3DO M2 Dev Card Revisions

Anyone knows the differences between the various revisions of the 3DO M2 dev cards? I've got a rev. G dev card and compared it with a rev. H card, and seeing the differences, I thought we could compile a list. Here's what I have so far:

Rev. G:
Year: 1996
Ports: External Drive Box (also: joypad/audio), S-Video, Composite Video
Chipset: Prototype M2 chipset with 1 PPC, BDA 2.0
SDK: 2.0 (first shipped), also supported by 2.7, 3.0, and 3.1

Rev. H:
Year: 1996
Ports: Same as Rev. G
Chipset: Final M2 chipset with 2 PPCs, BDA 2.1
SDK: 3.0 (first shipped), also supported by 3.1

Looking for more information!

 

do you have photos of the 2 ? mine are pretty boxed up but i think i have rev h in both boxes

 

checked at least one of my cards is a rev h since i have photo of that with sticker =)

 

depends most of the early revisions would be internal by 3do i think and with higher revisions going to close developers and big houses till further down the road they hit the normal production studios
