The HP 34E Ir with PANAMATIK ACT

[Geoff Quickfall]

Your up,late!

Catching up to speed on FRAM flashing.

Could be 3.3v cable but nominal range is 3 to 5v if I am not mistaken. You say it flashes outside but not when plugged into the 25 PCA. could there be a draw in the chip to the PCA that is interfering?

Cheers,

Flux is your friend and protocols are important.

P.s. Thanks for your work on the FRAM project, extremely helpful including the toolkit!
