No, it'll take a NXM trap (through 4); what happens then depends on what the trap handler is set to - if anything. > However, a P entered in ODT will attempt to continue the bootstrap. See above.

You could set the PS to 340 and the PC to the start of the bootstrap, and do a 'P' to start it running. (Using 'G' to start the bootstrap will clear the PS.) But I guess you've still got the NXM trap to contend with. If the bootstrap doesn't set the trap handler up, you could manually key in the vector (at 4) and a real simple trap handler (e.g. just dismiss, with an RTI), and you also might have to set up the SP.
