In this journal entry, for #DOScember2023 I'll be exploring Digital Research's Concurrent DOS, a multitasking and multi-user operating system that ran on PCs and was compatible with the PC platform. It's basically MS-DOS but with 4 concurrent sessions. I won't be exploring the multi-user aspect of it, but will take a dive into how it works. I wish I had it back in the early 80's (first version came out in 1984 and the version I'm looking at came out in 1987).
