Hi. Hardware questions:
When I remove the ROM board on my machine, I find unused pads in the back of the board. I beleive that that is the case with al ROM boards. Anyone correct me if I am wrong.
I also know that the Flash RAM can be extended by another 8MB through a card in the ROM slot. I also hear that is has been done, but I don;t know who did it or when.
So here are my questions:
Is my assumption correct that those four free spaces in the back of my ROM card exist on all ROM cards?
If that is so, are they meant to take Flash RAM chips?
If they are, the documentation requires 28f016sa-compatible chips, but they use TSOP 56 cases. There are similar parts that have TSOP 48 cases that would fit, for example the 28f160 - maybe 28f016 vs. 28f160 is just a type. Could that be the case?
If all that is true, then I still find a few extra pads, probably needing resistors and caps. Does anyone know what values these need to be?
Any help is greatly appreciated. Think 12MB Flash ;-)
