ISTR that's correct, and that's unsupported as in "We never could get it to work right, so you're on your own..." The suggested solution I've seen is to replace it with a DELQA board. :) Try it with 6.2. If it works, it works. If not, let me know, I may eventually be able to get a bootable MicroVMS 4.x setup on tk50. That is to say, I have MicroVMS 4.x on a VAX with a questionable RD54 (takes several minutes to spin up properly), and a shot tape controller. I will, as soon as I can replace the tape controller, produce a bootable backup if it kills me. Ok, have you tried booting it conversationally, and turning off the clustering? (I have never tried this, but it seems like it might work.)
