Help RA / Wirings

[Panwork]

Hello here,

I wish could success to emulate old Panasonic 5.25 DD (JU4752AEG). Other people have success in this operation witha LOTHAREK.
So I try to do things same. But can't have probant results. When I try to execute code, the GOTEK displays A "RA" message and 0 or 1 octets delivered but not more...

Is it related to the P2000 or something else ?
