- Q. I want to connect another IDE hard disc to my Risc PC. What links must I set?
- A. Assuming you are fitting a second hard disc similar to the one already fitted
- (a Conner CFS series), you need to make sure that the (not)A/C link is fitted
- to both drives and that the M/S link is only fitted to the drive connected
- directly to the motherboard. (not)C/D should be left in the state it was in at
- shipping.

- Serial Ports, Printers and Modems: Part 2
- -----------------------------------------
- Unlike IBM PC compatibles, Acorn machines default to using the DSR line to flag
- readiness to transmit, and require the presence of the DCD signal. On machines
- fitted with the 82710 or 82711 serial controllers and the Risc PC, it is possible
- to change which signals are used for flagging in software, using the
- SWI"OS_SerialOp",0 command. Thus an IBM compatible cable may be used; the option
- to reprogram the serial port in this manner is currently provided by some serial
- communications software. If you have a suitable machine and prefer to use an
- over-the-counter IBM standard cable rather than resort to making your own, check
- with the supplier of your communications software that there is an option to
- reprogram the serial controller.
-
- It is possible to transfer data between a 32-bit Acorn computer and an 8 bit BBC
- Model B / Master series via the Serial Port; the wiring diagram for the
- appropriate cable is presented below.
-
- On the transmitting system (assumed to be the Model B / Master), issue:
-
- *FX8,4
- *FX3,1
-
- The first call sets the transmission rate to 1200 baud, and the second selects
- the serial port as the output device.
-
- From BASIC on the receiving machine, (assumed to be a 32 bit Acorn machine),
- issue:
-
- SYS"OS_SerialOp",1,0
- SYS"OS_SerialOp",5,4
- *FX2,1
-
- The first command configures the parity and word size: note that the Model B
- defaults to one stop bit per word, whereas the 32 bit range defaults to two. The
- second sets the receive rate to 1200 baud, and the third sets standard input to
- be via the serial port.
-
- Performing a LIST on a BASIC program stored in the BBC's RAM, or a *TYPE on a
- plain text file stored on disc, will cause the program or text to be loaded into
- whichever RISC OS application has the caret on the receiving machine.
-
- To terminate communication, issue
-
- *FX3,0
- *FX2,0
-
- on both machines; the receiving machine should terminate communication first.

- Updates to the RISC OS Applications Disc
- ----------------------------------------
-
- Following on from the release of !Printers 1.22, Acorn has released another disc
- containing improved versions of applications originally supplied with RISC OS
- 3.1. The disc contains:
-
- !Alarm, version 2.61
- !Calc, version 0.53
- !ChangeFSI, version 0.95
- !Chars, version 1.17
- !PrintEdit, version 0.38
- !T1ToFont, version 1.26
- 3Dupgrade
-
- The applications have been changed in various ways. As well as feature
- enhancements, known problems with the applications have also been fixed. The
- applications now automatically contain the 3D icons and templates supplied as
- part of !NewLook, so there is no need to use the !NewLook templates.
-
- !ChangeFSI
-
- ChangeFSI has been updated to support further image formats, and the formats
- previously supported have been updated.
-
- !PrintEdit
-
- PrintEdit has been updated to allow support for the new options available within
- the Printer Definition files supplied with !Printers 1.22.
-
- !T1ToFont
-
- T1ToFont has been updated in various ways:
-
- If you have a Type 1 file but no corresponding AFM file, you can produce a usable
- font by simply leaving the 'AFM file' field blank. The resulting font will lack
- kerning information, so do use the AFM file if you have it.
-
- Most alphabetic fonts should convert successfully with the Encoding field set to
- "Acorn Extended Latin". Some symbol fonts have their own private encoding; for
- these it is recommended that you select "As specified in Type 1 file" from the
- Encoding menu. This causes the font's internal encoding to be used, ensuring
- that the glyphs are placed at the correct character codes. The encoding is also
- deposited in a file named "Encoding" in the font's directory, where the font
- manager and printer drivers can make use of it.
-
- 3DUpgrade
-
- The directory 3DUpgrade contains two BASIC programs, one called 2D and the second
- called 3D. The programs can be used to set the correct bit in CMOS RAM to ensure
- the templates and icons are shown in 3D or 2D depending on your choice.
-
- !Alarm, !Chars and !Calc have had minor fixes made to them.
-
- The disc containing this upgrade suite should be available from all Acorn dealers.
