Does anyone have a legit real dump of the A-19993.u38 pal chip?

The one currently in mame is a dummy file as the pal2gal calculations are wrong and the fusemaps once turned into jed basically are redudant and point back to themselves. when burning to a new palchip it causes the machines to black screen of death.

It doesnt seem that there is a legit dump anywhere and finding these chips any more are close to impossible as they where only available in the link kits, or for operators that left them on the boards of the games they sold.. finding one anywhere has been non-existent.
