Jim Sorenson has posted an update on his blog regarding the Ron Friedman auction that he won that contained the preliminary script for Transformers: The Movie (that's the 1986 film).
"Last month, a group of dedicated fans pooled their resources to attempt to purchase a piece of Transformers history; scripts and other documents from Transformers movie writer Ron Friedman. Many scripts were won by our coalition, but perhaps the most anticipated among the many documents we purchased was an early draft of The Transformers: The Movie, dated 4/27/1985. I've scanned it in and done a preliminary OCR pass, so without further ado, here it is for download!"
The script contains the dialogue for many scenes that did not make the final draft including Megatron's reference to his "Spark", action for Sunstreaker and Wheeljack and the how the fate of Earth was also going to hang in the balance. Some of the information was already known about, like the Predacons originally being Autobots called Anibots, but what is new (at least to us) is that their names were finalised as Simba (Razorclaw), Pardo (Rampage), Shriek (Divebomb), Thump (Headstrong) and Clump (Tantrum). Other new characters are Stripes and Stinger two other cassettes for Blaster. Form the script its obvious that Streeljaw was to be called Cubbie, a Tiger was going to be called Stripes, a scorpion was going to be called Stinger and there was only going to be one robot, Bolts. We had heard rumours of a scorpion cassette many years ago, but always put it down to the watch scorpion confusing people as we could find no further evidence.
