Hi, I´m trying to build a PS1 repro from an Afterburner pcb from tectoy (need to add sram chip,watchdog battery circuit, connection pads in the edge, etc). front back Here in reddit, some people builded themselves one, but i have one problem, all the datasheet I come across of ST 27c4001 have pin 22 & pin 24 swapped compared to the tutorial here. In the tut, they are: Pin 22= GND pin 24=CE If I folow these instructions, but guided by datasheet, I will ground CE on the EPROM and ground CE on the 315-5235 So, connect the by tut or by datasheet? submitted by /u/Crissaegrim87 [link] [comments] |
