I can confirm most of that is true. I was the one that added the two 040 processors (no MMU), the idea being that AMP is part of the Amiga DNA and the 040s would be dropping in price quite drastically by the time we'd go to manufacturing. Of course I didn't call it AMP at the time. I did replace the SCSI with dual IDE controllers (one per 040, up to 8 devices), IR port on the front, 3.5mm headphone jack next to the mouse and joystick port on the side. You should see the machine the engineers were trying to construct. :rolleyes:
I was one of those "Will Hunting" janitors at C= at that time. The engineers would struggle all day, and then at night I'd go in and solve the problems. They'd come in the next day and would be amazed. They never found out who did it, but they weren't about to look the proverbial gift-horse in the mouth.
