Hello, I have a few quick questions about what could be added to SIMH. Not that I could add the features, my skills at C are not quite excellent, so in general, I wouldn't really be able to add anything to the project... or it would be better to say, I wouldn't be able to add anything remotely competently.
Any way on to the questions! How difficult, and better to ask, how possible would it be to add the following to SIMH at some point in the future? 1. Some way of interacting with devices while the simulator is still running. What I mean would be some way of breaking to the "sim>" prompt without halting the simulated CPU. So one could do things like swap disk packs, floppy diskettes and magnetic tapes without halting the system. Kind of like the way the Hercules emulator let's you affect the system on the fly. 2. Additional MASSBUS controllers and disks. What I mean is, since the actual PDP-11/70 could have four RH70 MASSBUS controllers installed in it, would it be possible to have another set of RP disks and TU tape drives added to SIMH? Also, would it be possible to have the RS03 and RS04 fixed head disks added to the RP device list? I ask only of the RS03 and RS04 because while they are not strictly necessary any more (being they were small logically, but rather quick, swap disks), it would be nice to have to be able to (re)create more "authentic" systems. 3. Would it be at all possible for SIMH to become capable of supporting a multiprocessor system? E.g. the PDP-15's UNICHANNEL-15 option, or the PDP-11/74. Thank you to any who answer this e-mail. I'd try my own hand at making some of the modifications to the SIMH codebase, but as I said, my skills at present are far too low to be of any real use.
