ANNOUNCING THE MINI BOARD 2.1 EXTENDED !!!

The Mini Board 2.1 Extended is the latest version of the Mini Board.
It is based on the Mini Board 2.0 Extended (see file
pub/miniboard/docs/mbextend.txt), and includes the following new
features: 

    *	full six-wire SPI jacks include power, ground, and all four
SPI wires.

    *	optional diode protection prevents reverse-polarity voltage
input when using DC power jack.

    *	power and ground on Port A headers may be bridged to motor
power and ground, allowing RC servos to be plugged directly into the
Port A header (when using a 5.5 to 6v power supply).

    *	extra space between PLCC socket and female header connectors
to allow for newer, slightly larger PLCC sockets.

    *	mounting holes drilled for single RJ11 jack (for RS-232
serial), saving money on triple RJ11 jack if SPI ports are not to be
used.

Download the file pub/miniboard/docs/mb21ext.PS.Z to see the
silkscreen of the new board.  


ANNOUNCING A NEW SOURCE OF BLANK MINI BOARD PCBs !!!

I am pleased to announce that Douglas Electronics, a Macintosh PCB CAD
software house and a commercial PCB fab facility, is a new distributor
of blank Mini Board PCBs.  Following is pricing info prepared by Bill
Schuler, a Mini Board aficionado who is responsible for Douglas's
becoming a distributor.  Muchas gracias, Bill!!

DOUGLAS ELECTRONICS MINI BOARD ORDERING INFO:


Pricing for the new mini-board is as follows:

------------------------------------------
1 board only  ................. $ 10.00
2 to 9 boards  ................    7.50 ea.
10 to 50 boards  ..............    6.25 ea.
50 and over  ..................    5.00 ea.
------------------------------------------

There is also a dollar volume discount on all of our breadboard products,
that applies over and above the per-board quantity discounts, as follows:

------------------------------------------
$ 500    5%
$1000   10%
$2500   15%
$5000   20%
------------------------------------------

This allows you to combine several of our prototyping products into
one large order for even greater savings.

Note:  The dollar volume discount does not apply to our gold finished items
because of the wide fluctuations in gold prices, so the prices for the
non-gold-plated versions will be used to determine the dollar volume to
find the discount percentage in those cases, even though the prices on the
invoice will be for the gold plated versions that were ordered.  This seems
a bit confusing at first blush, but by exempting the gold from the
equation, the breakpoints can happen at much lower total dollar volumes,
which is better for most customers.  Put simply: we do not discount the
gold.  

(The mini-board has no gold plating whatever, so it is a straight
calculation anyway, but I always have to make this exception clear when
mentioning the dollar volume discount, so it does not come as a surprise
later.)
