With a KS10 you're limited on the version of
TOPS-20 that you can
run, I believe the max version is around V4.01. It can run TOPS-10
V7.04, and ITS. IIRC, only ITS supported networking on the KS10.
Yes, the KS is limited to TOPS-20 v4.1 (no double-digit version nos. for
TOPS-20), although my late friend once got 5.4 (with TCP/IP) running on
one. That work was lost more than 20 years ago.
ITS supports TCP/IP, but only over Chaosnet, as far as I can tell.
With the KL10B you can run through TOPS-20 V7, and
have DECnet and
TCP/IP support.
No TCP/IP on standard Tops-10, although I am informed by a reliable
source that it was done for v7.02, where it ran over ANF-10.
