Hi Mike

Happy New Year everybody from Scotland.

Congratulations on producing such a (so far anyway) detailed set ofinstructions.

I have just got to the "test everything works" stage after prepping thePoly800 main board - and it all seems to work!  Whether by skill on mypart, or by lucky chance?

Question: Does the mere fact that I can programme a sound and thecontrols seem to work, indicate that it is OK, or should I reload allmemories and check all memory locations, sequencer, etc?

 I have to say that removing the IC29 is quite a step to take (What wasit Atom said? Non-trivial? I agree).  You're kinda committed once youstart this!  I think we'll need a T-shirt after all this - the "Iremoved IC29 and didn't fry my board" T-shirt.  It would have beeneasier if  my desolderer wasn't old and worn - and the nearestelectronics shop is about 150 miles away.  Its also shown up a seriousproblem (don't worry - I don't blame you) - I can't focus quite soclose 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 ittonight, as we need the kitchen table back...

Best Wishes

bah!! that's almost like reading through the instructions beforestarting!

btw, i first assembled the board, then prepped the 800. then, after
destructively removing the ∗∗138 from the 800 read about re-seatingthat
and the EPROM for testing... i did look through (a small part of) mychip
collection, but i didn't find a ∗∗138... oh-well... full steam aheadfor
the smasher! doh! the ∗∗138 is socketed in the hawk board!
