- First, the lower of the two IIsi configurations isn't a 3/80, it's
- a 3/40. Beware of 40mb hard drives. They're too small.
-
- The hardware differences between an LC II and a IIsi:
- a) LC II runs at 16MHz, IIsi at 20MHz.
- b) LC II's built-in video doesn't support a full page display.
- The IIsi's does. The IIsi uses system RAM for VRAM, though,
- while the LC II has separate VRAM.
- c) The IIsi has the "one button turnon", whereas the LC II has a
- power switch on the back AND a power switch on the monitor, and
- the LC II doesn't have a power plug for the monitor on it.
- d) The IIsi has a full 32-bit data path, the LC II a 16-bit path.
- e) The LC II can use a maximum of 10mb of memory. The IIsi has a
- practical limit of 17mb using 4mb SIMMs. (Theoretically, you can
- drop 4 16mb SIMMs in a IIsi, though.)
- f) The IIsi has a much more useful expansion slot, although you have to
- buy that stupid adaptor with the math coprocessor on it. The only
- things I've seen that go in an LC II's slot are the Apple IIe card,
- math coprocessors, and ethernet cards, choose one (1). At least with
- the IIsi, you can get the math coprocessor and still have a slot.
- g) The IIsi can run A/UX.
-
- You can definitely feel the speed difference between the two machines.
- But it's that THAT different. The reasons I'd buy the IIsi over the LC
- II are the real expansion slot, the ability to put more memory in the
- machine and the convenience of the power switch. The LC II's not a bad
- machine at all...I've sold about 80 of them to students in the incoming
- class here. But it ain't a Mac II. :)
