The Macintosh PowerBook Fax/Data Modem is Apple's internal modem card for the first PowerBooks. It handles data at 300, 1200 and 2400 bit/s and sends faxes at up to 9600 bit/s, and it fits inside the PowerBook 100, PowerBook 140 and PowerBook 170.[1] It was standard in the 170 and optional in the 140.[2] The modem sends faxes but cannot receive them, a limit of the hardware.[3]
Apple sold two versions: M0970LL/A for the United States, Canada and Japan, and M0980/A for Europe, Australia and some South American countries.[4] Apple's Getting Started manual printed M0980 as the US part number; the price list's M0970 is correct.[5] The international versions of Apple's PowerBook modems have a mini-DIN 8 socket in place of the RJ-11 phone jack, each built for its country's DAA.[6] Apple would not sell the international version in the US, and would not recommend using either version abroad with a plug adapter because neither was certified for the other's networks.[7]

Which PowerBooks take it
[edit | edit source]The Fax/Data Modem fits the PowerBook 140, 145, 145B and 170, with which it shipped, and also the PowerBook 150, PowerBook 160, PowerBook 165, 165c, PowerBook 180 and 180c.[9] The PowerBook 100 takes it on its own connector.[10] The later Apple Express Modem does not fit the 100, 140, 145, 145B, 150 or 170.[9]
Internal modems by model
[edit | edit source]| PowerBook | Modem |
|---|---|
| PowerBook 100, 140, 145, 145B, 170 | Apple Fax/Data Modem (2400 bit/s data, 9600 bit/s fax) |
| 145B (US, some units) | Global Village PowerPort Bronze fax modem (2400 bit/s data, 9600 bit/s fax); some early 145Bs had no modem |
| PowerBook 150 | None fitted; shipped with Apple's modem patch software, needed for a third-party modem |
| PowerBook 160, 165c, 180, 180c | Apple Express Modem (14.4 kbit/s) |
| Duo 200 and 2300 series | Apple Express Modem for Duo (14.4 kbit/s) |
| 500 series (international) | Apple Express Modem II (14.4 kbit/s) |
| 500 series (US) | Global Village PowerPort Mercury for the PowerBook 500 Series (19.2 kbit/s) |
| PowerBook 5300, 190 | No internal modem; PC Card modems in the PC Card slot |
The table follows Apple's article of October 1996.[6] Apple's support pages also call these cards the PowerBook internal modem.[11] The Express Modem for the Duo 210 and 230 does not fit the 100-series or 500-series PowerBooks.[9] For the PC Card modems used in the 190 and 5300, see Apple PowerBook PCMCIA Expansion Module.
Installing
[edit | edit source]PowerBook 140, 145, 145B and 170
[edit | edit source]The modem card is an option on the 140, 145 and 145B and standard on the 170.[12]
- Remove the main battery, the I/O door and the top case. Wear an earthed wrist strap: the board's CMOS parts are easily damaged by static.
- Pinch the release tabs and push out the modem port cover.
- Plug the modem card's connector into motherboard connector J8.
- Fit the two mounting screws.
- Stick the FCC modem label inside the I/O door, lined up with the modem port, and the DOC label inside the door, lined up with the HDI-30 SCSI port.[12]
PowerBook 100
[edit | edit source]On the PowerBook 100, remove the backup batteries, the main battery, the display assembly and the keyboard first. The lithium backup cells can explode if mishandled.[10]
- Push the metal prongs towards the back of the computer and lift the modem shield out of the bottom cover.
- Lift the modem connector cover out of the bottom cover.
- Hold the modem with its connector J1 facing down, directly over motherboard connector J9, and press it down until it locks on the two standoffs.
- Refit the modem shield, making sure it does not stick out into the battery cavity, and refit the connector cover.
- Apply the DOC and FCC labels to the left of the modem connector.
To remove the modem, release the locking tabs of the two standoffs with needle-nose pliers and lift it off.[10]
Modem connector (PowerBook 140 and 170)
[edit | edit source]| Pin | Signal | Pin | Signal |
|---|---|---|---|
| 1 | MODEM.N5 (−5 V, not used by Apple's modem) | 11 | MS.ENABLE |
| 2 | MODEM.PWR | 12 | /RTS |
| 3 | GND | 13 | RESET |
| 4 | /MODEM.BUSY | 14 | /CTS |
| 5 | US5V (+5 V ±5 %) | 15 | /MODEM.INSERT |
| 6 | RxD | 16 | GND |
| 7 | /RI.DETECT | 17 | GND |
| 8 | TxD | 18 | MODEM.5V |
| 9 | MODEM.SOUND | 19 | /DCD |
| 10 | /DTR | 20 | MODEM.5V |
The Power Manager switches MODEM.5V on pins 18 and 20, and the modem asserts /RI.DETECT on an incoming ring to wake a sleeping PowerBook. A fitted card holds /MODEM.INSERT low.[2] The developer note says Apple's modem does not use the −5 V on pin 1, although Apple's specification sheet lists −5 V among the modem's supplies.[2][8] An internal modem card is connected to channel A, the modem port; the hardware could run it through either serial port, but the firmware supports only the modem port.[2]
Software
[edit | edit source]The last software made only for the Fax/Data Modem was FAX Sender 1.0.3. Apple's later supported software for it was Express Modem 1.5.5, and Telecom 2.3.2 works with it under System 7.1 or later.[13] A Read Me on the Fax Sender 1.0.3 disk mentions modem firmware version 1.2, but that ROM was never produced.[14] In 1993 Apple knew of no third-party fax software that supported the modem.[15] If faxes are slow to prepare, set Fax Page Setup image quality to Standard instead of Fine.[16]
To check which modem is fitted, send ATI4 from a terminal program such as ZTerm. The Fax/Data Modem replies with "data/send FAX"; an Express Modem replies "APPLE EXPRESS MODEM".[13] The modem has no Hayes guard time. It drops into command mode on a BREAK, or on the strings +++AT…<CR> or +++<CR>AT…<CR>, recognised by the characters alone. Apple lists only those forms; the Hayes form, +++ on its own between one-second pauses, is not among them.[11]
Faults
[edit | edit source]| Symptom | Apple's steps, in order |
|---|---|
| Internal modem options missing from the control panel | Reseat the modem card; check the System is 7.0.1 or later; replace the modem card; replace the motherboard |
| Modem does not respond to AT commands | Check the baud rate and data format in the software; check the phone cord; reseat the card; check the System version; replace the modem card |
| Garbage characters on screen | As above, then replace the daughterboard and the motherboard |
| Modem interferes with system sound | Reseat the card; replace the modem board; replace the interconnect card; replace the motherboard |
| Modem does not answer incoming calls | If the computer is asleep, check Wake On Ring is selected; check the phone cord; replace the modem card; replace the motherboard |
| No modem sound | Check the volume is above 0; replace the modem card; replace the interconnect card; replace the motherboard |
| Connects but will not communicate | Error correction is on by default; if the remote modem does not use it, type &Q0 to turn it off |
