The board design is lossely based on the BlueSCSI V1 and the ZuluSCSI Pico. The RP2350 the MCU on the Raspberry PI Pico 2 is 5V tollerant meaning no level translation logic is nessasary. Like BlueSCSI this outputs 3.3V to the bus, which is compliant with LV SCSI.
Piers Finlayson's video on the RP2350 variant of one-rom talks about caveats this may have. The A4 silicon revision adds support for this https://www.raspberrypi.com/news/rp2350-a4-rp2354-and-a-new-hacking-challenge noted at the bottom.
Coming soon will be based on ZuluSCSI firmware
