I love the guys here that say the "timing fixes" is an "easy mod" far from..

Mostly agree here...
I got lucky with my MB and ACA1230/28.  It works well.
But when I was reading about the timing fixes people were doing, I was wondering if I was going to do that..
Probably..
I mean, I modded my A500 for 2M CHIP and I've done some composite video mods on some consoles, but I'm not that great with a soldering iron, so it would have been nerve wracking...

Although, to be fair, although Jens' boards are susceptible to the Amiga timing issue, it's not new.  The timing fix was needed for other accelerators.
Here's a 2003 post on Amiga.org about the fixes, and I know they well predated that post..

So, not getting an ACA won't guarantee that you won't need one, although the older accels were less likely to need them.

One thing to watch out for with some of the older accelerators is that some (just a few) of them aren't PCMCIA friendly.  So if you have one of those and a 3.1 ROM, you won't be able to use PCMCIA with 8M RAM in the accellerator.

I think there were just a few released that came with 8M and for some reason mapped it in the conflicting location.  (Probably released before 3.1, so it didn't conflict then..)
