- A co-worker has informed me that there was some discussion here a while ago
- about the OverDrive chip. As I understand it, an OverDrive is really a
- fully functional CPU which just shuts off the original CPU, but requires
- that the original be left in place.
-
- I'm particularly interested in a description of how an OverDrive chip knows
- that the original is in place. Is it just a matter of a couple pins shorted,
- or is there some complex handshake between the two chips?
-
- If anyone remembers the gist of that thread, I'd appreciate hearing about
- it.

- Q: I hear all this talk about base | rbharding@descartes.uwaterloo.ca
- memory, expanded memory, and +------------------------------------
- extended memory. What is the difference, and why don't I have them on
- my Amiga?
- A: Well, the Amiga doesn't offer you that kind of flexibility...
