Hi, the GODIL is thick probably too thick, but you can get one without the connector on the top installed it is easy to place 2 jumpers (small wires) under the board to connect GND and VCC (I only use the connectors on the top to connect a logic analyzer) btw: the 48 pin version is not really sold by trenz, I got mine directly from OHO, he sent me 2 samples (without the connectors installed) and a full set of connectors. my main problems with the GODIL was the power consumption, far above the original circuit, (I was playing with the 6532 and micro kim) -- didier On 04/09/2013 14:25, Istvan Hegedus wrote: > Hi, > I would say if the PCB is slightly larger than the original DIP that > is not a problem although e.g. in case of the plus 4 you could not use > that for TED replacement due to the space in the shield.
