[WP-34S] Cable and flashing options for Mac users

[John Galt]

The credit is all yours Jose, so far I've got nothing :-(

Everything is as you describe. After removing the back cover additional inspection reveals both JP5 and JP6 are intact, and continuity confirmed from both ends of them to J33 and J35, respectively. So much for that, but thank you Barry for your suggestion.

So I'm still stuck. I agree verifying the Rx to pad contact is essential, but I have tried physically holding the 1k resistor ends to the pads as well using as the spring pin connector I fabricated. It is not possible to verify continuity while the spring pin connector is attached to the back cover, but it looks and feels intact, and pressing it down with my fingers doesn't make any difference. I'll try it with the cover off but I already know that won't work.

Clearly I'm overlooking something obvious. I know from experience the hardware failure I suspect is rare, and the likely cause of this problem lies between my ears.
