It sounds silly but I don't actually have access to a Windows machine,
but PD11GUI looks nice.
I managed to boot into XXDP today using tu58em and ran the RLV12
controller test. It seems though that the version of XXDP I loaded does
not support the 22bit address (17774400) and defaults to the
I have successfully built a rl02 disk using pdpgui on a windows XP laptop,
the newer version works on window 10. All you need other than the software
is a serial card like a m7800. Pdpgui acts as a gui. Do you have a m9312
