The EMIT e-card is used for orienteering races, to register control codes and split times. When punching, the e-card registers the unit's code and running time. The e-card can store up to 50 split times. The split times are stored internal in the e-card until restarted on a starting unit.
The ecard is used with a control unit like this:
The ecard uses a 2032 battery, and here is some of the components:
- Texas Instruments HC368 (bottom right of circuit board)
- 24C02M, which is an E2PROM (bottom left of curcuit board). Couldn't find the exact component, but you can see many similar here: https://www.qdatasheet.com/search.jsp?sWord=24C02M&op=i
- MC705J1ACDWE, a microcontroller (in the middle)
- CD4060BCM 14-Stage Ripple Carry Binary Counters
- 32.768 kHz oscillator
Unindentified components:
- White component to the left of microcontroller.
