Mike,
I just soldered few diodes and ready to wire it up, but I will look if I have any of the 07 chips or any open collector stuff first. I may..
Could you comment of this , I am currently pushing the chip limits using standard 5V I/O and I do suspect the interface may be the issue.
I have not look at the SPI clock speed settings in software, but I put some delays between write and read cycles.
I am using SpiRAM - SpiRam.read_stream / write_stream. So far no real issue with the code.
Cheers Vaclav
