I'm still stuck on this issue with my tailgunner board.  Right now it's working 100%.  But one of the roms is showing signs of being flakey after it warms up after 10 minutes.

All I want to do is replace the two roms  http://rossiters.com/docs/tailgunner-proms.jpg - with some freshly burned eproms.
I think these are masked roms.  

If you look at this page http://rossiters.com/docs/rom-pinouts.html - it looks like the pinouts of these roms are similar to the TMS2532 roms.

I'm not sure what I'm doing wrong.  Maybe I'm not putting the right data on these roms.  I know how to take the 4 2716 roms and combine them into 2 roms.  I'm
Just not sure what order they go.

Could someone please offer some suggestions?
