For a time after SysInfo and some other system diagnostic utilities came
out there was a rash of callers to the various accelerator manufacturers
from concerned customers suspecting that they got a "low-quality" 68EC030
or 68EC040 chip.

The problem started with misinformation and assumption.

Back when Motorola first released the 68EC030 (EC stands for Embedded
Controller) it was described as a full 68030 with the MMU portion disabled.
This made the chip less expensive to produce and brought the price of
accelerators down substantially.  The MMU was "disabled" from the
production standpoint, meaning that it wasn't even put into the die.
Motorola did not make a bunch of 68030s and then cripple them after the
fact.  The 68EC030 is intentionally designed without the MMU.  It is not a
full 68030 that failed the MMU portion of testing, as some have wrongly
inferred.

The MMU is a component of the full 68030 and 68040 that is not necessarily
used, and the AmigaOS is an example of software that does not automatically
use it.  System information software accurately reported the MMU as
"DISABLED" (as opposed to "ENABLED").  Well, a lot of people took this to
mean that it was REMOVED from the chip and hence they decided that the
various accelerator companies must have slipped in an EC style chip
thinking the world wouldn't notice.  Many of the companies took upwards of
hundreds of phone calls per day with irate customers demanding full
processor upgrades.

They spent a lot of time and money telling people the same thing over and
over, "You have a full chip, you're not running anything that "enables" the
MMU, and once you do SysInfo will say so." Nic Wilson, the author of
SysInfo decided that he would change the wording to something a little less
confusing to the average user: "IN USE" and "NOT IN USE". Thanks Nic.

This is probably one of the many items that led up to the discontinuance of
live tech support from GVP.  When a company pays technicians to answer
questions like this all day, they lose money.
