Several years ago, Lyle Bickley began negotiations with S&H Computer Systems
to release TSX-Plus (a 3rd party Multiuser Operating System for PDP-11's) as
free software for personal use. As is often the case, this process can take
a lot longer than one would expect.
Once Lyle obtained an initial agreement from the owner of TSX-Plus, he then
had to await the approval from S&H's Board of Directors. Initially, S&H
chose to only release the source code listings for TSX-Plus (which are now
on Bitsavers.org). Unfortunately, the machine readable source code itself
had been accidentally lost when S&H changed PDP-11 computer systems
Eventually, Lyle was able to obtain the original SMD hard drive from S&H
containing the latest versions of TSX-Plus, and the layered products
COBOL-Plus and RTSORT (and other software that remains private to S&H
Computer Systems). He transferred the TSX-Plus, COBOL-Plus, and RTSORT files
to an RL02 disk - and using S&H's proprietary licensing software created a
"personal use, serialized version" of TSX-Plus. This version has ALL the
capabilities and features of the commercially licensed version of TSX-Plus.
Subsequently, Lyle was authorized to release this "Personal Use" TSX-Plus
distribution only to individuals that he could vouch for as being
After another year or so, he was able to obtain the current agreement and
license to make this "Personal Use" TSX-Plus distribution generally
available for non-commercial use.
Please note that TSX-Plus is NOT public domain software; S&H retains all
rights including ownership. They have provided a free personal use license
available through Bickley Consulting West. There is still a paid commercial
use license available directly from S&H.
We all owe a big "Thanks!" to Harry Sanders at S&H Computer Systems and his
Board of Directors for making this release a reality for all vintage
computer folks! Also, the hobby owes huge thanks to Lyle Bickley for
tirelessly pursuing this for us all! I've always been a huge fan of TSX-Plus
and I'm thrilled there's now a personal (hobbyist) license thanks to Lyle.
