... and on the 999th time: success!

It was Jonathan who put the bug in my ear. The $1.79 cables I bought had their "green" and "white" functions reversed from its $1.79 eBay description. I can't blame Prolific since they don't make cables.

Although I followed Jose's schematic, the cable I used is evidently opposite from his (and Jonathan's). My "white" has to go to J35 and "green" to J33. Out of curiosity I swapped Tx and Rx earlier in testing, but other factors probably prevented its success then.

Compare the picture of my cable below with dewster's picture from his site. Mine lacks the TxD and RxD printed markings of that one, but the positions are almost certainly identical.

The loopback test worked for obvious reasons.

Now comes the hard part... duplicating everything I did and documenting it.

Thank you everyone! I hereby appoint myself the resident Mac WP-34s flashing expert, but it's everyone else who deserves the credit.
