VERSION

This document describes Acme::6502::Tube version 0.76

SYNOPSIS

    use Acme::6502::Tube;

    my $cpu = Acme::6502::Tube->new();

    # Load BBC Basic
    $cpu->load_rom('BASIC2.rom', 0x8000);

    # Init registers
    $cpu->set_pc(0x8000);
    $cpu->set_a(0x01);
    $cpu->set_s(0xFF);
    $cpu->set_p(0x22);

    # Run
    $cpu->run(2000_000) while 1;

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 Acme::6502. "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>.
