Got a Tempest that my fluke is not able to get the correct sig off 123, and 124 roms. Nor do a ram check. I've checked all the buffers, and I'm getting address lines toggling like I should.

Basically what I get is a long low beep when I go into test mode.

It's a version 2, but I think it may have had 2532 roms at one time. Although I'm not seeing any hacks on the board, but then I'm not sure where I should be looking either.

Just tossing this out there in hopes that some ideas will be generated while I continue the hunt for the address/decode problem.
