Michele Magliocca alias Miky'060 on Amigaworld.net has still one Pegasos I for collection purposes, and he helped people in south Italy to build up and run dozens of Pegasos motherboards. So you can ask him for any info.
I think he has an account here too, but I am not sure. Also nowadays he is not anymore active as some years ago for MorphOS helping and diffusing the OS.
