Hi, this is maybe a shot in the dark, but try to take out the SIMMs, and just run with the basic memory config (4Mb?). If this works, and then you insert the SIMMS and get the problems again, I would suspect SIMMS with too slow access time. I think the "dirty ROM" issue you mention has to do with 32-bit clean ROMS, starting from ci towards the new machines. It only means that you can't run in 32-bit mode under System 7. You can happily use System 7 with 8Mb or less, or use A/UX with more than 8Mb memory. I'm not sure, eventually there are other issues as well, but I would check the SIMMs to start with.
