Hi
Im trying to understand how to add my own chip to read the data.
the chips are very similar to say 27C010 but with a few pins in other locations and also thc ROM is just 28pin not 32pin
128KB ROM in 28 pin package
only things that is different is:
OE on the eprom is A16 (pin 24 on eprom) on the ROM and pin 28 on the ROM is VCC (on eprom its NC)
Can someone explain how I can add a custom device for this?
I have read the rom successfully by manualy re-routing the pins with wires
regards

Use the correct device class.
Could you explain how to add a custom chip, your comment is beyond usefull
All the details are in the devices.txt, simply read it. |
