How to Build a Mainframe

How to Build a Mainframe. Mainframes are powerful, special purpose computers run mainly by large organizations that process large volumes of data such as census or financial transactions. They're built to be reliable, secure and capable of supporting enormous input/output rates and can operate as multiple virtual servers. They're too much for home and very expensive. To build one from a home PC is extremely difficult; it may be easier to buy a new one.

Step

Build the motherboard. Convert your home system into a multiprocessor platform to give it mainframe-class performance. Build it into a 64-bit system if it isn't one. Add to it 8 gigabytes of RAM.

Step

Add to it an older tape drive such as the 3490. Attach it to the cable and binder twine on the motherboard.

Step

Attach disk drives with at least five new modes. Different disk drives are meant for different functions.

Step

Install several operating systems. You might start with z/OS, z800 and Linux. Linux, being open source, is freely downloadable.

Step

Connect an input console to the system. In the case of the mainframe, it means a display monitor and keyboard combination. This is the instrument panel that allows the user to interact with the mainframe.
