Dear fellow enthusiasts,

I have finally started to resurrect my SEGA Monaco GP (the "Pro"
version), which has been stored away for many years. First problem
seems to be that the video board does not produce a proper video sync
signal. I have swapped that board with a spare one I have, resulting
in a proper picture on the monitor, however - as this swap board is in
rather bad shape otherwise - I'd still like to repair the original
one.

Tracing back to the pcb components from the sync output, I've come
across this part ( http://www.kersch.at/monaco_gp_5618.jpg ), labeled
"IAM 5618", with 9 pins and one of them being broken. As I have had no
success looking for data sheets: does anyone know what this is,
ideally with pinout and/or available replacement?

Thanks for your help!

I think that is a resistor pack, just measure one of the end legs to the ones in the middle and you will find your resistance in ohms. I have a set of boards in my shed just collecting dust(not literally) and if you need any parts or boards, let me know, will let go cheap plus shipping of course. I don't know if they work or not, but good for part salvage.
 
Yes, that did it. Replaced it with a row of 560 ohm resistors, thanks again for your help!

As I am struggling with a row of other problems with my Monaco GP: anyone here offering repair services for these old SEGA boards?

Thanks,
Martin
