The 2801Prog is a compact, low-cost programmer for the Motorola MCM2801P (2801) EEPROM. The 2801 is a first-generation EEPROM requiring a high voltage (+25V) for programming and thus is not supported by commercial 'universal' programmers. However, it was widely used in its day and thus a reliable method of reading and programming it is required for the maintenance of legacy equipment. For example, the 2801 is used to store the model differentiation and calibration data for the Mettler PE series of balances that are still widely used in laboratories around the world. As these chips age, the stored data is eventually lost and without it the scale will only display 'ERROR'. While the data itself is widely available (see here for example) before the 2801Prog no commercial programmer supported the 2801 EEPROM and thus there was no easy way of fixing the balances. However, with the 2801Prog it is a simple matter of point-and-click. This programmer connects to any computer with a 9600 baud RS-232 port and a terminal emulator and allows reading, verifying, and programming of the 2801 EEPROM. Also, gEEProg, a Python application for Macintosh, Windows, and Linux is available which allows access to all programmer functions via a GUI. The gEEProg application is available for download farther down this page. Included: 1x 2801Prog Rev. 1 EEPROM Programmer 1x Power Adapter 1x DB-9 RS-232 Cable Note: Hard copies of the manual and software are not included – they can be downloaded at the links below Download the 2801Prog Rev. 1 manual here Download gEEProg and the gEEProg manual here Download the MCM2801 datasheet here Note 2: After selling out of the original, Rev. 0, version of the 2801Prog, I have updated the board, ROM, and GUI application and am now selling a new Rev. 1 version. This new version features a ZIF socket on the side of the board instead of the middle which makes actuating the release lever much easier. It also fixes several small hardware and software bugs. The original Rev. 0 is obsolete and no longer available for sale, but its documentation, photos, and build files are preserved here for those who want them. Note also that the new gEEProg application replaces the 2801Prog GUI application that shipped with the Rev. 0 2801Prog. gEEprog works with all versions of the 2801Prog as well as all other D’Asaro Designs Programmers.
