The Cache Comparators are long since discontinued but...i have a source, and there are more than a few!

Asking around suppliers for the MC68030FE25 - anyone know the difference, if any, between the -B and -C models? Just revisions?

Kai, no sense to search for this particular device - probably any TAG SRAM from PC can be used - probably there is some change in code required but anyway PAL's should be replaced by one CPLD, also probably some memory (32 bit, modern SDRAM or at least FPM/EDO) should be added so in total CPU + CACHE + MEMORY.
Probably large part of Amiga memory map must have cache excluded thus i would rather focus on very fast normal memory - today perhaps even single cycle up to 50MHz (assuming 100 - 133MHz clock +2.5 cycle latency from average SDRAM).

Also TI offer BCT version for such TAG SRAM.
