SE/30 Multiple Serial Port Solution ?

[Admiral Ackbar]

Hi all. I was thinking-through a way to get a System 7.5 SE/30 to use multiple serial devices:

• MIDI box
• HAM radio TNC
• ImageWriter
• Vernier Lab box

I think there is a way to use a Raspberry Pi w/HAT to act as a kind of "switchbox", maybe emulating a device from the 80s or 90s that did such a thing? Can anyone comment on what might be viable in 2026?

Thanks.
