Linked lists go back a long way. FAT is one, in a sense. DECtape file systems for DOS (also RSTS) are linked, in the blocks. The same goes for the CDC 6000 file system (more precisely, it has contiguous blocks within a track, and links from the last block in the track to the next track

Al is right. AFAIK, the CHM has never made an official announcement regarding the release of the LISA OS. Perhaps the confusion comes from this email from Al to the LisaList: -- Al Kossow Dec 24, 2017, 7:49:23 AM to lisa...@googlegroups.com Just wanted to let everyone know the sources to the OS

I keep finding articles about how The Computer History Museum will (note tense) release the Apple Lisa OS (office system) source code in 2018. I can't find any evidence that this actually happened. As a former Pascal programmer, it would be fascinating. Anyone know if this actually happened?
