Well I harvested a CPU from a Saturn and Im still getting a Bad Slave CPU. I tested all the traces under and around the CPU. No bridges or loose pins. It must be something else.. I went back and swapped the MAIN CPU and same result. Not sure where to go from this point.

I couldnt find any on eBay. The only option is Alibaba, Utsource or a Saturn.

That makes sense. I bought a couple broken Sega Saturns with the intent to harvest the CPUs . Ended up fixing both and couldn't bring myself to harvest parts on a working systems. I will have to find another to harvest. Thanks for the help

Ya those damn CPUS! Worst design ever. I have 2 working STV boards this is my 3rd. and Its a back burner project i finally got around to look at. it after two years. Might need to harvest a CPU from a junk Saturn.

I just found this somewhat hidden menu earlier and the dual CPU test and it says the salve CPU is bad. i tested all 144 pin and no bridges and everything seems connected. I went over it again. same bad slave message. These aren't the original CPUs. I bought them from UTsource couple years ago...

I cleaned the cartridge slot and reflowed the ram.

Thanks for the help. I'll get some replacements.

Anyone else have the issue where the ram test doesn't complete? I would expect it to complete the ram test showing all potential bad rams.

I did reflow. No bueno

I plan on replacing the bad ram(potentially). I'm about to burn the multi bios and test again. I don't expect and different results.

I've had the broken STV board for a couple years. It had some physical damage to the CPUs and couple resistor arrays and caps. I decided to work on it today. I replaced the CPUs, caps and arrays, The system boot with or without the the DS Multi cart.to an error message. . I then hit the service...

Add me to the list please

Hi, I'm just finishing up some 3D printed plates for the Sega C2 Multi. Just need to adjust the standoffs and mount for a Pi Zero W to use with BladeZx's awesome selector. Ill be posting the files soon. I also made some matching eprom labels. Heres a sneak peek. Please feel free to scrutinize...

You still have some Naomi 2 sticker left?

Will there be a seperate soundboard thall work with the older multi?

I was just showing the shell in red. Yes it fits. I had no issues. A friend of mine and I built some at the same time. We both socketed both side and used that 3D printed shell.

I was able to socket both sides if you use the 3D printed shell available.

I use these all the time to straighten pins. https://a.co/d/goFO1ZS

Can you please add me. Thanks
