Can it run Doom?

[Lars Brinkhoff]

I see no PDP-10 here.

Will it even fit in a 256K address space?  If someone manages to compile it with ITS' ... er, exotic C compiler, I promise to add the "Color TV" display to the emulator.

This looks like a promising start:

If it can run on a Flipper Zero, I see no reason why it cannot run on a PDP-10!

256K is a tight squeeze, esp since that would likely have to include an OS and the video framebuffer...

(I suspect the Flipper Zero has its OS/firmware in non-volitale storage outside the 256K RAM.)

that's a fun website canitrundoom -  do like the idea of my toaster doing something more useful than just boring toast!

The OS is not in the same address space as the application.  The application could even be split in several 256K jobs if necessary.

But is memory the problem here? We know that even a Raspi Pico RP2040 microcontroller can run Doom, but it has a clock speed of 133 Mhz ! I think speed would be the bigger problem. Even ehen offloading some stuff to attached PDP-11s.

I've seen Doom run on (the display) of a digital pregnancy test. 

Seems like there might be a way to run it here.

Well, yes and no - they swapped out the CPU and display to run Doom on a pregnancy test stick...
