Wanna know about mainframes? Together with a few S/370 enthousiasts we started a wiki to spread knowledge about the Hercules 370 emulator and the Operating Systems we can run on them. Click here for the 370 wiki.
I kept a couple of Reference Summary cards from ancient times. I photographed them to be shared with the community. See the cards themselves here.
Today I automated the process of printing MVS output from the Hercules emulator to PDF files. It makes it much more realistic and nostalgic to look at output on the old ‘zebra-paper’, don’t you think? Example below. Also check my
Today I got my copy of MTS (Michigan Terminal System) and installed it in Hercules on my Raspberry Pi model 2, using the try-mts cookbook. See this page for more info on MTS. Below you will find a screenshot of
Finally, ready, my IBM S370 OS’s are live again. It took some tinkering to get them running on the new SSD drives, but here we are:
After a crash yesterday, my ‘datacenter’ is up again. I took the time to alter the setup. It’s not on my desk anymore… 😉 Here you see the login screens for my two Ma’c (top) and three Raspberry Pi’s (bottom).
Today I built my ‘datacenter’… Three Raspberry Pi’s that will form a stack of ‘power’ to run System/370 Operating Systems… For a full photo report see this link.
8 bit computer, microcode challenges My 8 bit instructions can have up to 8 microcode steps each; I defined up to 24 control signals (thus needing 3 bytes per step); So in the Arduino Nano I’m using, I have to
