 |
|
I built a SI-PROG interface, following Victor’s guide (http://www.allservice.ro/forum/viewtopic.php?t=47), and after several “ERROR: Circuit not found or bus error!” the T-30 appears to be dead. I followed all the suggestions in the step 4 of this guide but it seems I’m doing something wrong. Is there any way to bring the T-30 back to life? What did I do wrong in the interface? Did I killed the eeprom? I’ll appreciate all the help you guys can give me.
These are the pictures of the interface I bult:
Thanks in advance |

The resistors color code must be :red, red ,red =2200 Ohms. Check to be sure.
The picture is not well focused and I can't see exactly what is the diode polarity. Beware, the diodes must be 5.1 zeners. |
