@zarf Definitely BorderZone, Sherlock and Hitchhiker (Solid Gold). I tested these interpreters last year for the Puny BuildTools. I can confirm it’s a similar logic as the Atari 8-bit, though not the same. I was able to get my own games running in Infocom’s late Atari 8-bit 2-disk interpreter but never managed to get anything running in the Apple II 2-disk terps. I also suspect some of the Z4 games on the Apple II to prompt for a disk swap, e.g. Trinity, though I haven’t tested this.
@Warrigal The statement that Infocom’s late Atari 8-bit interpreter has the resident memory on one side of the disk is not entirely true but somehow made its way into the Z-Machine Standards document. Instead Atari 8-bit story files for the late interpreter set the resident memory marker to 8FFF, regardless of its initial value, and the story file is always split at the 8FFF offset, which is roughly 36k. I wrote an article about it some time ago when I managed to get things running in Infocom’s late terp. Z-machine standards / Atari 8-bit targets
@heasm66 I talk about the Atari 8-bit disk sizes in the article I linked above
