Ok, this drawing wont look pretty (edit: it indeed looks pretty f####d up when submitted):
13 1
. . . . . . . . . . . . .__|SIMMSOCKET
. . . . . . . . . . . . . |BUSCONNECTOR
NC 25 14
Ok, I this is supposed to look like the 26-pin connector on the SCSI-kit - looking straight into it with the SIMMSOCKET and BUSCONNECTOR to the right. The numbers I have printed out are to which pin on the DSUB25 a pin on the SCSI-kit corresponds.
So the upper row from right corresponds to DSUB25-pin 1 to 13 and the lower row from right corresponds to DSUB25-pin 14 to 25. The leftmost pin on the lower row is Not Connected (NC).
If this doesnt make sense, just tell me
