Abstract
The apparatus includes a socket (13) for receiving an EPROM (18) to be programmed, a telephone interface (11), an RS-232 port (14), and RAM storage 20. Each of the user elements can be a source or destination of data. A microprocessor (52), and an internal EPROM (54) which includes firmware for programming EPROM (18) control the operation of the apparatus, providing the operator a series of prompts through display 15 to which the operator responds through the operation of "yes", "no" and "cancel" buttons.
Claims15
A portable apparatus for programming EPROM devices and the like with selected EPROM program information, comprising:
- means for selectively receiving and releasing an EPROM device to be programmed;
- means for accepting EPROM program information from, and for transmitting EPROM program information to, a remote source over telephone lines;
- means for accepting EPROM program information from, and for transmitting EPROM program information to, a local computer means or the like, including another said EPROM programming apparatus, wherein said computer means is separate from said EPROM programming apparatus;
- means for storing EPROM program information;
- means for communicating between said remote source information accepting/transmitting means, said computer means information accepting/transmitting means, and the EPROM program information storing means;
- means for programming a variety of EPROM devices with selected EPROM program information, wherein said EPROM programming apparatus is characterized by being arranged such that it can be conveniently carried to the site of the EPROM to be programmed;
- and
- means for verifying the accuracy of EPROM program information already present in the EPROM device to be programmed and for identifying any differences between said EPROM information already present in the EPROM and said selected EPROM program information.
