It'd help you no end to be able to find information on-line to help . . . . try-
The Big Book of Amiga Hardware, in particular their info defining the differences, i.e.-
A1200HD model and the accelerators that there are to choose from-
A1200 Accelerators.
Many have expanded their A1200s though the use of
Tower cases that, although costing money, can simplify the adding of expansion slot-busses, drives, and heftier power supplies! The original Power Supply soon comes up short if even extra Hard Drives, or CD-Rom Drives, are added to an accelerator!
