Hmm, interesting. I'm fairly sure that the AdSpeed I have in my
Mega ST4 has round pins, not square...

I have two of them, one purchased new in box with all included items. One item included was a 64 pin CPU socket that is referenced in the manual and the AdSpeed slides in and out of that easily. Unfortunately the 2nd hand AdSpeed (probably more like 14th hand) didn't include a socket when I received it. Both of mine have very defined edge, four sided square pins. The body of the pins are definitely not rounded. Only the tips of the pins have a chamfer, and they fit VERY tight in machined pin headers. The 68000 on the AdSpeed sits in a machined pin socket and in this photograph you can clearly see the size difference and the shape of the pins compared to the machined pins.

Anyway, my bad for neanderthal-ing the thing out of my computer with a metal chip lifter against fragile components on the bottom of the PCB. Luckily, it was able to be repaired.
I wish someone would reverse engineer these because they're hands down the best 68000 accelerator.

Well, I'm glad you were able to repair it and I agree, they are awesome accelerators.
Someone like tOri might be able to reverse engineer it. I sent a Fast Technologies
T-25 accelerator board to him once and he was able to reverse engineer that one.

There was a guy over at Atari Age that was reverse engineering some of the ICD (AdSCSI I think was one of them) boards. Same person?

Everything seems to be working perfectly. Thanks everyone for the pointers.
Well done! Good result.

Yes, I think that would be tOri. Amazing work he's done/doing...
