EPROMs are erased by exposing them to ultraviolet light, EEPROMs are erased electrically. I know of no EEPROM programmers made specifically for the Apple, but I should think some of the units available that connect to a serial port would work nicely. However, to program 2716 and 2764 EPROMs (the ultraviolet kind), try Needham's Electronics at 4535 Orange Grove Ave., Sacramento, CA, 95841, (916) 924-8037 fax (916) 972-9960. I bought a unit that plugs into one of the Apple's expansion slots and programs 2716 (single +5v supply only, not the older 3 supply devices), 2732, 2764, 27128, 27256, and 27512 chips, and one or two others, for $109.00 at a local retailer. >I am interested in either a commercial product or a kit or magazine article >describing how to build one.
