Leiden University has made available a facsimile of the Leiden Manuscript of Talmud Yerushalmi. Here's the blurb from the website:

Leiden Or. 4720 is the only extant complete manuscript of Talmud Yerushalmi. It was written in 1289 by Rabeinu Yechiel Ben Yekutiel HaRofeh from Rome. The manuscript consists of two volumes. The total number of folios in the manuscript including the binding and the blank pages is 682. The following links link directly to the University of Leiden Library website. The images are very large and may take a long time to load.

The quality of the scans is excellent, with even marginal glosses rendering clearly. Access the (unpointed) Talmud by clicking "Leiden Manuscript" from the left-hand column at:
