Unlike other expansion ROMs ParaDOS has no checksum in address &FFFF. This fact should be considered when performing f. e. a ROM integrity check or similar. It the usual checksum algorithm is used the checksum is &26.
There is a special version of ParaDOS, it's called [[VaraDOS]] and has the Vortex format enabled by default. The Vortex format is the standard format for 80 track - doublesides drives, it was initially introduced by [[Vortex]] GmbH, then supported by all bigger producers of expansions and extensions for the CPC like [[Dobbertin]]. It's also supported in a variety of [[CP/M]] systems and [[FutureOS]].
