a lot longer than one would expect.
Once Lyle obtained an initial agreement from the owner of TSX-Plus, he

to an RL02 disk - and using S&H's proprietary
licensing software created a

available through Bickley Consulting West. There is still a paid
use license available directly from S&H.
We all owe a big "Thanks!" to Harry Sanders at S&H Computer Systems and
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
