> I didn't fully disassamble the program I have now done so; the -YK is _exactly_ the same as the -YA (the later ones, which are minorly different from what's in the manual), except that the HSR address (177550) has been replaced as the primary device address by that of DL11 #1, in the second block of DL11 addresses (175610).
In other words, the ROM is prepared to load something in bootstrap loader format (which I have documented here: http://gunkies.org/wiki/PDP-11_Bootstrap_Loader the one program known in this format is the absolute loader) over the non-console serial line. Noel
