Greetings,
I recently picked up an HP-67 at a garage sale. I had no idea what it might be worth but I was fairly certain it was worth what I paid for it. The calculator came with a soft case, quick ref card, AC power adaptor, & a stand alone battery charger. Unfortunately it did not come with any manuals or blank magnetic strips.
There is a strip with some key functions written on it that is directly above the keyboard. I'm guessing that this is a mag strip that has been inserted into the upper slot after it was at some point in the past passed through the lower slot.
See my absurdly high resolution photos at:

So with no blank cards and no instuctions I'm sort of at a loss as to how to tell if my unit is fully functional. Id like to do a test to see if my unit needs the "gummy" wheel repair but I need a card to do that and I can't figure out how to remove the card from the upper slot.
I have read that trying the card reader while on AC power is a bad idea so even if I had a card I'm not sure that I should proceed.
I'm guessing that my best course of action is,
A) Buy manual
B) Buy battery pack
C) Buy mag strips
D) Test
Any tips or suggestions would be welcome as would any offers to sell me a single blank magnetic strip. I see that I can get the manual off of this site and will probably do so and the batteries seem to come up now and then on e-bay. However, if anybody has an alternate source on the batteries they could point me to I'd appreciate it.
Any other tips/tricks/pointers would be welcome as well.
BTW, If my unit does need the gummy wheel repair, I may even try it myself given the excellent directions on this site.
thanks for any help or tips,
Blake
