Introduction
From time to time I'll tinker
with my collection, get new gear or simply have random thoughts
about vintage computing. I've been doing this for years but apart
from the odd note in discussion forums I've kept these things in
my head.
However, I've decided (for better
or worst) to jot a few of these
things down as they happen. Perhaps someone might find them useful?
The list below shows the entries
to date. I've grouped them under rough categories, with the latest post at the top. If interested in following
these activites, subscribe to this RSS feed.
Enjoy!
