Stripboard Magic is a Windows application for designing PCB layouts on stripboard (aka prototyping board). It was released by a British company called Ambyr which ceased trading a long time ago. The interface is a quite primitive and a little strange but the program is functional even on Windows XP. It also works great in Linux using Wine.
It can be a handy program when called upon and I have successfully used it a few times when throwing together random small circuits. Due to the interface I would imagine it to be a bit clumsy for very large circuits. The biggest gripe I have with it is the inability to change the orientation of components on the board, so some circuits tend to be slightly larger than they need to be.
I downloaded this copy of Stripboard Magic 1.0 some time in the 90’s and recently just found it lying about on my computer. I would consider it to well and truly be abandonware and as it seems to be a little sought after by some hobbyists I have provided a link to download it below.
Stripboard Magic is limited in functionality, it’s routing isn’t terribly efficient and some people have even found mistakes. If you want a better product and are happy to pay for it then I would suggest LochMaster.
