Disklook

Summary

DISKLOOK is a utility program designed for a PDP-8 computer equipped with a 32-K DF32 disk drive. It allows users to interactively examine and modify disk contents using a Teletype terminal.

Key features include:

• Examination and Alteration: Users can view or change the octal contents of specific disk addresses. A special "x.y" address format is supported to simplify accessing specific words within blocks.
• Searches: The program supports both positive and negative masked searches across a user-defined range of disk addresses. Due to the lack of data buffering, searches are relatively slow.
• Control Functions: Users can terminate searches immediately by pressing any key. A command is provided to return to the resident monitor.
• Error Handling: The program provides feedback for illegal user input ("?") and disk-related errors ("DE").
• Technical Details: The program runs in memory locations 200 through 777.
