Duo R vs Duo

[GohanX]

I think you can use a Genni/SNES/NES power supply for the normal DUO though I believe as well.

None of those are the right size, although Console5 sells adapters that will let you use a genny 1 supply. DO NOT use a NES supply with it!

We all know the most superior hardware version is the Laseractive...

Dang, and there I thought, it was digging all the chips out of the dump and then soldering them to a breadboard and have a working system afterwards....

NEVER USE NES POWER SUPPLY WITH ANYTHING BUT NES.

the Nes power supply has helped me get many things cheap. Get offered various broken game system, cd attachment, see Nes power supply being used

I blew a fuse in my Sega CD using an NES power brick,

[780racer]

Welp. Sorry for the wrong info. I thought one of those power supplies worked on a duo system.

[tbone3969]

The fuse is super easy to fix in Sega CDs.  Just cut it out and solder the wires together.  If you want to replace the fuse they are cheap to order.  I have bought 3 or 4 model 1 Sega CDs on eBay in "as is" condition "will not power on".  Fixed the fuse and bingo, a functioning system.

Just go ahead and send me one so I can test....... how well it works....

Let me clarify my questions:

Are the R and the RX the same PCB? Is the power socket different?

How many different power sockets are there amongst all Duos? I'm not interested in wattage since they are all the same, just the sockets.

Btw, this "clutch" thing is news to me. I have no doubt that the RX CD-ROM assembly would fit a US Duo, but I don't know if that's the answer to your problem where CD-Rs get the laser stuck. The reason I say this is because I actually have a US Duo CD-ROM drive in my Duo R and no CD-R has ever jamed that system. The US Duo the drive came from would jam however, so I think that "issue" (if NEC even knew it existed) was probably solved in the controls somewhere.

I may be contacting TheSteve soon so he can adjust my pots again, and see if he can sprinkle some magic dust on my Duo as I have had issues with it since purchasing it a while back.

I dont blame anyone, its just a super old CD based game system. Just annoying that like most of the great games dont work on it, because of "Some" reason. Makes troubleshooting hard as well. since some games work.... They just happen to be the ones I am not extremely eager about..

The Duo R/RX have the same power supply. Off the top of my head, the Duo R/RX, GT and Super CD-ROM have narrow ac adaptor sockets, while all other first party hardware have the same size socket.

the only reason for the clutch is so the laser doesnt get stuck
the clutch can be transplanted from a RX drive to any duo, just swap the gear
the control system (hardware and software) is identical between systems, even the CDR2 (CDR2 has a slip drive mech, as was common at the time)

[SignOfZeta]

Then we still have no idea why black Duos move their lasers too far? I had it happen only a few times with my US Duo, but I've been playing CD-Rs on that same drive in my Duo R for 5-6 years and it's never gotten stuck once. That is, the October 1992 US Duo's drive now lives in my Duo R and it's apparently in-killable.

Such a mystery...

[Necromancer]

OldMan explained the stuck sled as being caused by.....

Poor reflectivity. The laser scans for the TOC at the beginning of the disc. When it can't find it, it has to seek to the end of the disc to reset. From what I've been told, the 'end of the disc ' is recognized by a change in the laser signal in the outer tracks. (The empty ring at the edge of the CD). Old grease and other problems can cause the laser to stick there, since it is not an area normally reached by the laser. It is worse on newer, larger cds, since the edge ring is (slightly) farther out.

So perhaps you've not had problems since transplanting the drive because you're using better discs or due to fresher lube.

No..  we do not.
