attiny85 programmer
Hi there, im new to microcontrollers and want to make my own programmer to simply read data from ATTINY85 chips (writting data will come later).
I have tried building LOADS of different serial and parralel programmers but no software reads or identifies the chip.
I have read lods of websites and documents and thought it was about time i asked for help.
Can anyone tell me of a parralel or serial programmer that I can build that will allow me to read the ATTINY85? Also can you post any diagrams or schematics? I have been using schematics that show everything from the pc port to the ISP header, I never know what to do after that - i just connect each ISP pin to the pins on the ATTINY 85 - ISP MOSI goes to IC MOSI, ISP SCK goes to IC SCK ect.
Since I only need to read at the moment, can someone advise me if I really need an ISP header?
As I said I'm a noob and my first goal is to get the PC to at least see the IC before I attempt to read/write.
Many thanks.

PS. the ATTINY85 I have has already been programmed by someone else and had the programs configuration settings saved to it too so data is there to be read. And the IC aint broke as far as I know as it works in the target board still.
