Greg,
a long time a go while still working for Computer Division of Philips Electronics I used
X.25 and X.21 extensively on various proprietary O.S.-es. X.25/X.21 (or PSDN/CSDN) was
used for Teletex (CCITT T series, TTX, better than telex but lost to FAX which was easier,
cheaper and legally acceptable).
I still have some dedicated boards which Philips used for X.25, X.21 and SDLC. At a
customer side in a test environment with SCO UNIX 3.2V4.2 SDLC links are still used, X.25
was phased out a few years ago. Same with DEC Tru64, a multi-port SYNC-2000 with
appropriate DEC software could support both X.25 and SDLC. AlphaServer DS25 with SDLC
links still in production.
I still have all the applicable software for SCO UNIX and DEC Tru64.
Consider uploading to archive.org or somewhere.
I've uploaded the SunLink stack here http://iommu.com/sun/sunlink-x.25-8.0.2.iso
There is a hobby x.25 network at https://x25.org/
Cheers,
uncle rubl
