What is that in the photo? A clip for a Lisa with two rows of inline pins? You took the crystal off the board (that's the component most likely to get in the way)

Bet ya that either A) you've got a short or B) you've got an unconnected pin.

The surface mount components on the left hand side are incredibly close to the Lisa chip reducing clearance and effectiveness of any clip.

If you've managed it... what next?

I could have gotten fancy and relocated the resistors to this board

Remove them from the PCB and solder 10's of wires from one side of the SMT placements to your PCB? Ooo not nice. Bound to introduce signal integrity problems. Not to mention analog stuff like impedance etc.

That's assuming that all those resistors are connected to pins on the Lisa.

Interesting... if this works and doesn't short what are you planning to do? Shave a real Indivision 1200's socket and moving the crystal away from that area perhaps out on wires?

I say... by the end of this decade that we send a man to the moon and do the other things, like fit an indivision 1200 into a CD32 with SX32 Pro.

We do these things... not because they are easy... but because they are hard

(And so are we)

;-)

Different shape and pinout though... most of the signals are the same. You can build an A1200->CD32 adapter PCB

So, in theory with this adaptor PCB you could put a Blizzard PPC and/or Mediator busboard in a CD32 too?

Not IN the CD32 but sticking out the back. Sure. I only tried a RAM card and a 1230 but I imagine anything would work.
