The donor Psion 5 are here. Managed to get two of them at only GBP50.

One of the units suffer the dreaded ribbon problem, and is most likely going to be the device that will get the electronic makeover for the project.

As the other is fully functional, I will be having it as my work unit, so I can see how nice it is to have as a daily driver for word processing on the go.

As i have the units in hand, I can now plan and decide what will go where in the build. Plans may evolve along the way, but hopefully everything can go as smooth as silk. I hope.
