English Amiga Board - View Single Post - Project: Making A600 as A500-compatible as possible

This would be a fun little project...

I have a rev 1 A600 with kickstart 1.3 and no RAM upgrades nor HDD, it's kind of good for old demos and stuff.... But I do get some glitches here and there, so I see it's not that compatible after all. I mean, quite often too, so there must be something in the newer platform design ruining the good old A500 compatibility. I've exchanged all the caps and stuff, so it's not that.

(Can I piggyback custom chips on top of others, or does this act as bitwise OR, thus the bottom chip will ruin it all?)
Any way to take a Denise from an A500, make a PLCC adapter and fit it in an A600? Same for Fat Agnus, if needed. Do you think this would solve the graphical glitches I am getting on certain demos?

Any ideas or comments on this? The only reason I have the A600 is because it's like a tiny A500, thus I want to make it as compatible as possible -- no matter what I have to do.
