Just checked... i have 2 off 6800CPU.
One is a good "pull" and the other is new.
Ill put the new one the post...
... odd thing is, once i stocked up on 6800 and 6812 i havent had to use them!~
Im also pretty sure that one of my local elec stores has 6800 as NOS.. pretty sure thats where i bought them from
