Hi,
I have been trying to burn different bios for Dreamcast onto the required EEPROM without success.
Using TOP3100 with adapter SOP44 to DIP44.
The chip can be erased, read, blank, write but I get the same error over and over again upon "verify" process.
"error at:0001: (FF)"
So I decided to write w/o verifying but the chip remains blank / no data.
I have also noticed that the voltage is constant 3v against regular EPROM at 5v.
Any ideas on why the EEPROM doesn't retain any data after writing?
Is it necessary or even possible to adjust the voltage on the programmer?
Thanks
