I think you are referring to the old ACM SigAda Ada Letters articles by Karl Kuberl and Wolfram Pietsch on their ISAM implementation. They are on the ACM webpage. 

Here are the direct links to the PDF files (need to rotate the view 90deg, btw):

"A Portable Ada Implementation of Indexed Sequential Input-Output"
[Part 1/2] https://dl.acm.org/doi/pdf/10.1145/381943.381955?download=true 
[Part 2/2] https://dl.acm.org/doi/pdf/10.1145/9305.9306?download=true

I only skimmed the articles. Doesn't appear to be a way to get their implementation... Maybe email them?
