This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

 6502 Second Processor Utility ROM


 The 6502 Second Processor Utility is a 6.5K ROM image
which can be loaded into sideways RAM in the BBC B or B+ I/O
processor. It has been designed to work with the DNFS and
Acorn 6502 second processor. It is may not work as specified
with a 6502 second processor from any other manufacturer.
Although some of the commands it provides can only be used
with a second processor, most of the commands can also be
used with the second processor switched off or not
connected.

 A few of the commands may be recognized by Telesoftware
users and are second processor versions of sideways RAM
programs previously broadcast on Telesoftware. The commands
are all used by typing an asterisk followed by a command
word. A help menu lists the commands and can be displayed by
typing: *HELP 6502 (or *H.6.)

 Some of the commands use arguments. An argument is
optional if enclosed in parentheses ( ) and compulsory if
not. Many of the compulsory arguments are optionally ON or
OFF, but then either ON or OFF must be typed. All the
commands can be abbreviated but a minimum of three
characters must be used and followed with a full stop. The
commands may be typed in either upper or lower case and may
be prefixed with an optional X (or x) if a command clashes
with another command in a ROM in a higher priority socket.

 When this ROM image is used the character ignored by the
printer is changed from linefeed to the null character and
the interlace will be off in all modes except mode 7.

 Memory locations &900 to &92F in the I/O processor are
used by the commands *AUTOSAVE, *ECHO and *LISTO. For this
reason these locations should not be used by any other
software. This area of memory is normally used on the BBC B
as either an extended envelope storage area, an RS423 output
buffer or as a cassette output buffer.

 The Commands:

*AUTOSAVE <filename>
*NOAUTO

 Autosave is used to automatically save onto disc a BASIC
program from either the I/O processor or the second
processor every three minutes. This utility should only be
used when editing a BASIC program and is disabled by either
typing *NOAUTO or by pressing Break. I/O processor memory
from &900 to &91F is used by Autosave and must not be used
by any other software while the utility is active.

*ECHO ON/OFF

 The command *ECHO ON enables the Acorn speech processor in
a BBC B or BBC B+ computer to produce a talking keyboard.
The computer must have the Acorn speech upgrade fitted
because the program does not work with any other speech
system. It uses I/O processor memory from &920 to &927 and
will work along side other systems, such as Superior
Software SPEECH!, as long as the Acorn system is available
as well.
 You can include *ECHO ON in a BASIC program and each key
press will then be heard as well as seen. *ECHO OFF or
pressing Break will switch the utility off. *ECHO can be
used with either Wordwise Plus or View (and probably other
programs) to produce a talking word processor. Type *ECHO ON
in the menu mode of either word processor.

*HIBASIC

 This command selects Hi-BASIC if the second processor is
active and the Hi-BASIC ROM is available.

*LISTO ON/OFF (0-7)

 *LISTO ON enables an assembly language formatter which can
be also be used with BASIC files. Using the optional number
(0-7) will enable the equivalent BASIC LISTO command as
well. For example, *LISTO ON 1 has the same effect as typing
*LISTO ON and then LISTO 1.
 The formatter should only be used to make a program
listing easier to read and understand. It remains active
until *LISTO OFF is used.
 When this utility is active files can be loaded into
memory and saved or listed, but must not be edited or run.
If *POUND ON has been used, type *POUND OFF before typing
*LISTO ON. *LISTO automatically uses the pound correction
when printing. This routine is a second processor compatible
version of *ALIST from the LX80 Toolkit and uses I/O
processor memory from &928 to &92F.

*LOBASIC

 This command selects BASIC 2 if the BASIC 2 ROM is
available.

*NAMEROMS

 Nameroms is used to produce a list of the paged ROMs,
their hexadecimal socket numbers, and type (either service S
or language L). For example:

>*NAMEROMS

F (S) 6502 Second Processor Utilities
E (L) BASIC
D (S) DFS,NET
C (S) TELETEXT
2 (L) WORDWISE-PLUS
1 (L) BASIC
0 (L) BASIC

*NEWBASIC

If BASIC 4 is available in either ROM or sideways RAM this
command will select BASIC 4. BASIC 4 will only be selected
on the BBC B if the second processor is active.

*NOBASIC

If you do not need to use a language in the second processor
type *NOBASIC and the > prompt will be replaced with a *
prompt. You can now load and run machine code programs in
the area of memory previously occupied by a language.

*OLDBASIC

This command selects BASIC 1 if the BASIC 1 ROM is
available.

*POUND ON/OFF

 When using an Epson printer with the United Kingdom
character set selected the ` character is printed as ' and
the # character as `. *POUND ON will cause these characters
to be printed correctly. Your printer must have the UK
character set selected before typing *POUND ON. *POUND OFF
will turn this utility off.
 *POUND ON cannot be used if *LISTO is being used. This is
not a problem since *LISTO automatically accesses the pound
correction.

*TUBE ON/OFF

Before this command can be used the 6502 second processor
must be switched on and enabled by pressing Ctrl-Break. The
second processor can then be disabled by either typing
*TUBE OFF or including the command in a program. The I/O
processor will then become available with the highest
priority BASIC language selected. The character set will
remain exploded after using *TUBE OFF but can be imploded
with *FX20.
 Typing *TUBE ON will continue the task in the second
processor where it left off when *TUBE OFF was used.
Pressing Break will also give access to the second processor
without continuing the previous task. *TUBE ON can only be
used after using *TUBE OFF - it cannot be used to select the
second processor immediately after switching it on.

*WWPLUS

 WWplus is used to define the red function keys for use
with the Wordwise word processor. You can type *WWPLUS
either before typing *WORDWISE or in the Wordwise menu. If
you type Y in reply to the question "Are you using Wordwise?
(Y/N)" the function keys will be defined with the following
Wordwise commands which can be added to the text in the edit
mode by typing <CTRL> <SHIFT> <f-key>.

<f0> LX80 Near Letter Quality.
<f1> LX80 Draft mode.
<f2> LX80 Paper out sensor on.
<f3> LX80 Paper out sensor off.
<f4> Emphasized print on.
<f5> Emphasized print off.
<f6> Underline on.
<f7> Underline off.
<f8) Italics on.
<f9> Italics off.

 The embedded commands generated by the function keys can
be used to print text on a computer not equiped with the
utility ROM. The file WWFKEYS can be used with the
Telesoftware program KPRINT to print out the new function
key definitions.

*SUPPRESS (<hex. number>)

 *SUPPRESS is used to disable paged ROMs until Break is
pressed. If no argument is specified the utility ROM itself
is disabled. For example *SUP. 2 will disable the ROM in
socket 2, *SUP. without an argument will disable the 6502
Second Processor Utility ROM. A list of the socket numbers
and their contents can be obtained by typing *NAMEROMS.

*RESET BBC

 *RESET BBC resets the computer to its switch-on state.
User memory is cleared but sideways RAM is unaffected.
*RESET BBC can be abreviated to RES. BBC, the argument BBC
must be typed in full to help avoid an inadvertent reset.
This utility is not available when the second processor is
switched on.

*RFSCAT

 The ROM filing system (RFS) accesses data stored in paged
ROMs in the same way that the cassette filing system (CFS)
accesses data on tape except that saving or writing to ROM
is not available.
 The RFS can be selected and catalogued by typing *RFSCAT.
All the CFS commands except SAVE, *SAVE, OPENOUT, BPUT# and
PRINT# are available.
 The utility ROM uses the RFS to store a demonstration
program which can be chained into either the I/O processor
or the second processor. For Example:

>*RFS.
