A short time ago I was brought into a project with the scope to implement custom building automation (blinds that would track solar zenith) via a C-Bus Pascal Controller. That particular device was not my area of expertise at all, but was a nice trip back to my childhood language familiarity.

As far as I can tell, that device is still a component that can be purchased new: https://www.se.com/my/en/product/5500PACA/cbus-pascal-contro....
