Thought the Sega Bomber (

This machine really is something else....
First the monitor: I have never seen this one before. It is a Nec monitor in every way, the CRT is Nec as well as the chassis. The shape of the chassis would make you think it might be a TV chassis in essence....
The tube
Overview of the chassis. It is mounted sideways.
Separate controls but still need to adjust from the back....
Detail of the separate section on the left:
Overview if the lower section. On the bottom left three (!) transformers, HUGE heatsink, some diode bridge and a couple of big caps.
In the middle you see the two (!) PCBs with an interesting mounting method.
Top left you see the coin-mech with under it the bucket. To the right there is was looks like a sound amp and a board to adjust every individual sound.
Power supply section:
Audio amp (we think):
The individual sound pots PCB:
Coin section and joystick:
Control section:
As mentioned, there are TWO PCB's for a simple game like this.....why ? Well.....pretty simple: it doesn't have a processor. Like Pong and several other games of this era, but we were still a bit surprised by this....
Here is PCB 1:
Code of PCB1 (SEGA 95576X-P):
PCB2:
PCB2 code (SEGA 95575X-P)
As you can see no processor, only TTL chips and a couple of character ROMs. Totally amazing that this thing still works IMHO.
Also because it doesn't have a processor it is not in MAME.
The plan is to work a bit on it the friday evening before we go to the South Coast Slam. We'll clean it (further, Robin already did some cleaning)
We will give it a spin now that we can credit it, I'll see if I can put a (temporary) credit button on the front so it can be played on the Slam show and make some video and pics of it running ! Then we'll remove the joystick for the transport.
I would really like to know if someone knows which monitor that Nec is. There are some markings on the PCB but I don't believe it's the model nr.
