My 565 went very quickly away after I got a 568. Despite it being an immense improvement over its predecessor when it was new in the 90s and having fitted the Z board, I couldn’t have gone back to it even in a second system.
G68 has no issue at all with 96k, although you can’t get 96k out of it except with MHR. Fine for DSP33s, annoying for other purposes.
