Commodore 64 Unblinker
This program will remove the blink from the cursor on the Commodore 64 without affecting anything else. The program is a BASIC loader for an interrupt-driven machine language program. It will remove itself from memory when you run it, so be sure to save it first.

    Hitting RUN/STOP-RESTORE will enable the normal cursor blink. SYS 688 will restore the Unblink routine.
Thank you for the contribution.
