Quantity   Component name
1 × 68B09 CPU A Motorola or second source compatible 6809 CPU (this is not to be confused with the 6809E or EP )
4 × SIP-9 (BUS Type) 10k Resistor networks these tie each 10k path through pin 1
5 × 10k Resistor 5% or better 1/4 or 1/2 Watt Footprint uses 1/2 watt but they are not required
4 × 1k Resistor 5% or better, 1 is for optional power module mod, 2 for the optional serial card and may be omitted (1/2 or 1/4 Watt)
1 × SN74HCT00N Logic ICs / Gates and Inverters
1 × SN74HCT138N Logic ICs / Decoders, Encoders, Multiplexers, Demultiplexers
1 × Tactile Push button A 6x6 will fit, but you may have to splay the legs out a bit.
1 × Latching DPDT switch a 7x7 will fit, but you may have to splay the legs out a bit.
1 × DC005 5.5x2.1mm Barrel Jack Standard layout barrel jack, whatever fits your supply
1 × LED 5mm The Drop resistor is 1K which may need to be ajusted depending on your part but should be good enough for most standard 5mm leds
6 × Sockets Various sizes -- The EPROM Silkscreen and bypass cap are positioned for even a large ZIF socket if desired
1 × Buck Converter Module LM2596 DC to DC Converter module, optional if you intend to build your own power supply.
4 × 2.54mm 2x20 40-Pin Female Pin Header Expansion slot connector
1 × 2.54mm 2x20 40-Pin Male Right Angle Header For the Serial expansion card (if desired)
1 × 68B50 (6850 ACIA) Sierial Chip (highest speed grade) For the Serial Expansion card (if desired)
6 × 100pF bypass capacitors Regular Ceramic Disk is fine
1 × 4.7 uF Capacitor I used an electrolytic, a tantalum or ceramic would be better.
8 × 47 uF Electrolytic capacitors These are source caps for the card edge connectors. 10 or 25v fit well in this footprint.
1 × 1N4148 Diode Silicon Switching diode
1 × HB6809 PCB Main PCB
1 × HB6809 Minimal ACIA Serial Module PCB optional, but required for serial output and highly recommended
1 × 62256 compatible SRAM
1 × 27128 compatible EEPROM / EPROM You can use my instructions found on the Hack a day Page to use a compatible 32k ROM as well.
1 × 7.3728 Mhz Crystal
2 × 22pf Ceramic disk capacitors
1 × 8 position dip switch ACIA Adapter needs a dip switch block for picking which interrupt line to route the signal down.
