- How The Circuit Works
- ~~~~~~~~~~~~~~~~~~~~~
- I designed a simple passive circuit that does the job quite well. Here is
- the
- schematic diagram.
-
- +------+ T1 +------+
- o-----| R1 |-----o------o--------(| |)-----| C1 |-----o-----o
- +------+ +| -| (| |) +------+ |

- jack +---+ +---+ (| |) +---+ line
- -| +| (| |) |
- o------------------o------o--------(| |)------------------o-----o
-
- C1-.22 uF, 200V
- D1,D2- 1N4148 switching diode
- R1-620 ohm, 1/4W
- T1- 8 ohm to 500 ohm audio transformer, Mouser part 42TL001
- VR1-300V MOV, Mouser part 570-V300LA4
-
- VR1 is a 300V surge protector to guard against transient high voltages.
- Capacitor C1 couples the phone line to transformer T1, blocking the phone
- line's DC voltage but allowing the AC audio signal to pass. The transformer
- matches the impedance of the phone line to the impedance of the headphone
- jack.
-
- Diodes D1 and D2 provide clipping for additional ringing voltage protection
- (note their polarity markings in the schematic). They will clip any signal
- above 7 volts. Resistor R1 drops the volume of the audio signal from the Mac
- to a reasonable level. The end result is a circuit that isolates the Mac
- from dangerous phone line voltages and provides a good quality audio link to
- the phone line.
-
- Building and Using the Circut
- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- This simple circuit is easy to build (if you're handy with electronics). I
- personally prefer to solder the circuit together. A length of shielded audio
- cable with a 1/8 inch mono plug on one end should be connected to the audio
- input end of the circuit. A standard RJ11 phone jack should be connected to
- the phone line end of the circuit. Although this circuit will protect
- against dangerous phone line voltages, it is best to disconnect it when not
- in use. You just don't want to risk anything bad happening to your brand new
- Quadra 900, right?
-
- Once you have an audio link between your Mac and the phone line, the
- applications are limitless. Use HyperCard's built-in DTMF dialing to dial for
- you, or build a memory dialer stack. Talk to people with Macintalk. Play
- your favorite Ren and Stimpy sounds for your friends. Play a ringback tone
- to "transfer" people to an "extension". Build and use a set of synthesized
- MF tones. Try to trick COCOT's with synthesized busy and reorder signals.
-
- But Wait, There Is More...
- ~~~~~~~~~~~~~~~~~~~~~~~~~~
- So you say you don't own a Macintosh? That is ok, because the circuit can be
- used with other devices besides your Mac. You can use it with the 8 ohm
- headphone output from tape recorders, radios, scanners, etc. You could also
- probably use it with any other computer as long as you had the proper audio
- D/A hardware and software to create sounds.
-
- All parts are available from Mouser Electronics. Call 800-346-6873 for a
- free catalog.

- SECTION VI: MAC HACK TIDBITS
- ----------------------------
-
- 26. How do I copy a read-only file?
-
- Many utilities allow you to copy read-only files, including StuffIt,
- CompactPro, etc.
-
- 27. Where can i get the latest version of macpgp and the source code?
-
- Telnet to net-dist.mit.edu and login as 'getpgp'. You will have to answer
- four short questions to get the name of the file it is in(the name changes
- every half hour). Then FTP there and go to the specified directory. The
- current version is MACPGP2.6.2. You should also get the README files as the
- interface barely follows the Macintosh Interface Guidelines.
-
- 28. How can I convert a Read Only text file?
-
- Read/Write Convertors v1.0--I run a BBS with about 5500 files online. I'd say
- on average I put up about 15-20 new files a day. This equates to ALOT of File
- Descriptions. To cut down on the work of Writing File Decriptions, I like to
- just grab first or second sentence in the READ ME file in an Arhive which
- usually explains what the program is and/or does. Nothing bugs me more than
- when the Author converts the READ ME to one of those damn READ ONLYs which
- not only prevent you from odifying the file but also prevent you from
- selecting and copying text within the file. No copying and no electing means
- no snagging that oh so valuable first sentance that cuts down on File
- Descripting. Fortunatley my woes have been mended. Micheal Terry of Oakfield,
- New York put together a couple of Drag&Drop apps which will convert a file
- from one of thos Annoying READ ONLYS, or, if you wish to annoy me, TO on of
- thos Annoying Read Onlys. They work great and he only wants a buck a piece
- for them. http://vsl.cnet.com Search: 'convertor'
-
- 29. How can I Disable Extension Disabling on my Mac?
-
- Probably the oldest, easiest, and single most commonly used hack on any
- system, is holding down the Shift-Key to disable Extensions. By doing this
- ALOT of Security or Access related programs can be by-passed. If you don't
- want your System to be vulnerable to this Shift-Key Extension disabling heres
- what you can do: Use ResEdit or some other Resource editor and open your
- System File. Delete the 'dbex' resource. Tadow! You've just disabled
- Extension Disabling. By the way, the 'dbex' extension is used for no other
- purpose (that I know of) so no harm will come to your system. This little
- hack is courtesy of Scott Kevill <skevill@tartarus.uwa.edu.au>, and Aussie
- commonly found on alt.hackintosh.
-
- 30. Is there a way to disable the Power-down Button
-
- Does that "feature" of being able to shut down your Mac by pressing the power
- button annoy you too? I never understood why it was important to have a
- keyboard shortcut for a function that I might use at most once a day. And now
- the System 7.5 update brings this wonderful behaviour to all Macs! But here's
- how you can turn it off:
-
- 1. Open a copy of the "System 7.5 Update" file with ResEdit.
- 2. Look for the "gpch" resource with ID 16. At offset D22 hex, you will see
-
- the words BF8C 4267; change these to 0002 600A.
- 3. Save your changes and exchange the original System 7.5 Update in your
- System Folder with the patched one.
- 4. Restart. Press the power key. Enjoy the fact that nothing happens.
-
- As usual with this sort of patch, keep a Disk Tools disk handy to boot from,
- in case you stuff something up.
-
- 31. Is there a way to turn off zoomrects in System 7?
-
- The first thing you need to do is open up the finder with RedEdit. Then you
- open the code resource, then look for Code ID 4, (this does need to be
- decompressed). Then Select Find offset and look for the code 0078, this
- should take you to this line:
-
- 48E7 1F38 594F 2FOF
-
- Then select 4 bytes (48E7 1F38), Replace them with these codes:
-
- 6000 00E6
-
- Save the copy of Finder and quit ResEdit, then Make the copy of the Finder
- (the real thing) Put the old one in a safe place incase it screwed up. Now
- just reboot the machine, and open up a Window.
-
- 32. Outro
-
- Well thats as good as it gets for this one. I hope you found it informative.
- I'd like to give a shout out to AX1P for conceiveiving the FAQ, and to
- Observer, Filbert, and everyone else for their NO Bullshit information.
-
- For the next issue I'm expecting some further incites on FirstClass and an
- extensive tutorial on EvE protection, so look out for the next release. See
- ya online.
