I kind of agree, I have need for sasi/MFM emulator instead, however....
Actually a new 'incompatable' IDE bridge would have a use, as copying from
A Winchester to IDE drive currently requires a 3rd file system in the middle.
That is IDE->1mhz bus->[econet/CPFS/RAMfs/anything]->1mhz bus->SASI->MFM
All because the IDE and original SASI versions of ADFS cannot co exist in
the same machine*.
* in the case of Mark's CF kit there is also the issue of bus termination
and chaining of devices (physical connections). Not all 1mhz bus devices
have pass through connections.
