I have a piece of hardware you dont list.
Made in Australia for the A500.
Axram 4. (I think)
Trapdoor card for ALL A500 revisions, gives the A500 the capability of 4x PC 1MB SIMMS. Also links up to the Agnus chip with a daughter board that slots into the agnus socket and the agnus chip slots into the daughter board. The card can be used in 2 or 4 meg modes, and if used with a specific Gary chip, can be used to give an A500 2MB of CHIP RAM using part of the simms address space as CHIP.
I dont have a digital camera, but its on the "To get" list.
