Actually, I meant the RL02 terminator.  I have been entering bootstrap 
code by hand since one of my bootstrap ROMs went pins-up a couple of 
weeks ago - you may remember I posted asking about favoured boot ROM 
images?  Not to mention entering quite a lot of code into ODT by hand 
when I first got my 11/73 and *nothing* would play nicely...

Originally the Baydel multipurpose card could boot pretty much any 
common QBus mass storage.

Got the breakout board, in the BA23.  Haven't played with it yet though.
