No, that's closed source and only available as a demo iso but it's known to work on real hardware and freely downloadable so is a good test. (AFAIK those who developed MorphOS had close connection to those who wrote the firmware for Pegasos II.) Maybe the VT8231 datasheet or similar parts (we only emulate VT82C686B and VT8231 in QEMU) has some info on this. Regards, BALATON Zoltan
