diy programming board?

Hello!
My basic stamp came in today! Woop! However, I didn't buy a
programming board. Is the basic stamp similar to the oopic in that it
has a built in RS232 level shifter built in? AHHH!! Wait, wait,
wait. I think I found it. All I need to do is build that happy
little circuit shown in the schematic called "PC - to - BS2p40-IC
connection"! That's it?!? :-)
One more question.. does the basic stamp have it's own built in power
regulator?
Thanks a ton!!

places, works like a charm.
It does have a regulator built in but DONT use it to power much. Regulator
has something like 50mA max capability. Refer to the parallax website for
experiments to do etc.

Basic stamp?
In that case, the programming boards is useful equipment for
beginners since the Stamp can be programmed in a socket and have
access to I/O pins as well. A serial cable is connected from your PC
to the BS (Pin1-4). Study the book of this connection and look for
the two 0,1 uF caps. They have a special function. Your are
referring to a schematic: PC to BS2p. This is not a schematic to use
when you shall send the program from the PC to stamp, but used if a
PC-program (e.g. Visual basic) shall communicate with a stamp.
Remember: Port 16 (Pin 1-4) is a true serial connection using
12volt. I/O-port 0-15 is also capable of sending serial information,
but only at 0-5 volt. Don't connect P0-15 from your Basic Stamp
directly to the PC. If you use a RS232 driver (like MAX 323) you can
power up the TTL signal (0-5V) from the Basic Stamp to 12V level.
Take care of your Basic Stamp. Go to the store and get the extra
equipment as well a serial cable. Read the book. Don't try the hard
app-kit first.
Study the different Basic Stamp models in the book: BS1 BS2 and on,
so you don't get confused when you see a code from a BS2p, but only
have a BS2. (I was confused for a long time)

on-chip. Be aware it uses the +12 from the
PC 232 TX wire to drive the +12 RX signal
back to the PC.
Yes, it does have an on-chip regulator. It
is limited to 50 mA, but means you can feed
the chip 6 volts to 9 volts on its 'Vin' pin,
and it won't fry.
Perhaps you can go as high as 12 volts, I
havn't wanted to risk it. I assume the
regulator would go into thermal shutdown
to protect itself if you used too high a
voltage. Note 24 volts probably would
destroy it.
