OK, since I have no available user manual, and google seems to be less than helpful on this subject, can anyone tell me what each port on the back of my Altos 580 and 8000 is? For the 580, I've got figured out that JA is for a parallel printer, JB&JD are RS-232 and JC is the RS-232 console. What is JE? For the 8000, I've noticed that JU-JZ seem to be RS-232 with JX the console. What is everthign else? Does anyone have pinouts for ports that aren't 'standard' like RS-232 ports? Thanks for the help -- Pat
