The reason why (according to icomp) the ACA1230 was shelved and no longer sold was far too many support cases where users had activated tuning options via the ACATune software and expecting them to work on their machines.
This was reported mainly from Kickstart 3.1 users so your mileage may vary with Kickstart 3.2. According to the icomp wiki, anything beyond Maprom, CPU cache (not chip cache!) and fastmem are considered "depreciated" and should not be used.
