Maybe come back when you have an A500 & have tried cramming in multiple upgrades inside the case. A megachip and 1.8mb trapdoor expansion with a gary tower of death takes up a lot of the room.
I agree with this statement. Once you have a kickstart switcher, indvision and MegaChip installed in your A500, you will start getting a little sick of internal mods to the A500 (no room).
I don't mind internal mods, but the side expansion port on the A500 was a great design feature and should be used. It makes installation/removal of components easy, safe and plug-n-play.
Besides - A500's with sidecars are COOL!
As for this not working in an A2000, well, since the side expansion port of an A500 is almost a Zorro slot, I'm sure with a simple adapter it could be made to work on an A2000, or the design could be used to make an A2000 version (perhaps with some lines leading to the A2000's CPU slot).
