I maintain the UK IMO Register, a listing of the
details of past UK team members in the International Mathematical
Olympiad (including both Cambridge’s 1998 Fields Medalists).
I am a member of CUAS (Cambridge
University Astronomical Society); I have never held any office in that
society but occasionally use the telescopes and have made available
here information on the history of the Northumberland
Telescope.
I’ve done a fair amount of work on the CUCPS (Cambridge
University Computer Preservation Society) web site, in
particular the information about
TITAN.
As part of my interest in computer history, I have also made
available here the standard
ECMA-10—ECMA standard for Data Interchange on
Punched Tape. The standards organisation ECMA produce computer-related standards
that are freely available both online and in printed form (even a
complete set of current printed ECMA standards is free); unfortunately
they cannot supply copies of obsolete standards such as this one, but
since their standards are not copyright it can be distributed here.
Many ECMA standards are essentially identical to expensive ISO ones; there are several ISO
standards for punched paper tape (numbers 1113, 1154, 1729, 2195 and
3692) but I have not checked their equivalence to this one.
