Hey all. I picked up a weird F14 Tomcat today. I’ve had one other one and it was my understanding that these used the #555 light boards underneath the playfield in several locations. This one is 100% individual #47 lamps underneath every insert.
Also, the row of flasher domes on the back are clear on this one when they are usually red. Finally, the game plays pretty well but the MPU lights never come on. When I test diagnostic button on the MPU it says Mem.Protect Fail.
Here are a couple photos of the serial. The date of manufacture is either worn off or blank. Any thoughts on this machine? Is it really a prototype or just a really early production? Thank you!
