Hi people,
Perhaps someone can help me out with this one.
I'm having difficulty with properly reading and writing this chip, as it's not listed in the supported list.
It's a 14 pin National Semiconductor SOIC 93C56EM chip.
Can someone give me a hint, or even better, add support for this type of chip into the program ?
Thanks very much !!
Pvl |

Thanks for your efford to help me out.
I've successfully programmed this chip with my old original willem V3 programmer using IC-prog from bonny gyssen. As
the willem software has a bug to do this correctly.
Now onto the main problem. Afterwards programming it, i tried to read it out with the GQ-4X. And it crashed halfway reading.
I selected a 93c56A as this chip is a 256byte (1K) version. Thus therefore i'm still wondering what can be wrong. And i would
like to see some proper selectable type in the main software. This would greatly simplify the search&select of the right chip
to begin with.
The chip is mounted on a printplate of a tacho (dashclock) and i had to jumper the quartz to properly program it with the willem.
The dashclock works again, and this means the willem was able to do the task properly. Now my freshly bought GQ-4x is the one
to get going. I have a second dashclock which also has a erased chip in it, and needs reprogramming (same chipcode) and more
detailed info is coming soon. I'll try multiple possibilities. Plus an external powersupply connected to it.
If anyone has hints or tips, please state them.
Thanks |

| If you program it in-circuit, do not connect the VCC pin, power up your chip target board. |
