Hi Gerald
I am repairing a Tektronix 2784. Therefore i'm searching for the Processor ExtenderBoard with the SerialPort or a Circuit Diagram for this.
I know it's a 85C30 Dual Serial Interface from Zilog and it uses &0100 to &010F to communicate.
Thank you for help. That's the first Time I'm using groups. I have some files with circuit diagrams, also Module Level Service Manual
Regards
Juergen
