Computer Operating Systems

This is a list of the operating systems I know. Each list is in descending order of current familiarity. For a few of these my familiarity was only as a user, but for most it went further, as a system administrator and/or application programmer. I have even written device drivers and system extensions or customizations for many of them.

UNIX variants

NetBSD
FreeBSD
Linux
SunOS 4
BSD 4.3
BSD 2.9
SysVr4
Ultrix
6th Edition

Other Operating Systems

IOS (cisco routers)
RT-11
CGW (MIT gateway system, also used by Proteon)
LispM
ITS
RSTS/E
Genera
RSX-11D
VAX/VMS
AmigaDOS/Intuition
Multics
DSM-11
RSX-11M
CP/M
DOS-11
TSO

Plus, batch operating systems from NCR and IBM. I'm not sure they had names, if so I've forgotten what they were called.

Additionally, I have written several from-scratch operating systems for real-time embedded controls as well as working with several that others had implemented.

And finally, a random note:
I'm sure my memory used to be better. But, I can't seem to recall what that was like.
