Following on from a previous post in which he showed how the Pi can be used to emulate a mainframe, Andrew Back has now moved on to describing how to turn a couple of Pis into a VAX cluster. He uses a piece of software called SimH to emulate the VAX hardware. Read more detail, including how to do it yourself, here.
Do excuse me, I may have had a little panic attack there. Still recovering from debugging C and Ingres on one of those beasts at the Royal Bank of Scotland twenty years ago. The first time any emulation project has made me think “Good Lord, for the love of God, no! Think of the children! This madness must be stopped!”
The VT420 terminal, on the other hand… happy memories of The Gold Key.
