RE: [jornada] Found PCB Manufacturer

Mark,

It looks like I have about 300 (very approximate!). I also have about 25
blanks that could be assembled into boards.

The tasks that I see for doing more of the existing board:
        1) parts selection (verify DRAM manuf/timing/pinouts) [the
                flash is pretty easy]
        2) assembly
        3) programming flash/test [requires a test jig
                with the opposite side Molex connector since I can't
                find out where the JTAG pins on the 720 motherboard are]
        4) distribution/user assistance

I ran out of time (and somewhat money) internally for (2) and (3 -- the
jig design/manufacture).

Thanks
jca
