Hi Dave,

I'd be happy to help with testing.  There's a SCSI2SD card (uses
a micro SD card up to 64 GB) that works pretty well on 68k Macs,
though I've had some problems with it on faster systems (such as
PowerMac 61xx). The SCSI2SD also didn't work using the traditional
method to install NetBSD (Mkfs in Mac OS just didn't see it for
some reason); I didn't test it with sysinst.  But it works ok an
a IIfx running Mac OS and Debian 3.1.

Linux 2.x seems to get around 200 KB/s on the Mac LC III; Linux 4.x
gets around 100 KB/s. NetBSD 8.0 installed from CD at about 25 KB/s,
though that included decompressing the tar files.

I have an Asante EN/SC and could help with testing of that, too,
though I'm not aware of any drivers for it (Linux or NetBSD).  And
the lack of documentation would likely be a problem.
