- We could always use a undefined storage type. I know, it will mess up
- future software releases. (Yah right!) Actually it may not maybe we could
- just ask Apple which one. That way the lower 32 megs could (could be less)
- be a normal ProDOS and then you could create an extended directory file.
- This directory file could hold information like above. The key block for
- files in this directory could have a 4 byte pointer to the files key block
- which could be two 512 byte blocks with the high 2 bytes in the second key
- block. ProDOS actually has it in it to do stuff like this. It even has
- stuff to increase the length of a directory file so that more information
- to be added. I don't know. Haven't had a full night like David to think
- about it so this stuff is right off the top of my head.

- Yeah, let's get some comments about this.

- Now I understand about David's ideas. David is talking about extending
- ProDOS. I'm talking about writing a whole new DOS (FST), not just extending
- ProDOS. How about that? Any problems besides the amount of work?
