I have completed and uploaded editions of the Revelation of John based on the Robinson-Pierpont Greek text, and also another one based on the Textus Receptus. In addition, my previous eclectic edition of Revelation has added to it many more footnotes, and has been revised based upon what I learned from doing the other editions. There are now 508 footnotes in these editions, showing the textual variants, and the ancient witness support for each.
Here you can download the Robinson-Pierpont edition of the Apocalypse of John
or the Textus Receptus edition of the Apocalypse of John.
