Hi gang,

I recently acquired a Lisa 2 and I'll need to replace the motherboard and probably the I/O board. I saw Will from Cay Mac doing a motherboard reload from Alexthecat123's recreated board. It looks fantastic & I'd like to try this, but my PCB is slightly different. I have a cluster of resistors near the J13 Parallel port (with a pair on the back side as well) that do not appear on Alex's board. I have seen other factory boards without the resistors as well.

Is the board w/o the resistors compatible with my Lisa?

What do the the 2 boards indicate? Is this a revision? I believe my card is Rev E.

See pix below:


Thank you,


Mark

PS: My Lisa 2 has no HDD and I am not sure if it ever had an internal.
