I realized that there are at least two different PC-FX revisions out there... Serial # 5103451YA = older BIOS, the one commonly used by emulator users This one has a paper label on the back  Serial # 6402801YE = newer BIOS This one has embossed print instead of a paper label.  |

Interesting!! I have the second one. I didn't know there was a paper label version!

You may be lucky. About 90% of the ones I see on ebay or yahoo auctions japan are paper-label, and this seems to reflect the relative numbers actually produced. It also seems that the embossed ones were from later in the production life cycle.
And if my two units are any indication (probably false), the later units may have fewer problems (though maybe because they’re slightly younger or less-used during their lifespans).

Very interesting indeed! I just bought whatever was cheapest in 2004, ha ha. Definitely makes sense that if there were any revisions, the newer group would be smaller - they knew this thing was a failure from year one, I reckon. This also seems to indicate that they at least sold through the initial batch they made, which is an interesting data point I hadn't thought about much before. I've definitely not had any issues with my unit, and it's one of the few non-sega consoles I haven't had to recap, so that's something!

I got another embossed machine the other day - with good laser action - and its serial number was 5808279YC.
My theory about the serial numbers is that the first digit is the year (i.e. '5' = 1995), the second digit is the month (8 = August; X/Y/Z = October/November/December), and the next group of numbers is the unit number within the month.
...And the last character (in this case, 'C') seems to be some sort of hardware revision.
So this new machine would be unit # 8279 of August 1995 (if I'm right).
In any case, the embossed back case seems to have become available as early as serial 5808279YC.

Just as an update, since this conversation I've discovered that my laser is indeed in bad shape somehow or other, because it hitches up on video scenes, which for the PC-FX is kind of a lot.

Looks like mine is the more common paper-label: Serial Number 5404163YA
The paper-label is identical to yours, Dave
