I have two 65C102 co-processors. One of them lives in my Master Turbo, Econet Station 200 where it has always lived since I bought the machine in about December 2002.

The other I bought in 2005 and it lived for a while in Econet Station 1 before I transferred it to Domesday duty in the autumn of 2006 in readiness for my 20th anniversary Domesday Machine.

Prior to that I had used the old external 6502 cheese wedge which works perfectly well but doesn't look quite as neat as using the internal co-processor.
