At this time, as near as I can tell, neither Windows 8.1 BIOS, nor windows 7 BIOS sees the drive.

If the drive doesn't spin at all then there is a huge chance for the problem to be ROM related (like damaged FIPS) or electronic related. If so the chance for recovery is high.
If the drive does spin then the next question is does it produce strange or abnomal clicking or sounds normal ?
If it produces clicking or strange sounds like spindle trying to spin but without sucess or heads hitting the limiter (DO NOT OPEN THE DRIVE) then it's BAD news because most likely clean room will be needed to recover the data and it will be expensive (more than $500 USD).
If there are no strange clicking then the drive might have firmware issues like damaged A-List causing a LED error. On those cases the TTL might be of some assistence but the OP will need tools and experience to make the drive work again.
Does the drive stops after a short while after power up (if it starts to spin at all) ?
The anwser to my question might provide more clues about what is going on with the drive and if it's possible or not for you to solve it by yourself (not likely).
What you describe so far leads me to believe that the problem is not "logic" and there is some phisical issue with the drive, as stated. Either mechanical or firmaware.
Do you intend to spend any money at all to get the data recovered ?
For firmware (on the platters) problems you will need (more or less expensive) tools and the adaptor. For ROM problems you will need either firmware tools or a eeprom programmer. Buying a new PCB will not work as swaping the ROM chip might be required, unless you are lucky. So even if the problem is with the PCB buying one on ebay might not be an option unless you exactly match the firmware version. Firmware on the ROM chip of the PCB must match overlays written on platter or it will not work.
If you are looking for a cheap alternative done by someone that takes Darta Recovery as an hobby (and not a profession) - ME - then the fix for the ROM problem or the firmware problem would cost you, let's say $40 USD + shipping costs to and from Portugal. If a PCB is needed then the price for that must be added as well. If the problem is heads related i can't help you out and you are adviced to use the services of a professional as opening the drive in safety requires lots of experience and a clean room or laminar flow bench with class 100 filtering.
A TTL adaptor to further diagnose the problem as mention is this :

When connected to the drive on the following way it will provide further details on drive status :

Then with the use of tools like the following and with experience and knowledge the firmware problems can be fixed to regain access to the data.

Of course the MOST IMPORTANT part is to diagnose correctly the issue with the drive, so please reply to the question that i have made.
Using firmware tools or TTL will not mean a thing if the problem is with a toasted PCB or shorted TVS or bad heads, etc ....
Regards.
