If you are correct about the version being 6.01J then you need the DOS PCP (SBU 6.10) to program the system. I'm kind of curious why you don't go through a vendor though, since the system is at least partially designed, and then manufactured in Israel, I'd think there would be a few dealers around. If you've never programmed a Telrad and need to set it up from scratch, that could be very daunting. If you're just making a few changes then I'm sure this group can help you.
