Retain DIP trough hole solution, please!

Before I finalize the new layout, does anyone have any preference for the size of the PCB? The original is 4" x 4", but I've reduced it to 3.75" x 3.75". I could make it a bit smaller than that, but would prefer to keep the PCB as a square.

I suspect the one from Adam is an earlier version than mine. It's labelled as "MP1" (which presumably means Minipulse 1), the ICs are all in sockets, and there are a few jumper mods on the backside of the PCB. The one I have is labelled "PTL 110" (probably meaning "Pulse Technology Ltd Version 1.10").

Pity I didn't see Adam's post earlier, as the back-engineering might have gone a bit faster.

Thanks for this NY present, Qiaozhi. Great work done. Did you measure power consumption?
