- The A2386 uses page zips. With 3 Mbytes installed the 256 kbytes x 4
- should be in banks 0 and 1 while the 1 Mbyte x 4s would be in bank 2. If
- they are all page zips then there has to be something else going on to cause
- the problem.
- I have 8 Mbytes of 70ns page zips on my A2386 and haven't had any
- problems with it. I have page mode enabled (of course) and I think wait
- states are also enabled (I'm not sure and I'm not going to interrupt it, yet).
