Is your chip SST39VF800 ?
What second adapter used (T07 or T08) ?
Chip is 16 bit, T10/T07 required.
Adapter settings as shown in picture 29Fx00 on adapter.
Chip is 3.3 V device, set programmer Vcc=5V and remove jumper (open 3.6V) on adapter T07 Quote:
the hy28f800bt-70how i use it
It is rare chip and datasheet not available. Chip has bottom boot (B) and tsop48 (T) package. Chip can be programmed on Willem , selected 28F800B5-B or LH28F800-B, tick option erase by memory map 8kB/block in SW. Note set Vpp=12.7V. Quote:

You can replace it with any 29F800T chip from different manufacturers.
