Ah, Interesting memories. I worked on Beltel for a while, which was a South African copy of the UK version of this. As in, South Africa got a copy of the code, and developed from there. Ran over ordinary telephone lines using mostly 2400 baud modems to a client which was normally a terminal program running on a PC. The code itself was VAX Pascal running on a set of DEC VAX VMS boxes (5 front-end boxes, and a dual-VAX backend cluster).
