I have nearly had it with this machine.
The other day it was a LETA problem, and now it just won't boot the game at all.
I have no idea what the heck is wrong with it.
It boots into test mode just fine, says all tests have passed with flying colors. Vector generator tests look just swell.
But when it comes time to boot to game mode? Nah. Not about that. I'm treated to a blank screen, no deflection, and lazily flashing start lights.
Some initial troubleshooting tests:
- Swap CPUs - No Change
- Swap around Rams - No Change
- Test CPUs out of circuit - all good
- Test RAMs out of circuit - all good
- Test every single socketed chip I can out of circuit - all good.
Hooked up the cat box though, and then things are interesting. The gamma CPU section seems fine. But I can't get it to read the Alpha section. Maybe something intermittent? But I can't get it to read any of the ROMs or any of the RAMs properly. But if that were the case, how in the hell would it make it to the test mode with the actual CPU installed?
