Anyone running BOTH PiDP10 and PiDP11 (and/or PiDP8) simulations on the same RPi?

[sunnyboy010101]

Background: I have hardware versions of all three PiDP systems: PiDP8, PiDP11 and PiDP10. The 8 & 11 are currently offline, but were running on much older Raspberry Pi hardware - essentially what you could buy when the PiDP kits came out. So most likely the 8 and 11 were on RPi 3's, though the 11 might be on a 4.

The PiDP10 is running on a decent memory Raspberry Pi 5, and it running great. Prior to the kit arriving I configured a second R-Pi5 with the PiDP software so I could test things (like which M.2 SSD hat would work best; cooling, etc.) 

I now have what is basically a spare R-Pi5 with PiDP10 software installed but not actively running.

What I'd like to do is get at a minimum PiDP11 running again on this newer, faster hardware as I really want to play with BSD 2.11 again.

SO - Has anyone else tried installing multiple PiDPs on one Raspberry Pi? Any catches or other "gotchas"? How did it go?

Thanks in advance,

Well, there's nothing preventing running multiple simulations with simh simultaneously if you know your way around it. You'll need to make sure your network configurations aren't incompatible (port assignments included), is the main thing that springs to mind. You'll definitely want to make sure you don't try to drive two incompatible panels (which, if you run the supplied kits as-is, both are going to try to do through the GPIO).

But yeah. Minus those things, it's all simh and there's no conflict afaik.

I should have been a bit clearer. I followed Oscar's instructions to download and install the PiDP10 system on the RPi-5 and it's been running perfectly. No hardware kit here, just a headless Pi5 on the network. (the kit version is on a shelf with it's own RPi5).

I'm wondering about following the directions to install PiDP11 on the same RPi as the already-installed PiDP10 system. My concern is that each version of PiDP (8, 11, 10) assume a Raspberry Pi with a fresh debian (raspian) install. So I'm more worried about interactions between one version of the PiDP conflicting with an already-installed instance of a different PiDP.

I do not plan to operate both PiDP "systems" at the same time. It's either PiDP10, or in my case PiDP11 (BSD 2.11), but never both active at the same time.

Again, I'm mostly worried that following the PiDP install instructions for say PiDP11 on a system with PiDP10 currently installed will "break something" because they weren't designed as co-resident.

Ah, I took your question to mean you were going to run both systems at the same time.  So I would have also cautioned about them both trying to use GPIO.  Myself I would have just installed Debian myself and then Simh.  Then create your own areas for both system and make a script to run one of the other.  Or manually run whichever.  I'd not want the overhead of the panel stuff running if it will never see a panel.  It won't cause issues.  But it kind of a waste of cycles.  But who cares?  :)  I would think you would possible overwrite one install with the 2nd.

I think it would be fun - if it's at all possible - to have both an 11 and a 10 running on the same RPi-5, where the 10 is running as a KL, and the 11 is running RSX-20F from a shared emulated RP06 - and provided the support for the terminal connections.  (However, it would require someone to write emulators for both sides of the DTE-20 interface, which (even in the real systems) was a royal pain...

Thanks and regards,
