They are similar but from a schematic viewpoint they are totally different - not only the BBD has been replaced, the complete circuit was reworked.
guts are always welcome, especially since I don´t trust the EH-1317 (SAD1024A) factory schematic.

The SAD1024 with Edge model DID come first, I don't think there's any question of that.
The earliest I can see any MN chip being used by EH was in May of 78, up until January in 78 they were still designing with the SAD1024 for everything, an EHX member did pop up on the EHX forum some time back and confirmed that once the MN chips were released their products were redesigned to use them as they were less noisy and more reliable which if you look at the products checks out.
It's a nearly 40 year old memory, man... (pun was not intended but i'm glad it worked out)

was definitely 78. by 79 my friend had moved to like new zealand or something with his folks. he wasn't there (what would have been) my senior year
