Would going online with a NetUSBee prove the RW Line of the ROM Port?
AFAIK no cartridge has ever been created to use a modded cartridge port to include RW.

Just because a lot of people agree on something, doesn't make it a fact. ~exxos ~

MIDI was tested by me, with a keyboard on input and a Yamaha synth on the output using Notator.

Thanks btl. Will update the MIDI part in the table.
For the Cartridge RW nothing can test that at the moment. It's a new feature on the port for new carts to use. Without anyone building a cart to use this and software to test at the moment it will stay untested until then. Only test so far is that it isn't affecting existing carts.

Ah, i see. Doesn't affect my notator Dongle, at least.
Also, I can confirm that my SF354 works on the external port. One thing to mention, the drive motor on the external drive is active as long the internal drive is accessed.

Thats a "bug" in the original ST design. I did talk about this somewhere ages ago. It could be fixable with more logic, but I wasn't really sure if it was worthwhile doing. It might fit in the H4's 1.44 GAL, but a problem for another day

I just tested this with an UltraSatan Mega adapter. It works.
Thanks, I updated the table
