Can anyone tell me the intended use for the "T-slots" cast into either side of the banjo?

The slots are intended to hold attachments, of which there is only one that I'm aware of...a duct collection hood, like in the photo below.

I just ordered a PM2020, and don't see that as an option. Can you provide more details regarding this? I was trying to figure out dust collection for the lathe ice it arrives.

I did a Google search on various terms like "Powermatic 3520B dust collection", but couldn't come up with any retail suppliers. Not even eBay has one for sale that I could find. There's a brief note about them through the link below, but that's all I've found online.
However, I have one that I don't use any more...bought it when they first came out several years ago...photo below. Shoot me an email if interested: yoyo@yoyospin.com

Ed, where did you get the yellow dust hood in the photo? Looks like a good one.

I'm not Sir Davidson but I bought two like that from Woodcraft. One came in a kit with a piece of 4" stay-put flex hose and some fittings:

It's amazing how well this works on the lathe.

Yep, that Woodcraft set-up is what I have. Like it a lot...

There was recent mention on the AAW forum of the dust hood Powermatic used to sell. Not available anymore apparently.
Seems perfect for a home-made hollowing rig

I have a 3520B and it does surprise me that the banjo t-slot has not been put to more use, for instance a small hollowing system that would allow you to slide the holding device sideways by loosening a few wingnuts.
