The problem is what jumpers set it to 3? :-)

no I moved everybody up or stuck a grant inbetween.

Well, now that I have my KDA50 and if I can get the system to
work without RQXD then I can boot VMS 5.4. If that has a utility
to set up the KFQSA, I would actually consider booting it :-)
The only problem may be that the VMS system was configured for
a VAX6300, but I wouldn't be surprized if it worked, ... either
way I wouldn't.

That one had only two pins. Very fine pins for a huge box. I would
have considered securing the box with some extra pins ...

I guess so, if the part can be found. Ah well, I don't really need
lots of serial lines anyway and don't have room for the card in the
bus. So what the heck :-)
