Sources for 8b TTL keyboards (Keytronics)

[Michael Lee]

So in the end, is there any source of old ASCII, 8b, TTL keyboards?  
Been monitoring the thread, but there doesn't seem to be any source 
available for them anymore or anything I might be able to salvage one 
from that isn't a desirable vintage item. 

I ask because I would like some for the Obtronix Apple I kits, and don't 
want to have to take apart my working Apple ][ and/or ][plus units for that.
