- I think you should try to get some more information :)
-
- Z2 is a bus with 16bit data and 24bit addresses (actually 23 because
- the least significant bit is decoded into two data strobes).
- Z3 is a bus with 32bit data and 32bit addresses.
-
- On all A4000s you can use Z3, all 32 data bits and all
- 32 address bits.
-
- The problem with Buster was that DMA boards weren't working.
- You could only use passive slave boards (like graphics cards
- or memory cards).
