1Building Instruction for Stage 3 of Tiny030
There are lots of manual wires in Stage 2. It is meant to help me designing a revised Tiny030 board. If you are working with rev 0 pc board, you may want to do Stage 1 to check out CPLD functionalities, skip over Stage 2 and follow this Stage 3 Instruction. Or if you are confident about the CPLD, you can start with this instruction and skips over stage 1 and stage 2. Tiny030 pc board needs minor engineering change just for stage 3. 3 extra resistors are needed and 3 extra wires are needed. The three pictures below show the component side of Tiny030 at stage 3, solder side, and lastly populated board.

Picture below shows the location of two 22pF capacitors. I do not have the leaded capacitors, so I substitute two SMT 22pF capacitors on the solder side of the pc board.![]()

The CPLD equations, ROM monitor, EhBASIC, and memory diagnostic described in stage 3 projects all work with this board.
