A Slight Divergence

While I was recently recovering from the Plague know as COVID, I could not get enthusiastic about painting, so I decided to venture into the realm of vintage computing and assembled a replica of a 1970's minicomputer known as a DEC PDP-11. I had bought this kit a few weeks before with the intention of building it latter in the year.

The kit essentially adds a scale replica of the PDP-11's front control panel to a Raspberry PI single board computer which in turn runs an emulation of the PDP-11's operating system.

For a more in depth look, here is a link to the kit creator's website:

The finished article

It took three afternoon's of work to complete the kit, and I am quite happy with the outcome. I only made two mistakes - the white switch was put in wrong and one solder joint (out of 350+ ) was dodgy - but easily found and corrected. I have not done electronic work like this since the early 90's and actually enjoyed a trip back in time to an earlier part of my working life. There are some additions that can be added, and will look at doing that at a latter time.
