The Machine Binary-Block is a binary-block extension for the 9830 providing some machine-level support functions and commands. The MBB is generally loaded from a tape BIN file, although it could be incorporated as a ROM card if one wished, with some minor modifications to the code to move some variables out of the binary-block.

The MBB currently provides the following:

BlockScan BASIC Program

Included in the tape image with MBB is the BlockScan program. BlockScan scans the 9830 memory looking for installed binary-blocks, and prints the block linking tables and information. This includes all the keywords (commands, functions, statements) in those binary-blocks.
