Notes
This card exists in two versions - a slower one (ProNitron GA) that clocks the video processor at 35MHz and a faster one (ProNitron GA+) that's running at 44MHz. GAL/PAL code seems to be identical between both versions but speed ratings differ. For GAL #1 the actual content did differ between two of my cards. They both seem to be interchangeable. All GALs/PALs on the 35MHz card are 15ns. The 44MHz card differs in that it has 7ns parts in place for PAL3, PAL4 and 10ns for PAL 5 and 6.
