How to Connect to a Server with No Modern SSL Ciphers

I recently acquired an old SonicWall firewall/VPN endpoint and would like to be able to access it. Unfortunately, it doesn't connect over HTTP and insists on HTTPS. Every browser I've tried no longer supports connecting to a system with such an old set of ciphers:

$ nmap --script ssl-enum-ciphers -p 8000 ip.add.re.ss

Starting Nmap 7.31 ( https://nmap.org ) at 2016-12-20 09:21 EST

Is there any way besides finding an old version of Firefox to install that will allow me to connect to this?
