Yeah, I saw that after I did the CF research.  Too bad CF is so expensive.  It 
looked so nice and clean.  $130?  It's got to be cheaper to do a little 
research and build one yourself.  

-RIP-  

Opens and old unused pcmcia rs422/484S card a board marked with at Texas Logo 
and QATech INC SSP 290, listed for $130 in a QAtech price book.  Keithly 
charged me more when I bought it.  

It contains 10 major components

xlinix xc3030A - field programmable gate array, might be discontinued, 
available in Russia for less than $20/(unknown quantity).
ATMEL AT28c16 - 16k (8x2) eeprom.
TI/Toshiba TA550C - 422/485 UART
HT245
HC104
726 485 optoisolators?
crystal marked 18.432

The connector are neat the way the spacing just works to fit the pcb between 
the posts for a very clean surface mount.

Bleh, that's enough looking for today.  Between that and last monday's skim of 
the ORiely embedded programing manual, I'm ready for a beer.

Carefully reassembles card. Oh, very nice case design, it snapped right back 
together.  Too bad it did not work well when I bought it.
