LPTstat shows each bit's status in real-time, and includes the bit's location in the PC address space and its corresponding pin number on a DB-25 connector. You can use the left and right arrow keys to switch LPT ports, and the up and down arrow keys followed by ENTER to toggle a bit.

XCODE v1.0 (XCODE)
XCODE protects a file with a password by performing a mathematical calculation on each byte. The coding is bidirectional because the same process is used in encoding as decoding. Type XCODE filename and then type in a password to encode the file, then type XCODE filename and supply the password to decode. Also see the Windows version of this utility.

Directory to Web v1.41 (DIR2WEB.EXE)
Reads a user-defined filespec (e.g. *.*) and creates an HTML index file.

If files are numbered starting at a number other than 0, try re-running the program.
