+Ksarul Posted June 15, 2014 Share Posted June 15, 2014 After a long phone conversation with Arcadeshopper this weekend, an idea that we batted back and forth for a while germinated and took form. His problem was that though it is easy to make a four bank supercart from a TI cartridge board, it has a lot of wires and leaves a lot of room for error. I do layouts--so that problem is one that I can help solve. I'm about 90% finished with a purpose-built design for a four bank Supercart, which should make it easy for those who want to tinker with these a snap. I'll probably have to wait until the end of the summer to do a run of them, but I wanted to give folks a heads-up now. I attached an XPS file that shows the current state of the board design. . .

Stuart Posted June 16, 2014 Share Posted June 16, 2014 If you're laying out a new board, might want to look at using a Dallas DS1210 (8-pin DIL) to control the RAM power and /CE. Less likely to get RAM corruption if it is accessed while power is dying when you switch off. Stuart. 1 Quote Link to comment Share on other sites More sharing options...
+Ksarul Posted June 16, 2014 Author Share Posted June 16, 2014 I like that, Stuart. I will look at it to see where I can fit it in, as it looks like a more elegant solution than the diode/resistor matrix being used in the original design.
