(Fixed) WP34s, unresponsive after trying to flash

[Peter Klein]

[EDIT]. I fixed ithe problem and was able to flash the calculator using a currently available cable (as of 10/2023). See this thread:

I was active here when the WP 34s was in development. A kind soul on the forum flashed mine for me. It is running version 3.1 3225.

Is it worth flashing it to the current version? My use is pretty casual. I never had the original programming cable. I do have a couple of USB FTDI serial cables They deliver either 5v or 3.3v to program and/or flash the firmware of an Icom V80 and a Radioddity GD77, both ham radio handheld transceivers. I don't know the exact voltage. The cable supplies Rx data, Tx data and ground. If I could rig up something with some alligator clip leads and pogo pins, it might be worth trying, but I don't want to brick the calculator. I'm running Windows 11 on my computer.

Thanks!
