Hey ericlewis - this is cool! Can I ask how you figured it out?!
Doing this for my PO-33 was on my bucket list.
I thought I might have to resort to voltage glitching to get a firmware dump, which is currently beyond my skills.
Unfortunately I think only a few of the PO's support this transfer method, and I don't think the 33 is one of them. They were never meant to be updated at all, as I understand it.
