 good maaan.  that's one.

 $150 shouuld cover 1 SO-DIMM revision _if_ there are 10 people.  the
first step is to get a working SO-DIMM.  that mayyyy take a few
revisions ($500 a time, 6-layer board.... *sigh*...) but once started
it's worth sticking to and finishing the job.

 so, there are three steps.  four.

 0) we get the pin-outs from Si-Chang (or i just reverse-engineer
them.  i have A Plan for that).
 1) initial design. takes... ooo... 6 weeks?
 2) PCB revisions until 1 SO-DIMM works.  this is the long bit: they
need to be sent to me, to test.
 3) N samples get done and shipped to whoever wants them.

 i remembered about jtag, forgot about serial port.  easily done,
thanks for flagging it.

 willdo.  i'll wait to hear from james, see what he says.  he needs
some money, which is why i put $2500 towards him, it's easy for him to
adapt what he already has, and it helps us.
