We talked about this and put it in the category of "the hardware can do it so somebody probably will but we're not going to worry about it". > Other wishy things: > memory region visible to q/unibus as boot rom An earlier comment about how we wouldn't be able to boot off our native disk drives caused me to think along this direction too. This seems a nice feature and should be easy enough to implement. No hardware changes are needed. > ability to halt/reset the q/unibus (PDP-11) processor > (making the MCU into a "front end") Huh. Cute. We weren't planning to put in the ability to assert BHALT or BINIT. It could then halt the processor and examine memory but it couldn't see the processor registers or even set a start address. Or could it hack into the console terminal and send commands to ODT? Anyway, I'll leave that one to you. -Dave
