Do you want to make the printed circuit boards of this project?
They are all single sided!!

Below the hyperlinks to get the PCB's

Instead of printing directly to a HP Laserjet,
I have printed to a file. These files got big so I compressed them with WINZIP.

You have to unzip them and in a DOS-box, with a
COPY 80C535.PRN LPT1
send them to a HP Laserjet-compatible printer

The making of Project.515/535.....

Etching the 535_I2C-mainboard

After drilling the 535_I2C-mainboard

Single sided boards, so some wires on the componentside

Some details...

Connectors and sockets....

Resistor-array, elco's, led....

Battery and resistors....

more details....

A complete 535_I2C-mainboard

next, the LCD-display...

some spacers and connectors.....

the cable for LCD and keyboard....

A complete 535_I2C-board with LCD-display and a backplane.

Have fun!!!!
