Apple II keyboard encoder - need specs for optional right-angle slide switch

[Ralph <rwhyre@gmail.com>]

I'm trying to track down details on adding a keyswitch to the Apple II
plus keyboard encoder.

I have a vague recollection of a specific "Apple Cart" article from an
1980 or 1981 issue of Creative Computing, it discusses the keyboard
encoder board on the Apple II plus, and mentions the specific C&K
switch part number that can be soldered onto the board to achieve
full character set generation (upper and lower case ASCII, and getting
ctrl-shift-P to generate the '@' sign) from the normally upper-case
ASCII only keyboard.  I did ask a few people in person over last
weekend, but they unsurprisingly couldn't come up with an exact part #
after 30 years.
(Atariarchives doesn't have these Creative Computings scanned in)

Thanks!

BTW, I found this gem of an article from M. Horton (previously at Bell
Labs), posted in 1983 - linking offsite
