Yes, I do indeed! That's what we used to design the actual PCB, figure out how the address space works, etc. I've got some MPW scripts for building the declaration ROM. I'm working on the actual Ethernet driver part just now, and hopefully I'll be able to embed that in the declaration ROM too. The great thing about classic macOS is that you can talk to hardware from userspace by just reading & writing the appropriate addresses in memory. Of course, this is also a terrible thing :-)
