Learning Company software has been pretty well archived at this point. To me, the easiest approach would be to hold onto the original box/packaging for sentimental purposes, and just find a copy of it on a site like the Internet Archive.

If your goal is to use it on a period-correct system, I’d go with 34/40pin adapters that lets you read flash cards, USB, etc.

A lot of my friends have kept their old 486 computers, and everything is period-correct except for the hard drive and floppy drive which have been replaced with a CF-to-IDE for the HDD and Gotek running FlashFloppy firmware for the 3.5".
