The HDD was borked but it had a 3.5" bay that worked, so I got a floppy-based distro running on it. I later replaced the drive and then made the mistake of attempting to compile X11 on it. Results were... mixed.
X disks were X11. There were also the A,B, C etc disks.
Then there was the Coherent install, with massive manual on ultra thin paper with the shell on the front.
Ah, good times ;-)
