spreadsheet on unix

I am looking for a small text base spreadsheet running on unix platform, so I found sc. Many of the original code was written by James Gosling (father of Java), but is not easy to use as compare with Lotus 123. Sometimes technical is not a big issue, is the other part of the software like the interface which make the software a killer application. I compile sc-7.16 on solaris, bison and ncurses was needed, ncurses will replace the some of the original header files eg. curses.h. The sc need terminfo to run, I just keep the vt100 terminfo in /usr/share/terminfo/v/vt100 I found a copy of the very old Visicalc spreadsheet, allow for downloading, but just for personal use.
