HP 65 Card writer compatibility testing

[carolinahomes]

Earlier this week I was talking with someone who backed out of the idea, so the search continues and I thought I'd post this here:
Who here would like to mail user-programmed cards back and forth to one another to test the compatibility of their recently restored HP card writer functionality?
I've written 5 cards and sealed them separately along with what each card is supposed to do, you'll receive them, test them in your 65, let me know if they work, then mail them back in the self addressed stamped envelope. (My cards are in very pristine condition: no writing, dirt, smudges, oils and are not clipped.)
And then I'll do the same for your cards.
This way we can be more assured that our repair jobs are lined up within original spec.

I'd prefer to keep the shipping destinations within the continental USA.
