The title says it all. Just a pedantic/cultural question. How many types of Amiga PSUs actually existed? I know of four types:
"Power supply A300": switch on the bottom half of the PSU, slightly on the left
"Power supply A600": switch on the upper half, centered
(dunno the designation): switch in the top right corner
"Power supply A500/A600/A1200": the A1200 one, smaller, switch centered on the bottom half
Were there another ones?
