Hi Jedgell,
In my opinion, best thing you can do with the 1000 is get a second hand Viper 520 card. This will give you a turbo board, 3.0 or 3.1 Roms, 8 MB of Ram plus an auto-boot IDE controller. If you have a 2,5" drive you can mount that on the viper.
There are two downsides to this, though. It will disable the expansion port at the rights side of the 1000 and you won't fit the diskdrive in anymore.
An alternative is to use an A500 controller. The expansion port of the 1000 is pin-compatible to the one of the 500, only the expansions are turned around, since on the 500 the port is on the left.
Cheers,
Ron
