Fixed my second VDU connection

After pulling my hair out as to why I couldn't get a second port working, I posted the question to the Nixdorf group on Linked-In.

Quick as a flash Malone came back with some useful technical information about cable part numbers to use, which whilst completely different from mine I was still pretty sure that my wiring was correct, and also made a comment that the second ALME channel on the first ALME is reserved for the remote support connection.

I'm sure in the past I've used this channel for a normal VDU connection, however, it was worth a try.

He was dead right. So, another useful lesson learned.

Thanks Malone for the valuable info.

    I'm a software developer, an engineer and I love vintage computers, but the 8870 has a very special place in my heart.
