Reverse Engineering the Macintosh LC III Logicboard

Looks like you'll have to file the 96-pin one and cut into a 21-pin to get the 18-pin extension… Maybe a hot-wire would work for that.

its very awesome to see the home made LCIII board is finally working/booting :)

it really has been awesome to see all the reverse engineering going on here, some proper hard work by some very skilled people!

I look forward to further progress and seeing what else gets done in the future :)
