HP 2640 character set generation manual in the UK

[CuriousMarc]

The link below is from the computer museum in Cambridge, UK, which seems to
have a copy of an HP 2640 terminal manual I am looking for. Is anyone from
that museum on the list? Does any of the UK members know them?

Does anyone on the list have a copy of this manual?
