To my knowledge there is no speedup or stability change between 8372B (or AB) and 8375. Don't trust that list,i don't think the 8375 pinout matches the 3000/T machines. There was no pal only Agnus as far as i know for the 3000,they were always pal/ntsc capable. Only 8372B and 8372AB worked in the A3000/T.
Buster 11 only allows for 1 Bus Master. I think Buster 9 allowed multiple bus masters but was slower over all.
Hopefully Haynie comes thru with a Buster 12 some day!
