Glenn: FYI - I just received back some pricing for PCBs for a different project. Whole PCB Hard Gold plated:

QualityPCB.com
10 PCBs - $218.28
25 PCBs - $253.52

Gold Phoenix Technology
10 PCBs - $179
25 PCBs - $280

So QualityPCB.com wins for larger orders. Wonder how they will do with that Adapter, not that price was 100% of the concern but I'd like to know for my notes. Soldering is still the major issue of course.

What size were the PCB's?

ViewMaster EZ will allow you to do that. WinQCad can panelize boards, but its kind of strange. The makers of WinQCad act like you are hurting a puppy if you ask for help panelizing boards.

I guess we don't have a choice. I just don't like the synchronous part.

Two clocks - one for the RAM and one for the host

Glenn: The PCB is small I guess. It's the size of a small Apple II card - about 4" x 3" with an edge connector.

As far as SD or PS RAM, I'm still not done researching our options. I'm going o get in touch with Micron and see what they offer. They may have a TSOP version of a PSRAM that we can use that just isn't widely sold or something. Worth asking though. I'll let you guys know what I find. Keep your fingers crossed.

You guys know about www.findchips.com

Right?

Type in a part number and see where you can get it. It makes price comparison fast too.
