Hello everyone !!
I have a Top2005 programmer with no problem on eprom/eeprom or flash neither with sram or ic test but with pal gal or pld devices like you call this ones, i have encountered some problems.
In particular, when i select pld devices in the type menu, after done the operations the software don't exit, it return "access violation error".
Another thing that happen is that i have many GAL16V8 and GAL22V10 manufactured by National Semicond but my programmer do not erase/write or read it.
I have also many PALCE16V8 and PALCE22V10 but i'm not sure for the exact compatibility with GAL (also if on the datasheet they say is the same like GAL).
Why ZLM don't answer me ?????
I'm the only with this problem ?????
Pls someone who's answer at this question !!!!!

For the use of everyone :
i've found the right mode to handle GAL16V8 made by NS, you must to select Manufacturer VLSI type VP16V8,
ZLM or who's for you tell us why this happen !!!
By now no success with GAL22V10 or PALCE series.
Why when i select a device the programmer "feel" if they are in place or not, instead whe in select 22v10 it don't feel nothing ????????????
There is a technical support for this chinese product ??
