Apple's refusal to document the system was one problem. Another problem
I had (that I started griping about during the A/UX 3.0 beta test) was
Apple wouldn't let the engineers support the GPi pin on the serial ports
under A/UX because not all Macs had the GPi pin. I continuously pointed
out that all Macs that could run A/UX *DID* have the GPi pin, and they
could allow this to be a configuration option. Without the GPi pin there
was no way to have secure dial-in and hardware flow control, which means
you really didn't want to have a dial-in connection on your A/UX system.

There's a lot of other ways Apple mistreated IIfx owners.
