Yep, I remember as if it were...10 years ago...people bank switching Z80s up to
1-4Megs...and that's with a stock 16Bit address line Z80!

Looking at the ATA-2 spec...I might want to go with a 16bit bus CPU since IDE is a 16 bit
oriented bus (with an optional 8 bit bus mode) which probably would be the best since
newer drive may not support legacy 8 bit mode.  There is a nice Z380 that looks promising.
I considered using a simple 80386 but the design books seem to be out of print...not that
I wont head down to the used book store and see what I can dig up.

Yeah...I'm not complaining... ;-)
