That is an amazing resource. Just skimming Amiga mags and seeing so many different gadgets that aren't in the BBOAH or the AHD...wow. Like this one little sled that sat under an A500 and let you add A2000 cards, a second floppy drive, etc. (not the bogeda bay, this one actually sat underneath the 500 and the ad mentions the rather dubious claim that it's easier to type on the already uncomfortably oriented A500 keyboard that way).
