Sadly, it looks like no official Adam support, according to Opcode:
About ADAM compatibility, the answer is no, and here is why...
First memory, the ADAM already has RAM memory mapped to the same range as the SGM. In other to avoid bus contention I would need to include a way to disable the SGM memory, since I cannot do that with the ADAM. I would do that thru a jumper (and risk having the user messing up with it), or do that by software. By software the SGM RAM would come disabled and every game should be responsible for checking if RAM is already present and enabling the SGM RAM if none is found. Complicated but possible, however...
The SGM also requires some I/O addresses. I checked with the ADAM user group and for my surprise mostly all I/O addresses are already taken by some ADAM device, Coleco made or 3rd party. In this case the only way to avoid contention would be to request the user to remove the conflicting devices.
You see, too much trouble.
I find it funny that Coleco made the ColecoVision so flexible and expandable just to close most “doors” with the ADAM. I suspect they were created by different groups.
This is particularly disappointing for those of us with Adams because of the clean video signal you get versus an unmodded ColecoVision.
