Command Line only UNIX/Linux OS
You can Install "Ubuntu command-line system" and try Minimal CD.
The command-line version of Ubuntu is a sparse system without any graphical elements. It's a text-only version of what lies underneath all the advanced graphical elements. It's also the starting point for a minimal installation.
You can download following Ubuntu 32 or 64 bit minimal ISO images:
- 32-bit PC (x86)
- 64-bit PC (amd64, x86_64)
- 32-bit PowerPC
- 64-bit PowerPC
They are all smaller than 80 MB.

I guess almost all Distros have a minimal version without GUI. Dont know any below 80MB, but I suggest the CentOS minimal, which is around 400MB.
But there are distros below 80MB but they include both GUI and CLI. So I guess if 80MB is your limit you can use them and simply not use the GUI.
- Slitaz is just cool.
- Damn Small Linux (DSL) lol :D just 10MB.
