Philmur has sent me his Pacman diagnostic ROM.
Pacman test ROM – philmurr 05/20
Fits at location 6E
Tests programme, colour, video and sprite RAM 1 (note sprite RAM 2 is write-only)
Displays sprites dropping from screen to show sprite select and addressing is working (tries to show all 8 but most boards only have 6)
Shows real-time status of inputs and DIPs
Colour RAM – 4P, 4L
Prog RAM – 4R, 4M
Video RAM – 4N, 4K
Sprite RAM 1 – part of 4R,4M but may make it clearer to people when testing
File can be downloaded in the “Downloads/ROM files/Diagnostic” menu
Thanks to Philmur for his hard work and for sharing this
