HP30b flashed with WP31 no longer responding

Thanks for that reference Walter. Fortunately I picked up the manual before embarking on these builds, so I'll work through the troubleshooting section. I hope that works!

Marcus, my JTAG experience to date has mainly been with Xilinx devices. However I do have an STM32 JTAG, and that appears to be supported by the Olimex ODS toolchain. That's far deeper down the rabbit hole than I planned to go with this project, but "In for a penny, in for a pound" as they say. I've seen references to soldering on the necessary connector, so hopefully I can at least answer the "Is it still alive" question.

If all else fails, there's still Option Eric!

Thanks for the advice,
