I was recruited into a project that was providing lots of new UNIX kernel support to a HP-UX 7.0 environment on a 68030 CPU. I had to port Mentat System V Streams, an HP-UX 9.0 multi-LUN SCSI driver (backport by me to 7.0), X.25 Level 2 and 3 support code from Spyder and cobble up a tunnel driver to hook the new Mentat Streams into the BSD TCP/IP stack. Over 6 weeks I ported and integrated 275,000 lines of new code into the kernel. At the lowest level, I needed to use 68030 assembler to leverage memory "test and set" instructions to ensure atomic locking of data structures.

When I finished the task, my company took the new OS to a computer show in Europe to show it off, then a week later an earthquake hit Haiti. My code was in the field providing support for military activity to support the rescue/recovery efforts. No AI in those days. Just hours of grunt work making that kernel code bullet proof. The "magic" under the covers that lets people to the high level stuff with ease.

The 680xx family was the best there ever was! Too bad that Intel blight was adopted for use in the PC.
