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).
8 bit computer, progress on the Control Unit Below some pictures of the progress of the construction of the Control Unit of my 8 bit computer. Two pictures, one of the front and one of the back. I’m not satisfied
8 bit computer, solution for the microcode As I mentioned in this post, I was looking for a solution to program a couple of EEPROMs that are going to hold the microcode for my 8 bit computer. Using an Arduino
8 bit computer, building up the Control Unit Here’s the start of the building of my Control Unit:
8 bit computer, storing the microcode, solution I have a solution for the micro code predicament mentioned before. I’m using an 8KB EEPROM memory chip (the AT28C64). These memory chips will be divided into four segments, each holding pieces of microcode. Decoding
