RAU-30 Rubber Caps/Feet?

[csgx1]

I recently set up my SuperGrafx with a briefcase CDrom2 and can't figure out what the pair of black rubber caps that came with the RAU-30 adapter are used for ?  I'm sure the answer is obvious but just not to me.   I googled and searched here but didn't find an answer.  Also, the instructions don't illustrate anything and I don't read Japanese.  Thanks in advance.

One of these I'll check in my RAU-30 box and see if I have those as well. I don't recall ever seeing them. I bought mine brand new, so if I ever had them, they should still be in the box. I wonder if whomever you bought that from didn't just throw them in by mistake.

Initially I thought this but after some searching, I found that some eBay auctions also included them. 

I actually stole the above pic from an eBay auction...

They're caps for your nipples. 

Once you start playing a full on SGX+CD setup, you will find them perking up in excitement, and in need of shelter that only PCE related products can give..


yeah. I'm going to log off now.

Holy shit....this is gold. I just bought an RAU-30 and just found this post. Nipple covers.

I would like to enter this raffle.

Thank you.

Yeah, I tried fitting them on but unfortunately they're not my nipple size.

Seriously, I still haven't figured out what they're used for.  Anyone know?

Bumping for an answer.

They are intended as a protection for the 2 stereo plugs from the av cable, since you are instead using those from the ifu when using the rau-30

It is mentioned on the included wiring instructions (above, next to no.1)

Awesome, thanks for letting us know.  That makes sense and I didn't even consider that idea. 

After many years, I can finally get some sleep and not contemplate anymore on what the mystery of these caps were used for.

I, too, can rest peacefully now.

Good, but now I need to find a good supplier for nipple covers.
