if i do the aca timing fixes, do i need the accelerator in to run? are these aca only timing fixes?
No, after the fix your Amiga 1200 will work with and without an accelerator installed.
And no, they are not specific to the ACA series, they apply to all accelerator cards that require a fix.
As for the 040...a 40 MHz 040 card runs circles around any 030 card, but again finding an affordable one isn't easy. The 1232 @ 33 MHz is a nice card though... I have one myself.
