there is no hope to use liber809 on a standard cpu socket...

r/w is pin 34 on standard 6502   and pin 36 on sally

pin 35 nc on standard 6502  and halt on pin 35 sally


it might be possible to use liber809 on a standard 6502

with a little adapter to put r/w  pin 34  --> pin 36

and pin 35 with a pullup to make sure halt is not activated on pin 35
