Since my MicroPDP11/53 has no tape drive (and I don't have a floppy install set for MicroRSTS), I had the idea to install the complete OS into a SIMH pdp11 instance, and then use Warren Toomey's "vtserver" to transfer the resulting disk image directly to my PDP over serial console. Of course the trick here is to specify a SIMH pdp11 config that most closely resembles my hardware, as well as choosing the proper hardware drivers during the RSTS/E sysgen phase. Everything went flawlessly, and vtserver transferred my freshly installed MicroRSTS/E v8.0-6 RD31 disk image to my real RD31 drive. However, RSTS refuses to boot on the real hardware, claiming that it can't find a KW11-L line clock, a fatal error which drops to ODT. According to my KDJ11-D motherboard manual, there is in fact "CLK" clock circuitry at the very same memory-mapped i/o location as a KW11-L, so I'm puzzled as to the cause of this error. I figure there are only two possibilities: the 11/53's CLK isn't KW11-L compatible (which I doubt), or perhaps something was corrupted during the disk image transfer over serial, resulting in a misleading but fatal error message. I'd be curious to hear anyone's opinions before I reattempt, as transferring even a 20MB disk image over 38.4kbps serial is quite slow (write access to the RD31 itself is the bottleneck :)
