Hmm - don't know, if you call that accurate, but I have at least the timing
info to be programmed into the cards:

htiming[HTIMINGS] =     /* horizontal timing in ns, descending hfreq */         
{/* width  bstart sstart send   bend   total  dummy */                          
 {  44288, 44288, 45400, 53700, 53700, 53700,     0 }   /* 18.432 kHz */        
};                                                                              
vtiming[VTIMINGS] =             /* vertical timing in lines */                  
{ /* width bstart sstart send bend total polarity & htiming */                  
 {   348,  348,  352,  370,  370,  370,  HPOS | VNEG | 0 },     /* 50 Hz */     
 {   350,  350,  364,  370,  370,  370,  HPOS | VNEG | 0 }      /* 50 Hz */     
};                                                                              

If you don't find the pinout somewhere on the web, I can have a look in the
attic and see if I can dig out the manual for an old PC-XT I once had.
I _think_ it had the pinouts.

CU, ANdy
