===== Build procedure for Tiny68K bare pc board =====

**Note: This page is for reference. This is not the build instruction for Tiny68k kits that were shipped. Refer to [[boards:sbc:tiny68k:tiny68k_kit2|kit 2 instruction]].**

Solder the Altera EPM7128 with a fine-tip. Match pin 1 of EPM7128 (marked with a dimple) with silkscreened pin 1.

Resistors R3-R9 (220 ohm), R14 (2.7K), R13 (4.7K), R16-18 (4.7K), and R10 (10K).

Do not populate R11 and R15

SMT filter capacitors C9-C12, C10-C12 are located at the solder side of the pc board

SMT resistor R12 (27K) located at the solder side of the pc board

SMT capacitors C2-3 (20pF) located at the solder side of the pc board

Bypass capacitors

3.6864MHz crystal

DIP8 sockets for U5 and U7

4-pin socket for the 8-16MHz oscillator, the socket can be built out of individual machined socket pins and hold in proper alignment with a 14-pin socket

Solder two terminals of T1 with a jumper wire

SIP resistors R1-2 (4.7K)

7-segment LED display, the decimal point is nearest to the pcb corner

push button for reset

MCP130 voltage supervisor

2×5 header for Altera programming header

2.5mm power jack

Connect USB blaster to Altera programming header, apply 5V via the 2.5mm power jack (center is +5V, barrel is ground), program & verify the CPLD

Install 2-terminal headers at T18/19, T20/21

Install 68000

Install 68681

SIMM72 socket

6-pin header for the console serial port

Program a 24C256 with boot software, install the 24C256 in U5 and install a shorting block between T18/19

Install 44-pin IDE-CF module, keep the module at the same level (another word, in the same plane) as the board before soldering

Power up!
