I'm in a try to save my sega/gremlin Carnival PCB.
First i had a ram issue and I follow "RAM was a MK4015/MK4027 a 4116 should have worked.. it did not. ordered NOS MK4027s"
So I ordered a MK4027 to replace one of the MK4015 with broken legs. The problem is that it become very hot.
SInce the screen is totally green, i have no more the yellow square indicating the ram problem. I hope i wouls save it.
The question : could i mix 4015 and 4027 ram or I have to find a 4015 ?
