I have been trying to burn a few PROMS lately and have had zero luck burning the NTE chips I have bought. I have tried and NTE74S751 (crosses with 82S131) and NTE74S387 (crosses with 82S126)

I bought the chips new off the shelf at Norvac. I have tried 4 burners, a data io unisite, a Xeltek SuperPro, a BPM-Microsystems 1410 and a data io chipmax. ALL of them list 74s751 and 74s387 but all of them fail to burn these chips.

The question is, has anyone had any success with these NTE chips? I find it hard to believe that 4 different programmers are all broken.

I haven't tried those 7400 series chips on my TopMax. It has NO problems programming 82S series PROMs or PLA chips.

Try using settings for the signetic part equivelant. I havent come across a prom that the data IO Unipak 2B wouldnt burn. I dont mess with NTE parts though.
Did you verify they are blank?

They do verify blank on every unit just wont write. I like the idea of the NTE parts because I can get them locally but if they just dont work I'd like to stop wasting money on them.

What are NTE proms ?

I've never heard of them,
and none of my (6) programmers even has them as supported devices ... ?

Just curious...

NTE Electronics, Inc.

They sell all kinds of electronics including PROMS that are supposed to match the specs of the referenced chip.

Here is what NTE support person had to say...

ME: "I am trying to program an NTE74S571 to replace an older bi polar rom 82s131. They appear to be read compatable but not program compatable so I need a data sheet so I can get the right algorithm to program the device. Where would I find the data sheet for this, can you email it to me?

Thank you
-Ken"

NTE Support: " Hello, "74S571" is a industry standard part number you may go off any other companies datasheet for this part. I do know that National Semiconductor has one you may find online, but I'm sure their could be other companies.
Regards,
Rich"

I know a lot of times.......NTE just buys surplus of other companies stuff, and stamps their NTE name over the other companies logo. Many times I've seen the Texas Instruments logo showing through the NTE name. Can you see any other name showing through the NTE name?

I would guess that most of their parts are just rebranded parts with inflated prices to go with it. Maybe thats where the Chinese learned how to sand and restamp chips :)
 
I have a BK866 we could try. Although I know some chips require a bit more current to program than others. Do you get a warning before you try to program those? LMK

It does not look like its been rebranded but who knows.
