- Hi,
-
- I just bought an A4000. I was looking through the user's guide and it
- says.
-
- "A4000 models shipped with a 68040-level microprocessor on the
- processor module may have the 68EC040 variation of the chip. The EC
- chip omits the internal FPU and MMU present on the full 68040.
- ..."
- it goes on to say that the full 68040 would have dramatic increases in
- math operations over a 68EC040 68882 combination, and that the EC is
- chip replacable with the 68040 for those who want to upgrade.
-
- I'm kinda surprised... I got the machine intending to do some heavy
- math. I just assumed it'd be full 68040, especially after reading
- reviews and stuff on the net. Did this subject come up? Guess I
- should have done more research...
-
- How do I tell if I've got an EC? (can't open the box without voiding
- warrantee). Showconfig and CPU programs say I've got a 68040/68882.
- (looks kinda bad...though doesn't say 68EC040 explicitly)
- Are all current A4000's EC's or full 68040's?
- Does anyone know just how different they are? (besides no MMU)
-
- thanks
