I had a huge gap, between playing with the Spectrum in the early eighties to using a PC for the first time around 1992. I remember using QBasic, and using debug.com to write simple assembly programs - the most memorable one was a simple utility to "undelete" files from MS-DOS, which just involved modifying the FAT. Most of my memories of the early PC-days were reading Ralph Brown's interrupt list and looking at the source code of viruses, via magazines such as 40HEX.
