Some of you might be aware that I have written a computer program to generate freight movements on the PLR. However, that requires me to run the program on my laptop, generate the freight movements, print out the manifests and then use the print-outs to guide the movements whilst out in the garden.
Recently, I stumbled across my old Psion palmtop computer tucked away in an old computer bag at the back of the cupboard under the stairs.

Remarkably, after inserting a couple of AA batteries, it sprang into life. I loved (and still do) my little Psion which, for the uninitiated, has a rubberised keyboard, a small LED screen and built-in word processor, spreadsheet, database, agenda, clock and world time apps. It also has a very accessible programming language based on OPL. So, I dusted off my OPL programming knowledge and decided to write a version of my freight handling program for the Psion. This means I can now take the computer in my pocket out into the garden and manage freight movements on the fly.
I suppose this is a case of retrotech in action.
