Re: Luckily defence is comparatively easy
"If a simple CPU can be designed by a small start-up in the 1970s you surely can do it, too."
1970s was towards the end of the era of 16bit computers such as PDP11 (on a single chip towards the late 1970s?) and the start of the era of 32bit computers such as VAX (initially in the late 1970s occupying several 19" racks filled with hardware).
I do appreciate where you're coming from, but what software are you going to run on your 'simple' PDP/VAX era CPU.
I like RT11. Is there a torrent client for RT11?
