Corestore Collection - IBM System/390

Placeholder page for S/390 stuff


S/390 Integrated Server 3006 which sometimes serves the Corestore pages:



IS 3006 is a big black anonymous lump




IBM SSA drives ($12,000 per 18GB drive!) not used - SCSI ServeRAID used instead.




Rear - big blue cable is channel (Bus & Tag); five network cables - one ethernet for front-end OS/2, three for S/390, plus a toekn-ring for S/390.




Boards...




Closeup of rear connectors




An S/390 console with a view (Empire State building in background :-)




3172 - IBM network processor




Cover removed, front panel...



Bus & Tag in from mainframe, multiple ethernet out.




Inside it's pretty much a Microchannel PC, with a special operating system - even has keyboard and video ports.




IBM 3174 Establishment Controller - this lets IBM 3270 terminals talk to the mainframe.




Front panel.




Rear - this one is maxed-out with interfaces, can talk to the mainframe via Bus & Tag channel, ESCON (fibre) channel, or ethernet.




My old P/390... a microchannel IBM Server 320 with a microchannel 128MB P/390 card installed...
