[game_preservation] PDP-5 Emulation

[Devin Monnens]

Marty,

Well, there's a slight possibility this might run on a PDP-8 emulator. This
overview says that the Type 34 works on the PDP-8:

http://www.faqs.org/faqs/dec-faq/pdp8-models/

This is the operator's manual for the Type 34 oscilliscope (should work on
both the 5 and 8). The game also uses the AS33 teletype, but this was
standard on the PDP-8 and PDP-5.

http://www.bitsavers.org/pdf/dec/pdp8/pdp8/DEC-08-I6AA-D_34D_Oscilloscope_Display_Control_Nov67.pdf

This catalog has the Type 34 instructions on pages 64 and 66.

I also know it's a 5" display with 1024x1024 resolution (addressable
points). Wow, that's small! (but high resolution!)

I'm not sure about the assembly set information. Are you looking for a set
of code?

As ICBM is the only program I know that runs on an oscilliscope that I
actually have code for, this will have to be the test software - so you
should document your expression when it gets running :P I wasn't sure which
file extension to use to save as a program, so it's in .rtf which should be
easy to convert. Bolded text is code I am unsure of.

Here is the original (yes, I just realized I entered the program's name
incorrectly).
