The board is a copy of the 16 Bit Board from Zilogs System 8000. Some parts where added because the subsystem design is different (serial ports, harddisk, floppy disks instead of tape,...). WEGA only runs on a Z8001 (no Z8002) and the OS was able to execute (and compile) segmented (full memory access) and unsegmented (only 64K access iirc) binaries. The OS of the P8000 is as I said a copy of ZEUS. The name ZEUS was "replaced" with WEGA in the executables (hex editor). Some parts of the system where reverse engineered and altered. I had contact to a kernel developer after the system collapsed who told me some stories ;) While the userland ist nearly a 100% copy of ZEUS, main parts of the kernel (dev) where changed to handle the different system layout. I own a complete and running P8000 as well as a S8000 which could run if I would have a) a copy of the Zilog ZEUS Installation Tape (+ system diagnostic tape) b) a working tape drive (non-standard tape not compatible to something else) c) a SA1100 harddisk, or c) a SMD Controller + SMD disks. d) time After I designed, built and programmed a harddisk subsystem emulator for the P8000, I also planed to emulate the whole disk subsystem of the S8000. Additionally I planned to use a partial backup of a ZEUS installation I have + WEGA to generate a running ZEUS-a-like but then I became a father and time was gone ;) So right now my S8000 sits in my basement togehter with some circuit ideas and logical analysation results and waits for more time ;) Some links... Kernel Sources of WEGA I could get my hands on, or are disassembled and "make-it-C-code-again"ed by me https://github.com/OlliL/P8000/tree/master/WEGA/src/uts Beside that there is also other stuff like C compiler sources and so on - just navigate around :) Zilog S8000 pics http://pics.pofo.de/index.php?/category/129 EAW P8000 pics http://pics.pofo.de/index.php?/category/21 Some S8000 sources (mostly firmware, rebuilt with having access to the P8000 firmware) https://github.com/OlliL/S8000 Any questions are welcome....
