cool precision robot Motion CONTROLLER ICs PWM PID filter built-in

Hi,

I have the following motion control hardware PID filter ICs with PWM
output,
ideal for precision mobile robots (spare huge computing power):

MDIP package: http://www.national.com/images/pkg/n28b.jpg
Will throw in machined, high quality IC sockets for each IC.

2x LM629N-6 (6 is speed in MHz)
2x LM629N-8


If you design a very SMALL mobile robot, I have a pair of
extremely small SOICs (about the size of a 1-cent coin!)

2x LM629M-8

Here is prices at DigiKey: $39 and $24 each IC (they also have a
handling fee
I believe)

These are the best integrated PID filters with PWM output I have ever
seen.
Elegant design and SIMPLE implementation and programming - see docs
below)
Perfect for modular mobile robots: get the mobile base with these ICs
and
cool motor drivers like the LMD18200 and use ANY microcontroller/laptop
to
control it.

Make an offer - prefer to sell all of them in a single package. Accept
Paypal,
(incl Visa, MC, Discover, debit cards, etc) Money Orders and maybe
checks.

Make an offer I can not resist for all (will consider partial sale if
no offer
for the whole package is received). THIS IS YOUR CHANCE TO GET SOME
WONDERFUL
ROBOT PARTS AT A COOL (i.e. YOUR) PRICE. JUST LET ME KNOW.

(I do have 4 of the the LMD18200 motor drivers
used in application above).
