The Macintosh Portable was possibly one of the coolest computing devices to be seen with back at the end of the 1980s, providing as it did a Mac in a slightly nicer version of the hefty luggable portables of the day than the PC world could offer. Inside was a mere 68000, but it ran Mac OS system 6 and looked light years ahead of any comparable PC in doing so.
Back in 1989 it wasn’t even the norm for a computer to have built-in Ethernet, and WiFi was still a gleam in the eye of some Dutch engineers, so how has [Joshua Stein] managed to get his Mac Portable on a wireless network here in 2023? The answer contains a few surprises.
When seeing a WiFi upgrade for a classic retrocomputer the usual expectation is that it’s done by emulating a modem connection to the Internet over a serial port. But this wireless network card is a bit different, it’s a real network card capable of being used for much more than just connecting to the Internet.
We have to admit to not knowing that there were SCSI Ethernet interfaces back in the day, and it’s one of these that he’s created. He’s building on a decade’s work in producing disk emulators for the SCSI bus, and he’s taken the code for a Raspberry Pi Pico version and adapted the SCSI driver part to interface with the onboard WiFi on a Pico W. Altogether it’s a beautiful piece of work, and you can color us impressed.
