Verbum is a program to punch human-readable text on paper tape, for use as a leader before a program. It was written for the PDP-1 Restoration Project. The 64-character subset of ASCII printable characters (codes 20 through 5F hexadecimal) are available as a 5x7 font. Only the least significant seven channels of eight-level tape are used, with the most significant channel always zero (no holes), so that the readin mode of the PDP-1 will ignore the text.

Verbum is written in C and should be fairly portable.
