SS/80 Exerciser

[magore]

I now have the files on my github page: github.com/magore/hp85disk under the lif folder
I found two errors 1 on track 11 and another on track 13
On track 11 sector 8 was missing but instead there was a unique sector numbered 116
On track 13 sector 11 was missing but instead there was a unique sector numbered 116
I put a bit of code in my teledisk lif image converter code to translate the numbers.

On my github project site the folder lif contains linux versions stand alone tools to manage LIF and TELEDISK LIF images (They can be compiled under cygwin or gnu for windows, etc)

I have included a copy of 85-SS80.LIF - I still need to check it - but I think it explains the
problem. Perhaps the original file had an error that when teledisk was used to create the original. The 85-SS80.TD0 file had a sector 116 on track 11 and 13 while missing a sector - unfortunately there is no way to be sure why that sector number exists (for example a read error when the person saved the original?) What is clear is that in both cases there was a missing sector in the 16 sector sequence that could be filled in by assuming that sector 116 was the missing one.

Code:
