you like how quick the A500 is compared to the A1200? Does it have an accelerator sitting in the 68000 slot or what? If you plan on keeping the A1200's, I wouldn't waste my time trying to track down SCSI stuff, extra ram or accelerators for the A500. Much easier to procure that stuff (and cheaper too usually) for the A1200's. A500 is great for playing games off floppy. If you like to tinker, maybe build yourself an 86-pin expansion bus card to 100-pin Zorro adapter and throw a 2091 card on it or get one of my MrMKL's CF68kIDE adapters and putz around with that inside the A500...
