Title: RAU-30 to CD-ROM2?

Does this configuration actually work? Would it work with a SuperGrafx? The CD-ROM2+SuperGrafx is a monster, and wouldn't really fit on a shelf. My worry is that the black cord on the side of the RAU-30 will prevent the CD-ROM2 from plugging all the way in. I don't have an RAU-30 to test with, and googling, this is the only picture I could find of a similar configuration.

I thought that the LT had its own (very rare) Super CD-ROM2 adapter?

I've seen pics in the past of people hooking an RAU-30 to a SCD, but can't say for sure if it really worked.

If you're going to use a SGX + SCD anyway, why not just plug them together directly and just spin it 90 degrees? That should take up less space that an RAU-30 connection.

That picture actually includes the rare lt scdrom adapter. so no reasonable option. (https://emoji.tapatalk-cdn.com/emoji6.png)

What's it called? How does it differ from the RAU-30?

It's the PI-AD18. Looks like a simple extension for the LTs ext bus. Never opened mine though.

It'd be interesting to see a side by side photo of the two CD-ROM adapter's ext port connection ends.

Both look identical

IIRC, the adaptor is just a short pigtail that gets around the problem of the port being blocked.

Btw, sorry to be pedantic, but when the hardware list is as huge as NEC's, I think it's important. All PCE drives are known as CDROM2. The one in the pic is the Super CDROM2.

I made some pictures for you. Please see below.

Guts of the PI-AD18. As you can see, it's nothing more than an ext. bus extension with additional power  port.

Thank you for those photos! Excellent. :)

Awesome, that's exactly the kind of difference I expected. :D

I'll dig mine out tomorrow and check, but I am sure I have tested this in the past and it worked fine... I also don't think you need the LT Adapter and the RAU-30 connects directly onto the LT.

Looks like I don't need to...
