Hi to All
Hope here can help me, i have two of the same boards both uses a 8051 a 27c512 rom and sram hm62256, in the first board i need the program running as is, however i need to develop my own program for the second board. but my trouble is that i need to get access to some data from first board static ram is not easy because each board have wr rd and cs lines. Just i think that maybe i can omit the ram in second board an try to connect to the ram of first, look at google but no lucky, spoken to some tech friends and tell me that it´s imposible. in this case i prefer another opinions, the only that i found is some circuits whit 74ls139 but this circuits is for drive 2 rams but dependig to the same processor, same thing whit 74hc595. I really appreciate any advice o a light that can help to me keeping forward whit my project.
Thanks In Advance
