This article relates generally to personal computer programming and, more particularly, to apparatus for altering a variety of electrically programmable read-only memories (EPROMs). The addition of an adapter and circuit card externally of a personal computer enables more convenient verification and alteration of EPROMs, and adaptation to different techniques. Referring to the figure, data and control lines are brought via cable connector 1 to an EPROM socket 2 at the rear of a personal computer. An EPROM can thus be mounted on the personal computer without the need of cover removal. In operation, proper line connections are insured by transmitting a wrap bit from internal register 3 to register 4 along a path including opposite ends of connector 1.
