I need something like this, don't I?
Buy 12pcs 2.54mm pitch 15.2mm row pitch 2 row 32 round pins soldering dip ic chip socket adaptor at Harfington, get more Connectors & Adapters in various size.
Correct, but 32 pin would be for the rominator itself, you'll want a pair of 28 pin ones.
Hopefully this picture helps:
Rominator itself takes 2x 32 pin sockets, I personally would use the type in my picture, but I digress.
The mac Logic board most likely also has the pictured type ("Dual wipe socket"), but, if you plan on leaving the machine pin rominator alone you could use a 28 pin socket with the round pin holes (like the one you linked, just less pins). Alternately, you can literally cut 2 strips of headers the correct length, but I recommend a full socket ideally.
So in this photo there is an EEPROM which is used for the Hi/Lo on the rominator, pictured with the socket I would use. Note the leg width.
Then pictured are standard square pin headers, most breadboarders have piles of these, as well as a strip of proper female pins. Also, the round machined pins/sockets.
As you see the square and round pins are wider than the EEPROM pins. If the rominator were to be installed with machined round, or square, pins, it would widen the socket on the logic board. This could be problematic for reinstallation of factory roms.
In the upper right are the "right" pins, but I haven't soldered them by hand yet. I will learn soon enough...
Hopefully this helps clear it all up, sorry if I rambled or was redundant.
