If you think $80 for a MegaChip is "pricier" then you should not be in this hobby. Anyway, who really needs more then 1 mb of chip ram on an Amiga 500.
$80 for a MegaChip is "pricier" than a whole rev 8a board. I've personally spent thousands on Amiga stuff (having had one of each released system plus PPC boards,) so I'm not complaining about the cost of a MegaChip, just trying to eliminate its need in my application. I wanted 2MB Chip ram on my A500 to go with the '030 accelerator and ethernet board while running AmigaOS 3.9, it was an exercise in maxing out a non-towered A500. Sure, I could've just used the 3000T or 4000T with '060s, but it was a fun project.
