This is by far the most in-depth walk through of the earliest 86-DOS (pre-cursor to PC/MS-DOS) that I've seen. Hardware history walk through, live code walk through porting code from Z-80 CP/M to 8086 86-DOS. Very well done #RetroComputing #ComputerHistory #history #86dos #cpm
Showing how to use the Earliest known copy of 86-DOS, the antecedent to IBM PC-DOS. (MS-DOS)
This video gives an in-depth look at what is currently the oldest known copy of 86-DOS, the antecedent to #MSDOS aka #PCDOS, where we go through the process ...YouTube

This ACM post by Kode Vicious brings up constraints on modern software imposed by antiquated POSIX compliance notions. The conclusion is we need to work on newer paradigms that are better suited to how computers are built today: with dozens of processors of varying types, multiple levels of caches, very fast storage combined with slower storage etc. I totally get that. I just assume that researchers are working on that and nothing has proved compelling enough to rise to mainstream use. Am I being optimistic in that or were the last big innovations in operating systems and software engineering 30 years ago? #programming #SoftwareEngineering #research #OperatingSystems #posix #unix #linux https://queue.acm.org/detail.cfm?id=3570921
