Neck-deep in computers since my first Apple II+, I've done just about everything in this field.
Currently I'm having fun setting up and running various kinds of servers, and developing web sites both professionally and for kicks.
I recently provided Apple II floppy disk conversion services to a college in the US (pro bono).
I run a modded-but-no-downloads-required co-operative Battlefield 1942 server called Tanks 'n Planes Unlimited, which you can find via http://jdrgaming.com.
I also have a computing blog: http://boot13.com.
My consulting business: http://jrc-core.com.
