The emulator has an IEEE-488 device at address 8. It can be used load and save (.prg) files.

EQUIP is a database program intended for tracking equipment purchases. Like most of Fisher's utility programs, this one is competent but not flashy. There's no input validation—the data fields are all free-form text (string) fields—so you can adapt this program to do whatever you want. There are functions to sort data, and to store and retrieve files from tape or disk. While there's nothing especially wrong with this program, I don't think many modern users are going to find much of interest here.
