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? ******************************************************** Just for reference: Picture of the CPU http://rossiters.com/docs/tailgunner-cpu.jpg Tailgunner Schematics - http://rossiters.com/docs/tailgunner-CPU.pdf ************************************************************ Matt
