@here Ok, I'm going to make a plea.
The Apple II FujiNet's smartport interface behaves differently across firmware versions and smartport adapters.
We need help to understand _WHY_ and what we're falling short on.
We need people to help with a $10 USB logic analyzer and a copy of PulseView to compare the Unidisk 3.5 and other SmartPort devices against our firmwares, and see WHERE we are failing, to understand the timing tolerances, so we can figure out where to focus our efforts on the firmware code.
If you can help, please come to the Discord. https://discord.gg/2Ce9guX
