I’ve been given a Jackrabbit development board Z-World, Inc from I’m guessing 2000, 2001 and tasked with buying more or getting current equivalents.
It is made up of two boards. The bottom board has 9 red leds, 5 momentary switches. It has 2 - 40 pin, 2mm pitch connectors interfacing with the daughter card, and 2 - 40 pin, .1" pitch connectors on the bottom of the board. Also has a 10 pin header for serial connection on the corner of the board.
The daughtercard has a battery installed and a Silicon Storage Technology 29EE010 1Mbit EEPROM.
