macintosh SE/SE 30
Released at the same time as the mac II, (march, 1987) the mac SE further addressed the issue of expansion. It came in a new platinum case, had an expansion slot, and included a bay for either a second internal floppy drive, or an internal hard drive. The mac SE was also one of the first macs to include the apple desktop bus (ADB), which allowed for up to 16 input devices.
The SE/30 was essentially a IIx inside an SE case. The second floppy feature of the SE was no longer offered in the SE/30, in favor of a built-in hard drive. Since the ROMs were not 32-bit clean, a software enabler is required to access more than 8 MB of RAM.
