. Dunno if
this hardware you're looking at expects that or if it's even a consideration
at all, but figured it would't hurt to mention it.

According to the Apple ][ manual, the keyboard outputs a _7_ bit code
(makes sense, ASCII is 7 bits, after all). These are read in as the low 7
bits of an input port. The 8th bit (MSH) is the latched version of the
keyboard strobe, and is set if a key has been pressed. The strobe is
cleared by referencing another I/O location.
Surely if you want to use such a keyboard with a machine that reads 8
data bits from the keyboard, all you have to do is tie the 8th input low.
