Sorry if I'm posting in the incorrect place. I'm new and trying to figure this forum and the ways things are done here.

In there it states this: - There is unknown device (Sony CXK5808-55) on the board.

I've been searching for info on this IC and have found it in the Ghosts n Goblins schematic.

It is a 1k x 8 RAM (I'm not 100% sure if it's considered bipolar or static...) in a 22 pin package. It's not in ChipDir or out on any of the datasheet sites I've found yet. Sony has no old datasheets on it either.

Code:


The pinout is this:

A6 - 1     22 - Vcc
A5 - 2     21 - A7
A4 - 3     20 - A8
A3 - 4     19 - A9
A2 - 5     18 - /CE
A1 - 6     17 - /WE
A0 - 7     16 - D7
D0 - 8     15 - D6
D1 - 9     14 - D5
D2 - 10    13 - D4
Gnd- 11    12 - D3

It's funny... Capcom used only 256 x 8 in that chip. The upper 2 address lines are grounded.
