Macintosh LC 475 ..... need a little help

[jajan547]

Done already... The original is an 8 layer board, I imagine it's no fun at all routing the whole address and data busses through that narrow area on the board between host socket and CPU.

Got one of those too. You can swap the crystal for one with 100MHz and it will happily run the CPU at 50MHz.

Done already? Do you offer these for sale?

Done already?

Regarding cracking the PLDs, yes.
Partially done with noodling out the schematics and looking into how to route this thing so I won't need an 8 layer board.
