\section{ABOUT THIS BOOK}

{\advance\baselineskip-1pt
\advance\parskip-2pt
In 1988 I started this project with a table entry in the 1955 CRC¨
Chemistry \& Physics Handbook comparing LPG to other common¨
fuels. Then I found out that it was quite popular in various¨
industrial equipment, and wondered -- if it's so good, why isn't¨
it used for passenger cars? The only answers I can come up with¨
are inertia, ignorance, and greed. 

It's a short-term -- 20 years or so -- solution. I'm not¨
dismissing arguments regarding automobiles and their destructive¨
nature; I merely attempt to address what you \& I can do, by¨
ourselves for ourselves, today. 

Positive aspects of the automobile-as-transport-device aspects¨
are often overlooked; long-distance ``road trips'' are an¨
intrinsic part of our various and peculiar North American¨
cultures and one I will not give up willingly. Each of my 8000+¨
mile road trips have been powerful and enlightening things, and¨
now I don't have to pee in the environmental pool to do them.

In urban areas cars are ridiculuous, and if cities would stop¨
relying on them as income sources (tickets, parking fines, etc;¨
you'd be shocked how much income your city derives from cars) and¨
built usable intra-urban transport systems, and at the state¨
level (I only say this because I can't imagine municipalities¨
working together cooperatively) there were usable inter-urban¨
systems, I think things would be very different. 

\smallskip

This book has many problems. It's too skimpy on content, and¨
needs to be a textbook. It needs LPG component and supplier data.¨
I totally forgot fuel mileage (it's 10\% less MPG than gasoline).¨
But I had to make the project reasonable, and cut it off at this¨
point to get it done at all. I'll consider myself lucky if I get¨
complaints that it wasn't enough information to complete the job¨
(by assuming it {\it was} enough to get started).

This book was typeset using \TeX, Donald Knuth's gargantuan¨
public domain mathematical typesetting system, on a DOS 386¨
computer and DeskJet 500 printer, on 60 lb. matte coated paper,¨
hand pasted onto 8.5  $\times$ 11 paper to make copy masters.¨
Photos were taken on the usual lousy pocket camera, ``screened''¨
using the FINE PHOTO setting on a Canon Laser Copier, then cut¨
and glue-sticked into place. Books are xeroxed and hand stapled.

\centerline{\bf The Fido/FidoNet\trademark\ Bulletin Board System¨
Software}

\tenpointsanserif

Fido/FidoNet is a software package for DOS based Personal¨
Computers that contains a complete Bulletin Board System (BBS)¨
plus a fully automatic Electronic Mail system. 

Fido is the best-known Bulletin Board system in the world because¨
of its flexibility, reliability, and features; FidoNet is the¨
software that defined the FidoNet protocol now in use around the¨
planet. The worlds largest privately-owned computer network¨
(10,000 nodes, April 1991) is based upon the FidoNet¨
communications protocol.

Fido\trademark\ Bulletin Board System:

{\parskip=0pt\parindent=12pt\obeylines
\item{\blob}Absolute security
\item{\blob}Caller access controls
\item{\blob}Language/graphical interfaces
\item{\blob}200 message \& file areas
\item{\blob}Email and message commands
\item{\blob}Error-free down/uploads
}

Fido is a full\dash featured Computer Bulletin Board System.¨
Callers, commands, message and file areas can all have separate¨
privilege levels and Locks \& Keys applied to them; these let you¨
limit callers' access to any part of the Fido system to fit your¨
needs.

\item{\blob}Wide Area Networking
\item{\blob}Completely automatic
\item{\blob}Error-free transfers
\item{\blob}Time-of-day scheduling
\item{\blob}Auto message routing
}

FidoNet is an automatic ``store\dash and\dash forward'' mail¨
system that transfers mail and files with all other 
FidoNet-comatible systems. It is completely integrated with Fido,¨
and transparent in operation, and if you don't use it, you won't¨
even know it's there.

Requires: DOS 2.00 up, 256K memory, hard disk recommended, plus¨
any reasonably modern ``AT-command'' type modem.
