The following photos were archived from the now-defunct eBay listing 362354885325 “Vintage Honeywell Mechanical Keyboard K-83BC w/ Manual 5-pin White VG cond” from seller nickelsndiamonds1013 of store Nickels-n-Diamonds. This is a Honeywell RX Series rubber dome keyboard, catalogue listing 101RX43S-48E-J, serial number C0314, date 9049 (week 49 1990), model number 101RXd and FCC ID GJK101RX-5. The keyboard was assembled in Mexico.
The K-83BC Key Board User’s Guide depicted in the listing has nothing to do with this keyboard; it appears to be another manufacturer’s keyboard that had been adapted for use on the Apple II. The images showing various pages from that manual have been preserved separately.
