[HECnet] KLH10 on Raspberri Pi / Nodelist update

Hi Jordi, I've not messed around with TOPS-10/20 and only VMS on simh, but there you need specify which O/S is running inside the VM and specify it with something like: set cpu idle=VMS If I get it wrong or omit it, then it will sit there wasting a huge amount of cycles on my alpha. Off the top of my head, I suspect simh is actually looking for instruction patterns for the idle loop and detecting based upon that, which would differ from O/S to O/S. Perhaps TOPS-10/20 requires something similar?

Issues to solve - KLH10 does not idle in the Pi. I'll check the idler device code to see if I can guess what is happening. - I tried to give KLH10 its own bridge device, plugged into the rest of my network via VDE switches and plugs, but it does not work. I have lots of IPBLP bugchecks and IP networking is unusable (weird enough, DECNET and LAT seem to work). It works fine if I use the main host interface in non-exclusive mode (but then I don't get LAT). - KLH10 frontend can't load *.EXE files. - TOPS-10 does not run well. I used a x86 KLH to dump the load code in SAV format and then I can boot TOPS-10, but it hungs after a while. On the other hand, I'm thinking about building a blinkenlights device using the GPIO pins of the Rasp-pi basing it on the actual parallel port blinkenlights panel driven by the "lites" device... :) It could be another nice hobby project...
