I wrote that manual on Aminet (see docs/help/PC-Task_Guide.lha) and I wrote a FAQ.
PC Task and PCx work ideally with MS DOS or DR DOS (which is downloadable), although you need a 1.44MB floppy drive, although 720K drive will work it requires more fiddling to install DOS.
A 98 floppy will also work but has less MS DOS commands and files than previous dos'.
