RE: HP-97S IO
Use a slightly more capable micro controller and it ought to be possible to add SD card support in addition to the card reader. It would be slow entering programs and data but the storage would be huge.

It might even be possible to do the same thing on a 67 if the card reader is removed -- an Arduino Nano ought to fit, add a μSD breakout board and use one of the existing card reader slots for the card. I don't think the USB connector would fit in the other slot in the case but it could be enlarged.
