Foreword
During a two week leave in February 2007, I got a little bored.
So I decided to make use of my skills in circuit developing, microcontroller programming
and printed circuit board design in order to refresh my attainments.
Luckily, I had some left over Flash-EEPROMs in my hobbyist-box which, for a long time, I
wanted to put to use.
As a Lynx fanatic, I stumbled upon several demo and games on the Internet, but with
burning EEPROMs being rather time consuming, I impulsively made the decision to build a
FlashCard for the Lynx.
With this FlashCard, I want to give a tool to demo and game developers, which hopefully
will help to increase the homebrew-scene around the Lynx, at least a little. I would be very
glad to see some of the projects, even those already started, being completed with the
help of the FlashCard.
After two years of developing this card, I'm looking forward to using my Lynx only for
playing, for quite some time.

Terms Of Use
All hints for the correct use of the terminal program refer to HTerm 0.81beta. If you are
working with another version, you have to adjust the settings appropriately.
For HTerm, you have to make the following adjustment from the default setting:
Set “Newline“ to “CR + LF“ (See “Short Introduction to HTerm“ on Page 15 for more
details.)
The handling of the menu and all pop ups of the FlashCard are explained in reference to
the English version.
This manual is only valid for "board 1" FlashCards.
(PCB variants 1.2xx and 1.3xx)

Important: ESD
Electrostatic Discharge (ESD) is an unwelcome phenomenon in electronics.
Describing ESD and its effects in detail would go beyond the scope of this manual. There
are other sources referring to this issue; Wikipedia being one of them.
It is very important that you do NOT touch the FlashCard when you are electrostatically
charged.
You should always discharge yourself of any static prior to touching the FlashCard. You
can do this by simply touching anything made of metal.
It is best not to touch the components or contacts of your FlashCard.
Important: Use of FlashCard with Lynx I & Lynx II
The FlashCard has been designed for use with a Lynx II.
You can also use the FlashCard with a Lynx I. However, due to the enclosed cartridge slot
of the Lynx I, there is a danger of damaging the Card by plugging and unplugging it, as
well as by the opening and closing of the cartridge door with the Card inserted.
I do not recommend the use of the FlashCard in an unmodified Lynx 1!
However, if you insist on using the FlashCard with your Lynx I, you should remove the door
permanently, prior to inserting the FlashCard. Note: No documentation will be provided to
assist you in removing the door.
Naturally, every change you make to your Lynx is done at your own risk.
It is always a good idea to think before you position your screwdriver. ;-)
Important: Miscellaneous
Use the Lynx FlashCard at your own risk. The creators of the FlashCard assume no
liability or responsibility due to damage. No warranty is included with this product or the
documentation. The FlashCard is not intended for use in any way that would violate the
law.
