Hello , does anybody know if it is posible for me to program SST39VF800 Tsop48 chip? I have old Willem 3.1 Programmer with 8/16Bit adaptor and PCB45 Willem with Sivava T1 T7 T8 adaptors. I manage to program a lot of chips but 39VF800 and its cousin 39VF160 cannot be programmed. Any help appreciated thanks..

16bit adapter and 3.3V voltage required. Apply PCB4.5 and adapters T1/T7. Remove jumper "Open 3.6" on programmer.

Thanks EZO for your support but I am still not getting an ID, chip legs are clean, Setup as you instructed: PCB45 with T1 and T7 3.6V Jumper Open on proggy, configured the jumpers to 29Fx00 and left open the 3.6V jumper on the T7. I am using 0.98D5 software.

Here are 2 voltage jumpers , one on programmer, one on T7. Only one jumper should be applied, one removed.
Check jumper left from dipswitch panel, position Vpp (downside pins closed)

For SST39VF160 external adress cable required between T7 and programmer.
