Back in the early 1990s I was in college and working in the computer lab. So I wrote various little DOS utilities to help us better manage the computers and the interaction with Novell Netware.
Due to this reminiscing I have even purchased a few tech books from that time. MS-DOS Encyclopedia, Peter Norton's Programmers Guide to the IBM PC, and some others.
I only wish I still had a copy of SpontaneousAssembly 3.0 as it would be fun to recompile some of my old code!
