Since the Rev. 10 release of Romy I've been considering possible uses for the new free I/O pin. One possible use was to generate a /WE signal to support flash memory writes for A3000/A4000 owners using Flash memory adapters (are there any?).
This would require connecting a jumper wire from the Romy adapter to the Flash memory adapters. However, I would strongly recommend a jumper or switch to disconnect the /WE signal from the Flash memory adapters.
If there's enough interest in doing this let me know here or on Amibay.
