Probably an algorithm problem. Do you have the datasheet?

The problem may be related to the power too. Those old EPROMs may need very high current when programming. But programmer only can provide very limited current.

Here is the procedure I use, which seems to work for me:

1. Plugin the GQ-4x programmer into the USB port, and listen for double-beep
2. Plugin an external 9v power supply
3. Start the GQ USB Programmer Software
4. Set device to "TMS2532A(READ ONLY)"
Note: This will set the Vpp to 21v instead of 25v
Do not use 2532 devices (without the "A") at 25v as they will fry the chip forever
5. Set the Speed to lowest value (-2)
6. Select Write, Verify and Double-Write
7. Load your bin file
8. Click the Write button (it will write twice, and then verify)
