PV-Backup is the device, which can be used for the Nintendo-64 game console. This device is the link interface between PC and console. I made this device because I had a job to make and then to debug the program for N64.
The device uses 72 pins 32MB EDO SIMM. Somebody told me that he used the device with 64MB. This memory is the ROM emulator. The PC can access to this memory via EPP1.9 interface.
As result, the PC can upload the code to memory of N64. You can find all information for building this device on this page. You can also to use this information for self-education.
Device was used for making a N64 application (look at screenshot)
