I was able to find a couple of archives for SPICA on Wayback Machine since the download link in the first post is down:
https://web.archive.org/web/2018*/https:...astest.zip
(When you click on either of the links, it will pull up a page that says "Got an HTTP 302 response at crawl time". Give it a minute and it will download SPICA.)
