The Trailblazer was a dialup modem.  I had the ISA card version from
which I carefully unsoldered the UART and replaced it with a socket
in which I put a 16550 UART which had a FIFO that made things run
a lot smoother.  No MAC, though.

The Netblazer did have an Ethernet interface.  Never used one so
I couldn't tell you if the MAC addresses were oddly repetitive.
