Hi All,
This manual was withdrawn by Abacus earlier this year, but the good news is that the author, Rich Garber, has now made it available on his website.

The price is the same as Abacus sold it for ($10) and the download can be purchased here : http://www.allaboardrails.com/at.htm - it's a .pdf file.

It may be worthwhile if this thread could be made into a 'sticky', so as to make it more visible, please.
