I don't recall much written documentation that came with the Demo disk
I believe there was a cassette audio tape with Howard giving his instructions,
Your also looking at a very early version of Validator, with a short lived
final readouts screen, The demo disk is Val 1 which was quickly updated
to Val 2. Later with Ted's help came Val3 and then Val 4 or Val2006
BTW You are going to get some strange results because Ted had to upgrade
the speed rating calculations in 2006
I believe the results for the demo disk races are in one of the follow ups
I will see if I can find which one, However I have a suggestion,
I suggest you get a RDSS trial and download the FREE sample data cards
Ted provides
You can set RDSS to mirror Validator and It will be much easier to learn and ask questions about the methodology using a 2016 program
I love validator so I will always help if I can
just ask away HERE
