Then, of course, that would have to be broken down by serial numbers. Meaning, at what serial # would much of the problems concerning the early version of the ADAM console have been addressed?

The Seriel # theory may not actually be a good way to go concerning the ADAM as there was a plethora of returns after the launch of the ADAM Computer, as I'm sure you have heard. While there were a lot of systems that did indeed malfunction (usually the Printer or the Digital Data Drive) and need to be repaired/replaced, there was also a lot of user error and misunderstanding in how to properly use the system and what to do/what not to do. So, after these systems were fixed or tested to be functioning properly, I assume they would have been repackaged and sold as new once again with the same Serial # stickers on them. Does that sound plausible or would the Serial # stickers have been replaced and the old Serial # never reused? Anyone?
As far as the Expansion Module #03 ADAM versus the Stand-Alone ADAM, there is no clear cut breakdown as to which one is more reliable and from my personal experience over the years, I would have to rate them pretty much even as far as reliability. The Exp. Mod. #03 ADAM would probably come out ahead because of the simple fact that there is a lot less under the hood (No ColecoVision motherboard, No RF/Composite Video board and Audio output) than the Stand-Alone ADAM... but then of course you need a separate ColecoVision system which could offer up it's own problems. At least with this CV & Exp. Mod. #03 setup, you bypass any possible CV Power Switch problems due to the fact that the ADAM Printer powers the whole lot and you leave the CV Power Switch OFF at all times.
There were quite a number of revisions of the ADAM Logic Motherboard, but most of them dealt with tiddying things up and doing away with a lot of jumper wires.
As far as the Digital Data Drives, there were three revisions of these and the one that you want is referred to as the "New Japanese JVC Revision". The motor mounting screws that you can see through the clear plastic door are arranged like this:
..........*.........*
*............................*
..........*.........*
These latest revision drives offer a variety of improvements (both visible and not unless you open the drive up) over the two earlier revision drives that have a screw arrangement like this:
.......*...............*
*.............................*
.........*...........*
Ignore the Periods in the above examples and only refernce the Astericks (they represent the screws).
Anyhow, good luck if you take the plunge as most people won't be able to help you much in figuring out what revision system, drives and printer they have.
