Hi,
I would like to build a programmer for uC HC908, but i couldn't find universal programmer. Of course I can buy it, but it cost too much for me. Could You tell me were can I find MON08 programmer, maybe something else.
Thank you for Your time.

There are many variants of the HC908 with different pinouts, packages. The circuit for each controller is in the datasheet chapter "Monitor ROM". You can easily build it, have a look at Page 1.7 :
On the PC you need the free software from P&E from their website.

You need to specify which HC08 variant. I use the QT4 and the JB8, and I just built the circuit in the datasheet for the QT4, and built a variant of the JB8 datasheet circuit (I used a Schottky diode instead of the chip linking the JB8 to the MAX232).
