distro for an older tower.
 

I have a working tower with these specifications: pentium p54cs processor 166mhz 66mhz bus speed
CD reader, tape drive, 128M ede ram, 5 1/2 floppy, 3.5" floppy, serial keyboard, no mouse, barracuda gard drive, soundblaster card, isa ether net/cable networking card. It works.
What can I install onto it.
The hard drive is separated into logical partitions and I think it is either 2 or 5 gigabytes.

I'd start with slackware, or DSL(damn small linux). There are a ton of options though. Ubuntu would even install off the alternate CD, but you wouldn't want to run it. You might try Xubuntu.
