There is now a final rough draft of the eval card schematic at < 
http://tinymicros.com/embedded/LPC210x/lpceval.pdf > 

    The 1-wire interface is not complete.  I'm looking at Robert Adsetts 
requirements for the 1-wire support for his library.  This may require 
moving a couple of I/O pins around, as his code wants to use one of the 
match outputs. 

    The SD/MMC card will support SPI mode, but not the 4 bit wide SD 
mode.  Besides a shortage of I/O, I believe it would be very difficult 
to get the SD 4 bit mode implemented in software to get very close to 
the SPI mode in hardware.

    Missing items are still 'scope ground loops, some points for 
measuring current, some other minor details.  I'll be going over these 
in the next couple days.

    In the case where a SSOP or SOIC part is available, I'll be choosing 
the larger form factor.  I honestly don't know if I can afford to 
produce finished cards, but I will make raw cards available, along with 
the CAD files to produce your own at some place like < 
http://www.4pcb.com/33each >.  Finished cards would require me to have 
enough guaranteed orders to have the boards assembled at a local board 
house, and in low quantities the setup charges would probably eat me 
alive.  I should be able to at least offer all the R's and C's, 
regulators, and other nickle and dime parts. 

    I have managed to order samples for just about every IC on the 
board, excluding regulators.  The parts come from 6 sources: Philips 
(LPC2106), Microchip (MCP23016), Maxim (MAX3227E, MAX3245E, DS18B20, 
DS2401, DS2411, DS1337), Analog Devices (AD7997), National (USBN9603), 
and Ramtron (FM24CL64).   Many people may not care about the AD7997 A/D, 
and the Ramtron DM24CL64 can be replaced with a Microchip 24C64.  
Everything else (so far) is a Digikey item with the exception of the 
SD/MMC connector, which comes from Mouser.

    Any suggestions are welcome.
