exxos's Atari, Amiga & retro forum

There are numerous successes etc around everyones build log but we wanted to make a list of what has been tested so we can cross the list off and know that the H4 is sound.

Please add to the thread if you think there is anything missing that needs testing or if the status / comments need updating. Even if you have tested something on the H4 we haven't listed please also add to the thread.

Thanks derkom have updated the table

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

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.

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 :)

Internal Mega ACSI connector

Have not seen any reports of this being tested

I just tested this with an UltraSatan Mega adapter. It works.
