I do have the equipment to shoot some but a lack of time atm. Give me a ping in two months, if you don‘t get some through other channels.
For what reasons do yo need the images?

I want to upgrade my Sakhar AX-370, and I wanna make sure that the circuit for the roms are ok to make it MSX2+ whether with the need of change the jumpers locations or not.

The PCB of the AX370 is a little bit different specially at the back. I want to see what is the best way to go with this project, I have few ideas in my head. I also wanna see if I can have both Sakhar MSX2 and Sanyo MSX2+ available with a toggling switch.

I am also interested in having a picture for the rapid fire circuit and all of its components.

The reason asking for that is that there is no service manual for all these Sanyo machines (70FD, AX370, etc..)

Not sure if these links could help you. In the second one, the images can be enlarged.

Thank you for sharing. I will try first to see if I can put the files on 27C020 chip and organize them in slots as seen by the AX370. If that work, that will be it. Otherwise I will have to look closely in the circuit and try to do something about it. I prefer the first option to work because It will not be difficult to do :D
