Hi,
this is the "The Definicon 68020 Coprocessor", described in Byte 8+9,
1985 ...
... but it wasn't part of Circuit Cellar
Ciao Bernd

    You're probably thinking of the Trump Card, which
 used a Z8000.
 (Z8001 in particular)
         
    BYTE/CC did feature a 68020 based accelerator or some such for the
peecee. Now it only shared the bus, but sat on it nevertheless. What's the difference
I ask?
       
 
    Are you sure that was in a CC column?  I've read most everything he's
 published (in BYTE and otherwise) and I don't recall any 68K stuff at all.
