 To access the pins on the 8279, some sort of socket for the 8279 and plug to contact the existing socket will be needed. ​ This might be a daughter card or a 40 pin socket with long pins that wires can be soldered directly to.  These are relatively slow TTL level signals, not the Z8 high-frequency bus signals. To access the pins on the 8279, some sort of socket for the 8279 and plug to contact the existing socket will be needed. ​ This might be a daughter card or a 40 pin socket with long pins that wires can be soldered directly to.  These are relatively slow TTL level signals, not the Z8 high-frequency bus signals.
