I've used it with 128MB and 256MB, but had much better response times on a server with 512MB.  That was on a system with 20-30 concurrent users.  Limit your Oracle SGA to about 50% of the total RAM (this assumes your server is dedicated to Oracle with nothing else running on it, if there are other applications, printers, etc. you will need a smaller Oracle SGA).  The size of your database is also a factor.  With 512MB you can have an Oracle SGA of about 250MB and database block buffers of about 200MB.  That usually gave sub-second response times in our 1-gig database with a few million-row tables.
Another important consideration is the number of hard drives - the more the better.  Fewer than six will likely mean you are limited much more by disk I/O than memory.  Avoid RAID if possible.

Depends on your way to connect as well. Oracle 8 is object-oriented so requires a huge quantity of memory. I think it would work fine if you use at least 512M.
