Happy New Year everybody from Scotland.
Congratulations on producing such a (so far anyway) detailed set of instructions.
I have just got to the "test everything works" stage after prepping the Poly800 main board - and it all seems to work! Whether by skill on my part, or by lucky chance?
Question: Does the mere fact that I can programme a sound and the controls seem to work, indicate that it is OK, or should I reload all memories and check all memory locations, sequencer, etc?
I have to say that removing the IC29 is quite a step to take (What was it Atom said? Non-trivial? I agree). You're kinda committed once you start this! I think we'll need a T-shirt after all this - the "I removed IC29 and didn't fry my board" T-shirt. It would have been easier if my desolderer wasn't old and worn - and the nearest electronics shop is about 150 miles away. Its also shown up a serious problem (don't worry - I don't blame you) - I can't focus quite so close to the board as I used to be able to!
I ended up doing the destructive removal, too.
I can't proceed to actually building the board and installing it tonight, as we need the kitchen table back...
Best Wishes

bah!! that's almost like reading through the instructions before starting!
btw, i first assembled the board, then prepped the 800. then, after
destructively removing the **138 from the 800 read about re-seating that
and the EPROM for testing... i did look through (a small part of) my chip
collection, but i didn't find a **138... oh-well... full steam ahead for
the smasher! doh! the **138 is socketed in the hawk board!
