F/+HINT1
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.

Electron User Guide Errata
-----------------------------------------------------------------------------
For your information the example on page 34 should read:
VDU 19,2,RND(3)+1,0,0,0
The example on page 59 should read:
10 A$ = "J"
20 PRINT A$; A$; A$
30 PRINT A$; A$; A$
40 PRINT A$' A$' A$
> RUN
The example on page 60 should read:
10 X = 6
20 A$ = "J"
30 PRINT X,X,X' A$, A$, A$
> RUN
On page 95 the following statements should read:
40 VDU 23,1,0;0;0;0'
VDU 23,1,1;0;0;0
On page 100 the FX phrases on lines 1 and 9 should be replaced by OSWORD.
On page 114 please read Mode 7 as Mode 6 - due the fact that Mode 7 is not
available on the Electron.

*FX/Osbyte features not documented in the BBC Micro User Guide
-----------------------------------------------------------------------------
&0D (13)
Two undocumented parameters may be supplied in X to disable events:
X = 7 disable RS423 receive error event
X = 8 disable service/network error event
&0E (14)
As above, two undocumented parameters may be supplied in X to enable events:
X = 7 enable RS423 receive error event
X = 8 enable service/network error event
Events are explained on p465 of the User Guide.
&76 (117)
This call returns the VDU status byte (which contains various status flags)
in the X register.
BIT 0 - set if VDU2 sent, cleared by VDU3
BIT 2 - set if PAGED MODE ON, cleared if PAGED MODE OFF
BIT 3 - set if software scrolling, cleared if hardware scrolling
Software scrolling is used when text windows have been defined whereas
hardware scrolls are used when the whole screen scrolls.
BIT 5 - set when cursors joined by VDU5
BIT 7 - set if VDU disabled
&76 (118)
Returns with the carry bit if the CTRL key is pressed, and with the Negative
bit set if the SHIFT key is pressed. Machine code routines may branch on
these conditions. This feature is invalid when called from a Second
Processor.
&7B (123)
This call is used by the User Print Routine to indicate to the MOS that it
has finished its task. (CF *FX 5.3 command). This feature should not
normally be called from a Second Processor.
&8A (138)
This call has been expanded to allow a character to be inserted into any
buffer. X must contain the buffer number, and Y the character to be
inserted. A list of buffer numbers appears with *FX 21 on p428 of the User
Guide.
&8D (141)
This command is exactly equivalent to the *ROM command.
&98 (152)
This call examines a buffer. The buffer number must be in X, and the call
returns as follows:
Carry bit set if buffer empty
Carry bit clear indicates character(s) present in buffer.
Note that no character has been removed from the buffer.
&99 (153)
The call inserts a character into an INPUT buffer handling the interrupt
character, and generating an escape condition if necessary.
Valid only for X = 0 or 1
Y must contain character to be inserted
&9C (156)
Change 6850 control register. The 6859 register is altered to: (Old value
AND Y) EOR X. (See User Guide page 438).
Refer to the 6850 Data Sheet for details of the 6850 control register.
&9E (158) / &9F (159)
These calls respectively read and write to the Speech Processor chip. Refer
to the Speech System User Guide.
&E9 (233)
As for &E7 (see User Guide page 441) but affects the system 6522. The system
6522 is used extensively in the normal operation of the machine and
consequently this call should be used with extreme care.
