I am proud to announce that Volume 4, FYSOS: Input and Output Devices, is now available.
This volume has information on different forms of mice and keyboard input and Sound Blaster output.
I have to admit, this was probably the most enjoyable of the series. I worked with older hardware with little to no documentation and got it to function.
Most of the documentation in this book may be outdated to your liking, except for the PS/2 support. Hence, I put a lot of work and effort into documenting this part. This book will show you how to communicate with a PS/2 style keyboard and/or mouse. The remaining chapters are mostly for enjoyment, at least for me anyway.
Thank you everyone for your support.
