Hi Gang: I have a Unibus bootstrap/terminator board with 4 ROMs on it. According to the field guide: M9301-YF U M9301 with boot for PC11, RP02-6, RS03-4, RK05-6, RX01, TU10, TU16, TU56, TS03, TTY, ASCII console, diagnostics There's a 10 position DIP switch on the board. Anyone know how to set the DIP switches to select the various bootstraps? What diagnostics are in the ROMs? This could be helpful. Thanks in advance, Kevin -- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca
