Much later in the year 2000 there was the 8-Bit Construction Set record: http://www.beigerecords.com/products/beg-004.html

It had Atari and Commodore music (as audio) as well as Atari and Commodore software (as data).

Despite the claim on their old page to be the “first use of vinyl for software distribution” they did later acknowledge and reference some prior art in a Slashdot thread: https://slashdot.org/comments.pl?sid=140154&threshold=-1&com...

This might be it, but I'm not 100% sure, my memory is not what it used to be, there are also a few other good answers.

I wish HN would let you search upvoted comments and submissions, it would revolutionize my life since I can remember previous things I've upvoted, but have no easy way to find any of them. I might sit down one day, and manually export all my liked comments and subscriptions.
