Hackshed crew has been working on a homebrew CPU from scratch in CPLD:
Building things on breadboards is fine but I often find that I either need to pinch something from the design, I knock wires out of place or there’s some other reason that it gets destroyed. In order to get round this, I’ve started building a modular control panel for my ongoing project. I’ve named it…. The Carlputer… ahem.
The first thing I decided I just HAD to have is nipple switches (toggle switches). I love the look of the old Altair 8800 and wanted to have something similar so off I went to Aliexpress and ordered 100 switches for £18. Bargain.
