Welcome to Nathanael's Gopher Space
==================================

This gopherhole is a home for my retrocomputing projects,
research notes, and software development.

Current interests include:

 * BetterCP/M
 * CP/M 2.2 internals
 * Z80 assembly language
 * Operating system design
 * Classic UNIX
 * Computer history

This site is intentionally simple.
If the information is useful, that's what matters.
