I have 2x complete "1992" for parts, they were functional but have the key switches problems (mostly stuck pressed)
They have the original clock circuits (5mhz big osc can)
I had the project to modernize them to the tcxo boards made by Dan Watson but tossed them in a closet loll
I have 3x pcb's with 3x 10mhz ENE3311B oscillators
