Hm, back to the PC Harddrive !! You definitely have to use an A500 IDE Controller to connect a PC Harddrive to the Amiga (e.g. AlfaPower HD Controller which allready has the option for 8 MB FastRam btw.) These thingies fit into the Expasion Port on the left side of your A500. And if you want a faster CPU, as Akira allready said, buy yourself a Turbocard with a 68030, it is placed in the socket of your 68000 and makes much more sense then a 68000@14 Mhz oder a 68010 !! And it isnĀ“t expensive anymore
