27512 J-2 chip manufacturer EPROM questions operation wolf
I am having difficulty checking and programming some EPROMS. I have 7 questions about programming this chip using Needhams EMP-11. If you can answer any or all please help.
1. Who is the manufacturer of this chip?
2. Can I use any Manufacturer from the list on the programming software to program this 27512 device.
3. I have tried just about every Manufacturer and 27512 that I can find in the device selection list and every time I do a checksum...I get "00FF000" (I have tried two different 27512's pulled from my op wolf main board.) Something seems fishy about this to me. What's up with that?
4. I peeled back the tape and I assume that these are UVEPROMs. Is this correct?
5. Can I use flouresent light or set them out in the sun for an extended period of time to erase them?
6. Should they be erased and preform a "blank check" on them before programming them?
7. After erasing one will the checksum value read "00000000" ?
Any help would be greatly appreciated.
