About the Fennec6800 PCB
Fennec6800 is an open source PCB design by ChartreuseK, published on GitHub under the BSD-3-Clause license. It is a 2-layer board measuring 218 × 131.9 mm, with 113 components from 37 distinct parts.
Other key parts include the 74LS00, 74LS04, 74LS193, 74LS73 and 74LS02. By type, the board carries 54 capacitors, 37 ICs, 12 resistors, 4 switches, 2 connectors and 1 transistor.
From the project
Fennec 6800 Homebrew Single Board Computer
The Fennec 6800 includes a capable and expandable ROM monitor built in, requiring no tedious toggling of front panel switches to enter and begin executing code. Only a terminal is required to begin making use of the system, simply hook the terminal up to the bottom serial port (furthest from the power jack). This serial port is the local console port in the default system, all traffic is normally routed through this port, though inside the monitor certain commands may be redirected to the auxiliary port located above it.
