The first Bally Astrocade multicart was created by Ward Shrake in 2001.
This is the documentation area. If you're interested in seeing additional pictures of the multicart,
then visit the multicart picture area.
Ward has given his blessing to use this information to create other
multicarts as long as, he says, "folks credit my work, if they use all of or part of the design" (see
the release letter below for additional information about this).

This zipped download includes two Word Documents, two PDF documents and a text document; use the
pdf documents, not the Word documents (which are included in case any changes need to be made). Two
documents are the same information sorted into two different ways: alphabetically and alphabetically
sorted by extra RAM needed or not. The last document shows which dipswitch settings are still
available. |
