I have a GQ-4X True USB Universal Programmer question.
I have a 8051 adapter.

A new circuit is Philips NXP P87C51SBPN PPV programming voltage 12.75V

A new program is updated, with Philips added

A device ID check tells that Intel 8751 circuit is 8951 circuit, type unknown.
Should I leave ID check off?

Writing do not success to NXP P87C51SBPN circuit, it starts, but stops after 1000 addresses.

Regards
Pekka Ritamaki

If ID is incorrect you probably have a fake chip.

You should be using ADP-015 https://www.mcumall.com/store/index.php?route=product/product&path=62&product_id=58 because other adapters might not work.
