Trying to collect information about the Commodore 900 (to be emulated at some point in Xemu).

CPU: Zilog Z8001 (Z8000 variant with MMU). OS: Coherent (UNIX variant) Video: text-only ("server version") or 1024*800 mono ("workstation version") with VDC 8563 (what was in C128 too, basically this chip was designed for C900 originally, and later adopted for the C128 only!)
