=head1 DESCRIPTION

Emulates an Acorn BBC Micro 6502 Tube second processor. You'll need to find your own language ROM to load and it's only been tested with BBC Basic II.


INTERFACE

See the Acme::6502 manpage. Acme::6502::Tube is an Acme::6502 instance that has been initialised with a skeleton Tube OS.


CONFIGURATION AND ENVIRONMENT




Acme::6502 requires no configuration files or environment variables.


DEPENDENCIES

Acme::6502


INCOMPATIBILITIES

None reported.


BUGS AND LIMITATIONS

Tube OS emulation is very minimal - just enough to run BBC Basic II. If you extend it let me know.

I've included the HCCS Forth ROM in the distribution (I used to work for HCCS and did a little work on the Forth ROM - although Joe Brown wrote it). Unfortunately it doesn't currently work with Acme::6502::Tube - so that'll have to wait for another day.

Once the Forth ROM works I'll use it to write some tests.

Please report any bugs or feature requests to bug-acme-6502@rt.cpan.org, or through the web interface at http://rt.cpan.org.
