ProtoBoard III
The ProtoBoard III is an 160x100mm EBC bus prototyping board that feature a generous through hole prototyping area and the typical bus buffering and address decoding required to implement an I/O peripheral.
Features:
- Flexible 6-bit I/O address range selection
- Pin headers for buffered address, data and control signals.
- ECB bus pinout area for access to other ECB signals.
<font 16px/inherit;;inherit;;inherit>The board may be constructed with either the 74LS682 (preferred), 74LS684, or 74LS688 chip. The last two require a strip of 22K bussed resistors; the first does not.</font>
<font 16px/inherit;;inherit;;inherit>Note that the footprint for the second ECB connector is for access to ECB signal lines and is not suitable for connect to another ECB board through a female vertical connector.</font>
