System zTidbitz
zTidbitz are a collection of condensed or summary information on a wide range of z/OS and System z hardware topics. You can think of them as "cheat sheets" or reference sheets in that they greatly condense considerably more product documentation. So they leave out a lot of detail and subtleties, but nevertheless, they can be very useful if you need a reminder or quick review of a topic area you are somewhat familiar with. Enjoy!
