They're .1uf since they are designated like the other .1uf caps in the assembly diagram. But they are not shown in the schematic AFAICT.

.1uf 50v 20% axial ceramic should be fine (104M designation).

There was a note somewhere that indicated what they are on the the assembly diagram but I don't remember where I saw it. But don't hope to ever find them in the schematics - they're not in any version all the way back to Laser War.

Originally those were glass ceramic - very stable, more expensive, almost never fails.

Out of curiosity, how do you know they are blown?

C84, C85, C86 DE CPU Board

That's weird - they're on the blanking lines - something else is not right there...

Maybe it was the sound board I saw that on and it was never on the CPU schematics/parts diagram at all. So if you were only looking at the CPU schematics its understandable how you could miss it.

Keep us posted on what you find.
