(!) That's a new one. I have no idea. I guess the answer is to coin it up
before playing...

And Tempest Rev. 2 works fine? That is, to say the least, very weird.
There's a grand-sum-total difference of two bytes between Tempest Rev. 3 and
Tempest Rev. 2... I'd go back and try Rev 2 some more-- see if your
flickering really does go away. If so, the only thing I can think of is
that the VROM expander EPROM is twitchy when set to the Rev. 3 bank. I can
send you a replacement to try if that's the case.
