Hello together, this week we had the topic "The Mainframe Architecture" in our knowledge sharing session. Elizabeth told us, that there are also training slides public accessible. I have added this link to our wiki page: https://www.ibm.com/training/pdfs/The_New_IBM_z15_A-technical_review_of_the_... That is a small (but also good) overview about the latest Z15 architecture. There is also a bigger set of technical instruction slides available. Elizabeth has received them and wants to make it public. I want to wait with that because of these default restrictions in such presentation slides: International Business Machines Corporation. No part of this document may be reproduced or transmitted in any form without written permission from IBM. We can publish it as part of our ZSystems team at this point, if we are receiving a written approval from IBM. I am happy, that the author of the bigger (training) slide set is open to forward them. Best regards, Sarah P.S. I have added also a YouTube channel Fit4Mainframe in our wiki. That has been created by one of the leading guys of the Academic Mainframe Consortium.
