Got it: RD54 formatting write protect solved

Nice going! Related story: I had probs formatting a maxtor 11xx (not an actual xt-2190 but really close) as an rd54 due to geometry differences and binary patched that formatter to deal with it using the xxdp equivalent of od. Have the patched xxdp formatter binary on an rl02 pack here if anyone needs it. Works a treat, close enough that dec software thinks it?s an rd54.

On a BA23, the RD54 needs to be jumpered at the disk as UNIT 3, and I had it as unit 4. Thus the jumper needed to be between 3 and C, I had it one stake over between 4 and C. > > Fixed that, did the format where you do not select Autoformat, and downline load UIT and you get the disk going tick, tick, tick as the sectors are formatted.
