I'd love to! How long, how much?

Should I hold my breath, or just start putting pennies in the piggy
bank? I know that price/delivery is not your department Dave, but an
estimate +- $100, +- 1 month would be helpful.

Sounds nice, but will Commodore support this, or will it be hackers
only?  One question though, will the wait state from the MMU cancel the
speed gain from the 32 bit RAM?
