6351 PROM burner

[Georgian2]

Hello,

Dose anybody know what programmer can burn this kind of non standard pinout proms?
Here is the pinout: https://archive.org/details/6309PROM/page/n3/mode/2up

I did try to make an adapter for it like the 6353 but the E2 is active high on the 6351. I did try to negate it with an LS04 (powerd externaly with common ground) but my labtool-48 still dosen't like it.

Thanks.

Looks like these are a nightmare that almost nothing supports, even my old stag programmer goes from 6349 to 6352/3.

There's an old thread here https://www.vectorlist.org/TechTools/2006/05/0015.html

Your best bet might be these guys https://arcadechips.com/product_info.php?products_id=187&osCsid=o7ubb43jhhcmt4cg7tuioeg2h6

Unless there's an equivalent prom that has better support.

I did find this webpage too. I'm looking for a way to burn them myself. I have like 20 of them. As far as I can find, they are most common used on gottlieb system 1 pinball with both enable pins on gnd and vcc. This way, they can easly be replaced with an "modern" one and an adapter. Maybe there isn't any demand for it after all... Still it would be nice to be able to burn them.
