OK, I know little about 35MM, to be sure, and so I ask ...
I was wanting to buy a 35MM cartoon short, and i was asking the seller if it could be put on a reel, and our conversation wandered onto "platter" or "reel' 35MM projector. The seller of the print said that there is no difference.
I have seen those large "platter" 35MM's from time to time, but i must admit that i just took a "cursory" look at it. '
The question is ...
Are "platter" 35MM projectors capable of taking an old school 35MM "reel" of film? I would have thought that, being that an old school 35MM projector would have arms for the front reel and the take-up reel, that those more modern "platter" projectors don't have the arms for an old school reel?
Am I wrong?

The platter is a completely different set of gear from the projector. It, and towers, will hold the entire program of 35mm. The film feeds to and fro with the projector.
However, most 35mm projectors will have spool arms just like a 16mm or 8mm.
If you wish to buy, I suggest you ask for the film to be supplied on a core.
I'm not too sure about the US but here, in the UK, different makers of 35mm projectors had different sized spool spindles, hence the fact that cinema films here would always travel on cores, and at the receiving cinema it would be mounted on spools, and eventually returned on cores.

35mm film is usually shipped on "cores". This is a core.
There are several methods of handling film on a core. The most common is that the film on a core is placed onto one flange of a split reel.
Second side of split reel is screwed onto the first.
The film is now on a "reel" and can be run reel-to-reel on a projector, or rewound onto another reel, etc.
Trailer flanges can also be used to transfer a roll of film from a core to a reel (or from a reel to a core). I've never been in a projection booth or a private home setup capable of running 35mm that couldn't run a film supplied to them on a core though. It's pretty much a requirement, almost as important as having a lens in the projector.
If you want to talk platters, keep in mind all platter setups have to "load" the film onto the platter in one fashion or another. The "MUT" (short for "make up table") is the most common. Here is a photo of a MUT loading a film onto the bottom platter deck. (Note the reel is on the other side of the MUT, but it's the only quick photo I was able to find.)
Note that even in platter houses, the film has to be loaded from a "reel" of some sort, whether that is a solid reel, a split reel, etc.
Just doing a super quick search on youtube, here is the first link I found showing film winding onto a platter. (Note there is so much bad film handling here I'm not even going to start commenting, but you get the general concept of how it's done.)

Hope that helps.
