An A1200 with a Viper 030/28, 18mb and 4gb compact flash.
An A500 with some ram that I have basicall turned on and looked at the kick1.3 screen and then turned it off, has a leaky battery though that I need to remove
And an A500+ has a ram upgrade in it but tbh, Ive not done anything with it yet.
Theres also a hard disk for a 500 and a sidecar ram expansion.. Should try them all soon really.
Originally back in the day, An A500, 1mb, kickstart 1.3.2 and an external drive.
