The A1200 would have had at least a 68030 with 28Mhz or 40Mhz . Ram would be upgradable via standard PC ram allowing at least up to 32Mb.
The A1200 would also have as standard a low spec Picasso96 compatible 1Mb RTG graphics hardware built in with a slot to optionally upgrade it. A built in Scandoubler/Flickerfixer would have been a great addition too, but if that would have been too expensive then a slot/connector for an optional one would have been good

Another nice touch would have been an external 40pin IDE connector as standard for the cheap and easy installation of IDE CD-Rom.
