While outputting DVI! I wouldn't be surprised.

  Mouser have 64 megabyte PSRAMs. I really want a Mac System 7 grade operating system for this chip...

    No they do not. 64megabit

      Did you bother to check? It's octal, not QSPI, so I don't know if it's compatible. (edit - and 1.8V, inconvenient)

        Octal PSRAM usually cannot fallback to quad mode like some octal flash did.

          Actually reading the datasheet[1] it doesn't look like it. [1] https://www.mouser.dk/datasheet/2/1127/APM_PSRAM_OPI_Xccela_APS25608N_OBRx_v1_0_PKG-1954871.pdf https://www.mouser.dk/datasheet/2/1127/APM_PSRAM_OPI_Xccela_...

        Did you? It doesnt do qspi mode
        • rvense 2y ago
          Of course I did. If you also did, you would know that they do in fact have 64 megabyte PSRAMs as I stated. So a helpful comment would have been "they're not compatible, though". Your reply as it stands just makes it sound like you maybe assumed that I don't know the difference between megabits and megabytes.

    I'd settle for Mac 512K ;) https://github.com/evansm7/pico-mac/issues/7 https://github.com/evansm7/pico-mac/issues/7
