A few things to check: 1. No VRAM? The 7300 requires either 2-1 Meg VRAM SIMMs or all 4 slots filled in order to work. The pairs must be in their appropriate slots. 1 and 3 or 2 and 4 for 2 SIMM operation. 2. Are you sure you have a 200 board from a 9600? The 250 and faster CPU is the Mach V and not usable in the 7300. (250 and faster in the 8600 and 300 and faster in the 9600.) 3. Are you sure it is a cache card and it's in the cache slot? (in the middle of the RAM slots. also make sure it isn't a ROM SIMM stuck in the cache slot.) There were also some that included a ROM SIMM in a ROM slot. (by the CPU daughter card If memory serves) This may need to be removed with a newer CPU.
You may have fried the mb with a bad CPU, but the 7300's CPU will lock up during startup if no VRAM is present. The cache on the Mach V CPUs was on the CPU daughtercard, (one of the reasons they aren't usable in the older Macs) but the earlier 9600 CPUs (233 or slower) used a MB cache in a slot just like the 7300. If the PS works with the 7300/180 CPU, it will work with a 9600/200 CPU. Was everything working before installing the new CPU?
