I have a 2 meg DKB Agnus upgrade with the 8375 and was thinking about upgrading a Rev 5 A500 I have. I started thinking about, since the DKB only has an additional meg, am I going to end up with only 1.5 Megs of chip memory?
Yep.

I recall there was a hack to allow the A501 add on card to be used as chip memory Is this legit or just a passing legend?
Nope, it's real and necessary if you want a full 2mb Agnus scenario. May as well perform the hack since the 512kb memory in the trap door is slow Fast Ram anyway. lol  (no really, it is)

I have an A530 turbo that I am attempting to resurrect (missing the HD) and thought it would be a fun project to get an A500 with 2 megs of chip, 8 meg fast with the 030 precessor, booting with Kick 3.1 / WB 3.1.

any hints or tips are appreciated. The alternative is to use it in the A2000 with a Rev 6.2 and 1 meg already there for the chip memory.

thanks!

Wedging all that stuff into an A500... you're going to want a beefier power supply for sure, which an A2000 already has. There's definitely a coolness factor to pimping out an A500 though - so you're going to have to decide if that's something you really want to do. Stuffing a HD in an A500's case is kind of BS too, since you have to remove the A500's floppy drive. There goes part of the coolness or feel of the machine - unless you somehow wedge a 2.5" drive in there somewhere.
