Not sure, I believe my governor nicked it from somewhere and later got sussed, end of the line. Maybe you did write the original but I don't think that was the version we sold. Take it up with my good old mate Vic Cedar, difficult now as he has retired to the USA.
As I remember it the system I made was simply a connectivity one however I do believe a program was written to convert CPM format to DOS format and I've no idea were that came from.
Answers please, I still have contact details for the said Mr Cedar and we have chatted this year but he still makes no more sense now than during the time I worked for him. Barking comes to mind, but like us all he feels he is 'doing alright'.
