Pim, a better suggestion than my previous one is to look at the info and
codes for vbl.clock, clock code for ProDOS and a //c that uses the VBL
signal from the mouseport.  vbl.clock (binscii encoded) may be found on
apple2 ftp sites, including:

ground.ecn.uiowa.edu  apple2/apple8/Utils/vbl.clock

  and  VBL.SHK.  VBL.SHK is also in the apple8/Pgms/Basic/ folder, but may
be a different version.  Check both.

If someone else doesn't offer, attach your pgm to any e-mail and I'll test
it on my //c  (the 2nd version that supports Unidisk3.5, but not the
memory expansion card).  Please tell me what to check for and what code to
twiddle with for simple tests and trial patching.
