* 8K ROM data has 4 regions. There is an NMI vector at offsets &0066, &0866, &1066 and &1866 which indicates within the ROM data. This suggests each of the 4 regions is selectable and mappable into the range &0000-&7ff. What is not clear is if the regions repeat or not in memory space.

* Region 0 appears to be save using a filename of "DraySoftONE". * Region 1 appears to be load. It has What is not clear is that when the text "EVESHAM MICROS PRESENT DISC WIZARD (v1.2) Loading". * Region 2 appears chosen region is mapped into the Z80 memory space if the region in &0000-&7ff is repeated through to be saving for "DraysoftTWO". * Last appears to be loading for twothe end of &3fff.

The - Region 0 appears to be for saving "DraySoftONE". - Region 1/appears to be for loading "DraySoftONE"- Region 2 Switch chooses between which 4k, then the load/save chooses between the 2k within that 4kappears to be saving for "DraysoftTWO".- Region 3 appears to be for loading "DraysoftTWO"

It seems that the "1/2" switch on the PCB chooses between which 4k (assumption it is connected to A12 of the EPROM), then the "load/save" switch chooses between the 2k within that 4k (assumption it is connected to A11 of the EPROM). * Uses Dissassembly of the code indicates it uses direct FDC disc access for loading/saving. * Uses Dissassembly of the code indicates it uses an I/O port &f0e0, and sends the data 0,1,2 or 3. It is not clear the function or the exact decoding of this port.
