I have two issues:
1 - How do I get it out of "demo mode"
2 - Should it have an ac adapter plug? I use the USB cord and I assume it is getting power because the green G/E light is illuminated.
I need to substitute an AMD PAL16R6 -20pin
The VP 890 is ok for it? or do I need to buy an another programmer?
..or an adapter?
Let me know
I have a VP-996 programmer and I am trying record an AT89S2051 soic, if I use an adapter with paralel mode it works, but if I try with adapter ISP with the cable It works ( read, prog config, compare) but doesn´t erase and doesn´t program, when I interchange MOSI per MISO, Erase It works, only program doesn´t works, I upgrade my version today 4.6.5,the message it´s:

Double click on wellon icon - programm running, but say "Programmer initiate failure! - The system is in demo mode!" If i disconnect programmer and run programm without, i can select manually programmer and programm allow me make update. During update, leds is blinking. Programm shows "update ok" but no change on programmer work.

I have problem with reading AM29LV017D memories. When I place memory in adapter and start reading, programmer indicates problem with memory connections (few pins blink): http://www.wrkom.pl/am29lv017d.jpg I was trying to clean pins of memory but it doesn`t matter, all connections are good. My memory is in standard TSOP40 package and I am using pin to pin TSOP adapter. Ofcourse adapter works fine with other types of memories, problem is only with AM29LV017D. Can you help me?
I try to read a hex file to buffer but the buffer is empty. From user manual, it should have a dialogue window open but it have not. 選中檔後，將會彈出一個對話方塊（見5.1.1），點擊“確定”完成檔的讀入。I also try to read 89c52 to buffer, it is the same. At last, I remove the software and reinstall. It is no difference at all. Have any setting I have missing. Please advice
