Is that right?!? What do you mean by "PDP11/73+"? You either have a dual-wide (KDJ11-A) mod- ule and some boot board (probably an MXV11-B) or a quad-wide (KDJ11-B) module. The KDJ11-B module should have all the boot code you need on it. The -A version uses ROMs on the MXV11-B module (the MXV11-BF ROM set). The -BF ROMs have lots more stuff than just the bootstrap - cache diagnostics, etc. If you just need a one-time boot, there are toggle-in boots kicking around. Most 3rd-party tape controllers (except TMSCP) include toggle-in boots in the manual.
