Re: 10-15 million pounds
"I do object however to your suggestion that anybody ever got an ICL and IBM mainframe to talk to each other, in any meaningful and useful sense of the phrase."
Objection noted. A VAX equipped with SNA/RJE was a good way of talking to IBMs, and that apparently included getting two IBMs to talk to each other.
I suspect that many comms projects involving disparate mainframes of the era were quietly shelved in favour of existing tape based solutions.
