The trick is to include a logical 1750 and 1581, then have the drives memory as a DMA bank. The cpu banks are the same as DMA banks, but the REU chip is faster. Or system cost could be kept down by using just one cpu and no REU chip, but then the internal drive would not be useable in C64 mode . Henry J. Cobb hcobb@walt.cc.utexas.edu
