Assembly
The 8085 SBC rev 3 is designed to be easy to assemble for anyone with moderate soldering ability.
It is a moderately complex board and will typically require between one and three hours of assembly
time, depending on the skill of the assembler. The following tools will be required:
•
Soldering iron, 20-40 W recommended, grounded tip
•
Solder, 63/37 leaded solder recommended, Kester “44 Core” or similar
•
Diagonal cutters or flush cutters
•
Solder braid, solder sucker, or desoldering station, in the event errors are made
•
Needle-nose pilers for bending component leads
•
1/4 and 1/8 W resistor lead forms (optional)
This manual does not cover basic soldering technique. If you are new to soldering, we recommend the
Adafruit soldering guide and plenty of practice on a piece of protoboard, before beginning assembly
of the 8085 SBC rev 3. The Adafruit guide can be found at:

3.1
Assembling the 8085 SBC rev 3
If you purchased a full Glitch Works parts kit, we recommend completing all assembly sections, since
extra features can be disabled as needed. If supplying your own parts, you may choose which sections
to complete based on the functionality required.
Note that pin 1 is designated with a square pad for all ICs, resistor packs, switches, and most
connectors. Pin 1 is toward the top of the board, as seen from the front, for all ICs, diodes, resistor
packs, and switches. The component (front) side of the board is the side which contains the white
silkscreen legend. It is recommended to install components from shortest to tallest, which makes
assembly without an assembly vise or jig easier, assuming the board is flipped over and soldered with
the component side resting on a table top.
All jumper headers and connector headers are press-fit and may require a bit of force or gentle
wiggling to install. This is normal and helps keep the headers in place when the board is flipped over
for soldering.
