ADDS Multivision

Hi! I have in my basement a genuine ADDS Multivision machine. It's runs a multitasking version of CP/M, called MUON, and used to run brilliantly until I accidentally ran the SYSGEN utility which, I found out later, overwrote the config information. It now refuses to boot, saying "Stack error" or something equally useful :-( Has anybody heard of this machine before - or, even better, does anybody have boot disks for MUON v2.3 ?? I would phone up ADDS, but they're in America and I don't particularly fancy all the international phone calls from the UK! I don't have their address or fax number or anything - and that's not even mentioning the fact that quite probably, nobody there will know a thing about this machine! :-( If any of you can help in any way, it would be much appreciated!!
