No the VECTOR does come in various configurations including a 68EC030.
In fact the photo on the box shows the EC version. The label on my
box indicates that I have the EC version and I'm not certain but I
think my chip is labeled EC (I'd have to pull the board to double
check). The VECTOR does have a feature that allows it to copy
Kickstart ROM into 32bit RAM without an MMU. The User's Guide
recommends using this even for those with the 68030 because it's
faster. I've tried turning this feature off on reboot but still get
indication of the presents of a MMU. I guess there are three
possibilities.
1. SYSINFO and SHOWCONFIG aren't capable of differentiating between a
68030
and a 68EC030 on a Vector board.
2. The FASTROM feature of Vector is tricking the programs into thinking an MMU
is present.
3. Some cluts on night-shift mixed a 68030 in a batch of 68EC030's before they
were labeled.:)
I guess I'll start running ENFORCER and leave the CACHE's on unless I develop
a problem (Even ENFORCER reports that the MMU is ON when I run it!!!!????)
