Well, I called out terms such as Virtual Machine / Conversational (Cambridge?)
Monitor System / System Product / High Performance Option and got back the
over the telephone equivelant of blank looks and questions about whether the
hardware involved was a PS/2 (it was an Amdahl 5870 but we had an IBM
software support contract).

I must have managed to get the message through eventually though because
some time after I left that job, my former boss told me that IBM got back
to them with a workaround for the issue I reported.
