The default number of items shown on a page is 20 and there seem to be more than 20 items in that category (Propeller Boards). When I changed the number of items to 40, it showed up.
It shows up as the fourth item when I click on Microcontrollers->Propeller->Boards. I ordered 2 a few weeks ago, and I'm using one of them at work right now for collecting data.
It's especially odd, since both pages have virtually the same headings:
"Development and accessory boards for the Propeller microcontroller."
vs,
"Development and accessory boards specific to the Propeller microcontroller."
The two product categories mainly exist because people search for things in different ways. For now the results display in a random manner (if the future it may become more hierarchical). Also, not all the boards we offer are development boards. We will adjust the descriptions accordingly to make them a bit less confusing, although there still will be overlap.

Jen, just out of curiosity, how do you characterize a development board vs. a non-development board? It seems that as long as it includes a Propeller chip and a way to program it, it could be used for "development." (But even then, I'm not sure what that means.)
I think this post from Ken, about the price difference between the Project Board and QuickStart, explains a little about what a "development" board is.
. . . these two boards cost us about the same to manufacture.
The reason the QuickStart is higher is because it's more like a development tool. The idea is that you need one or two, and then you can plug a bunch of modules into it. Further, it's a reference design and the price of it needs to reflect some level of support from our Field Application Engineers as typical customers include product designers.
The Propeller Project Board USB is priced low because we build them in mass and want to encourage consumption of them in projects.
I think Ken left out the word "dozen" when stating how many QuickStarts one needs. IMO, "one or two" should be "one or two dozen".
Update: The 'Development Boards' product category has become simply 'Boards' today.
In addition, the sub-categories of 'Breadboard' and 'Through-hole' have been added to the category.

I have quite a few QuickStart boards but now I want a Spinneret Web Server 2.0!
I have one QS that I continue to reuse, since it's the only one I haven't butchered by adding components, cutting traces, etc. It's not my go-to board for experimenting, though, in large part because the pins on the 40-pin connector are not silkscreen-labeled; and the add-on labels -- even my own -- are a bit cumbersome. For experimenting, I'll almost always choose my Prop Demo board first, followed by the Prop BOE, then the ActivityBoard.

I have a number of QS boards because I have various other boards plugged into them and it's nice not to have to reassemble the stacks every time I want to test a different configuration. Of course, I'm only really doing tools development. I never see to have time to actually use any of my Propeller boards for actual embedded applications. :-(
I have been away a while and recently found the Propeller Project Board USB, and I am impressed!
I'm sure I could suggest some changes to it for my own needs, but this thing has so many options, It is great!
That said, has anybody made use of that smt area on the bottom for a good chunk of SRAM or SDRAM?
I would really like to see a Parallax board with more than one propeller on it to introduce people to the idea of using multiple propellers and communications between propellers, etc. I think I will just have to use a few of these instead ;^)
I've played around with Jazzed's TetraProp. It has a lot of potential for a multi-prop platform. I just never get past the "playing around" stage, so I can't go into much detail.
Duane, your OctoProp looks downright intimidating.
Steve, can't wait for your TetraProp2 - it should really have some potential!
Does anybody know if the 3x4 Blank Proto Board(45305) holes line up perfectly with the Propeller Project Board USB?
I just checked and no, the Blank Proto Board does not line up with the the holes of the Project board. They do line up with the Propeller Proto Board holes.
I haven't used SRAM on the Project board but I have used the smt area. I initially thought the smt area was a waste of space but now I like it.
You know jazzed sells the TetraProp boards bare right? I purchased all of mine bare and followed Cluso99's instructions to populate them.

It's there. I searched on the part number, and it came up with 209 in stock.

Oddly, these two pages have different products:
http://parallax.com/catalog/development-boards/propeller
http://parallax.com/catalog/microcontrollers/propeller/boards
vs,
"Development and accessory boards specific to the Propeller microcontroller."

exactly.
Enjoy!

I seem to recall a Forum member creating their own multi-Propeller boards. One of the boards was a quad. Can't remember the member's name though.
***AH! Got it:
Mikronauts.com
***rats! Mikronauts has a dual but not a quad. I still forget who made that one.

I've also cut a few of mine up to make small single or double Prop boards.
Half of a TetraProp made it easy to add two Propeller to my robot remote.
I have yet to do anything useful with this monstrosity (but I think it looks kind of cool).
I really like by TetraProp boards.
Duane, your OctoProp looks downright intimidating.

Thanks! I've been really busy just lurking!
...that's right - sorry Steve!
Are there any sram or sdram projects that someone has done with the project board since it has that nice surface mount area?
Does anybody know which breadboard they show attached to the Project Board USB?
Thanks in advance,
