Okay Fedi, momma needs some #electronics help
I am restoring an IBM 3279 color mainframe terminal for what will be the greatest prank I'm the history of IBM teleconferencing. But the on board battery is dead like Tupac and the Real Paul McCartney. Is there some way for me to make an appropriate replacement at home using AAs and a breadboard?

libzpc - A Protected-Key Cryptographic Library 1.3 + 1.4:
libzpc version 1.3 introduces a new protected key origin called ultravisor retrievable secret. You can use protected keys derived from retrievable secrets for encryption and decryption (AES), and for sign and verify operations (ECC) on an IBM z17.
libzpc version 1.4 supports new types of protected keys from origin retrievable secrets:
full-XTS and HMAC protected keys. New groups of function APIs are provided to run on an IBM z17
to perform operations with these new key types.https://www.ibm.com/docs/en/linux-on-systems?topic=linuxonibm/lxpc/lxpc_linuxonz.htm

Last summer I had the opportunity to attend Hot Chips where I saw the announcement of the IBM Telum II and IBM Spyre Accelerator, both of which bring piles of innovation to #IBMZ around #AI 👏
In October I actually got to hold an IBM Telum II wafer 😍
What's next? IBM Z Day Special Edition is coming up on April 8th, and there's an AI & Data track where we can learn more about how to use this fancy new hardware! 🎉
