Hi there, not sure if this is of interest to you all, but I recently moved one of my BlueSCSI v2 units into a 486SLC with an Adaptec 1542. I installed Slackware 3.6 on it just for some nostalgia and it worked really well, but I wanted DaynaPORT SCSI/Link support, so I wrote a new driver for the Linux Kernel 2.0 series to do just that. It's working pretty well! Getting about 65kB/sec down.
I might try an old 68k Debian release next in my Quadra 605 to see if the driver works on that hardware as well. I think it will, as it's a pretty high-level driver but I guess we'll see!
Here's the code if anyone is interested. Full disclosure: I'm a software engineer but not an experienced Linux kernel contributor, so I used Claude Code to fill in some of my knowledge gaps. Use at your own risk!
