Good old days when I transit from XA to ESA, from dos/vse to movs, from racf administrator to dB admin, Ibm start to ship 3390-3, ispf, Rexx to generate jcl, patching and debug 370 assembler ...

Still holding a Hp dos pocket whilst working on all these.

ThOse were the days. Different very much from using a mac to run leela zero using egpu :-)
