Hi Alain! I have a lot of document describing the Exorcizer, with complete drawings, software, firmware... I still have a complete machine (a wrapped clone, i designed in this old time! two versions: one with 64k cmos RAM, and one 64k with DynRam) I knew very well 6800, 6300, 6801, 6301, ... In that time i created a real time emulator for these uP. But the system is old and needs to be restored. (I have a lot of spare parts, including 4 8" floppy mechanisms) . I intend to publish the story of this home brew computer, but i need time... (CPU, terminal, graphic printer, digital cassette, floppies, magnetic card reader B7400, Eprom prog) This machine is aslo able to run original OS9 with a 6809/6309 cpu. I have doc, 8" floppies, listings... too much matter... that needs to be sorted. Follow-up in french? Still in Bordeaux? Have a nice day! JMP
