An Introduction to CP/M
​
CP/M was the first operating system for microcomputers in general use. Before MS-DOS gained dominance in the 16-bit microprocessor world, Digital Research's CP/M ruled the market for 8-bit machines.
​
A very quick introduction to the history of CP/M, followed by short how-to guides to use CP/M on an emulator and learn the basics of its command line and main applications. ​

CP/M Internals
​
The reason people are still drawn to CP/M is because it is so easy to fully understand the system, up from the tiniest detail. Yet, CP/M is the direct predecessor of MS-DOS (which was modeled very closely after CP/M) and has full functionality for normal use. If you know CP/M, you understand the low-level basics of any PC, and it gives you a level of understanding of the hardware that you'd never gain with, for instance, Linux.
​
In short, understanding CP/M is relatively easy, and it gives you an insight in today's computers that is hard to obtain in any other way.

Homebrewing Tools
​
Part of the fun with Homebrewing and fixing old computer stuff is that you can play with tools. Tools Are Nice. Every man needs them. Here are the favourites I picked up along the way.​ There's no particular point to this page - but that's true for the wholy hobby so why start apologising for that now?
