FAQ (Frequently Asked Questions) about Macintosh Duo's - part 2
* Last Revision: 04/18/94 *
In October of 1992 Apple released an entirely new kind of computer,
the Macintosh Duo. The Duo, being such a strange beast, has left a
lot of people in confusion. This file summarizes the Duo
information I've collected to date - hopefully it will end some of
the confusion. This information is accurate as of today to the
best of my knowledge, but I make no warranties. I'd appreciate any
corrections or updated information being mailed to me (please be
succinct and patient about a response).
I post updated versions of this FAQ on comp.sys.mac.portables roughly
every two weeks and copies are available via anonymous FTP at
mac.archive.umich.edu and it's mirrors in the archive/mac/util/powerbook
directory.

Expandability/Docks: What do I need a Dock for?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The Duo is a great powerbook - light, fast, small, and powerful.
Additionally it is the only expandable powerbook. With the right
peripheral you can add external monitors, floppy drives, SCSI-2,
accelerators, ethernet, or features that haven't even been thought
of yet.
Below is a list of the Docks currently available, and the features
they offer. MacWorld recently published a table of these docks and
their features (page 34 of MacWorld, Oct. 1993). If you haven't
read it, don't look it up. If you have - be warned there are
numerous mistakes.
Features:
=========
- Floppy: a port for connecting an external floppy drive.
- SCSI(): a port for connecting SCSI devices (HD's, CD drives, etc.).
In parenthesis I've indicated whether the SCSI is Apple's new
30-pin powerbook SCSI (30) or the standard DB-25 SCSI connector (25).
- SCSI-HD: lets you use your SCSI port (above) to connect your
Duo to another Mac as if it were a hard disk on that computer.
Very useful for fast file transfers and installing new
operating systems or other software.
- Serial: a port for connecting external modems, printers, or
using an appletalk connection to other Macs (works only if
your operating system is running)
- ADB: apple desktop bus for connecting external keyboards, mice,
10 key pads, and other input devices.
- RJ-11: a phone jack for the (optional) Duo internal modem.
- Video(): a DB-15 port for connecting external monitors, some
devices offer greater numbers of colors, or access to larger
monitors. The number in parenthesis is the depth of the
video in bits. 1-bit is 2 colors, 2-bit is 4 colors,
4-bit is 16 colors, 8-bit is 256 colors, 16-bit is
thousands of colors, 24-bit is millions of colors.
- PAL: composite video out, lets you connect a European TV as
an external monitor.
- NTSC: composite video out, lets you connect an American TV as
an external monitor.
- Sound: a sound out connector, lets you add external speakers.
- Ethernet: an ethernet card, allowing you to connect at very
fast transfer rates on ethernet networks.
- nu-bus: a nu-bus socket for adding cards for SCSI-2 connections,
second external monitor, faster video, multimedia, etc.
- Open(): my own notation. This means the device does not cover
the Duo's internal ports (in parenthesis), allowing
you to use these as well as whatever the dock offers.
The following is a description of those peripherals I'm
aware of (10 as of today). Following each is a quick summary
of the features offered.
Micro-Docks
===========
1) Apple's Floppy Adapter: For about three months after the release
of the Duo's this was the only dock. It leaves the modem and serial
ports of the duo uncovered, and has a floppy and ADB port. Manufactured
by E-machines, sold by Apple computers, expect about $80.
={Floppy, ADB, Open(Serial, RJ-11)}
[Apple Catalogue (warning: high-prices, if you're in school
contact your EDU source first) 1-800-795-1000]
2) Newer Technologies SCSI Microdock: A great idea. Same form factor as
the Floppy adapter, thus leaving serial and modem ports open. It has a
SCSI and ADB port - only. Supports SCSI slaving of the Duo to a second Mac
for data transfer with the same cable you use to hook up an external SCSI
device. Vice a versa, you can use the SCSI slave cable to hook up external
devices also (the one difference between it and the Lapis version). This
device was developed by Computer Care and is licensed exclusively to Newer
Tech. Runs about $135 at Mac's Place - they seem to have the best price on
it.

[Computer Care, 612-371-0061, FAX 612-371-9342]
3) Newer Technologies Color Microdock: Same form factor as the
Apple floppy adapter it's under 8 ounces and offers 8-bit color
on monitors under 16" in size (4-bit color above that). In addition
to the monitor port, the color microdock adds a sound out and
ADB port. Note this might be the same product "BookView Duo"
from Computer Care, but I have not been able to confirm this.
Retails at $345.
={Video(8-bit), ADB, Open(Serial, RJ-11)}

3.5) Newer Technologies Ethernet Microdock: I see a pattern here.
Newer tech has packaged ethernet into the microdock formfactor.
It's a handy idea for system admins on the run, and runs about
$200.
={Ethernet, ADB, Open(Serial, RJ-11)}
4) Lapis SCSI Dock: Same idea as the Newer tech SCSI microdock, and it beat
'em to market. Form factor identical to the Apple floppy adapter. You can
use SCSI disk mode with a standard 30x25 or 30x50 cable by holding the
control key on startup, rather than using the hard to come by SCSI HD mode
29x50 or 29x25 cables. However you can't use the 29x50 cable to use and
external SCSI device - like you can with the Newer tech version (the only
difference I've heard between the two). Everyone who's talked to me about
it is in love with it. Expect about $160, available at Mac's Place.
={SCSI(30), SCSI-HD, ADB, Open(Serial, RJ-11)}
Mini-Docks
==========
5) Apple's Mini Dock: The standard by which all others are judged.
It connects to the back of the duo, and most closely resembles a
three hole punch. Covering the Duo's internal modem and serial
ports, if offers two serial ports, a RJ-11 port, an ADB port, floppy
port, sound in and out (not stereo), and video out (8-bit up to 16"
monitors). This device is manufactured for Apple by E-Machines.
Note: when you lock one of Kensington's microsavers to the minidock
you can still remove the Duo! That means a thief will have to be
satisfied with your dou, but the dock is safe. No idea if they're
going to fix this bug.

try to buy from your EDU source first) 1-800-795-1000]
6) E-Machine's Powerlink Presenter: One of the first duo docks, the
Presenter is designed for (surprise!) presentations. It does not
cover the duo's phone jack or serial port, and offers a floppy
port, ADB port, sound out, video out (8-bit up to 16" monitors),
and PAL and NTSC video out.
NOTE: The Presenter is substantially larger than the microdocks
but has no support. It hangs on the Powerlatch. Some people
have reported periodic system freezes, and suggest this is due
to the strain on the connection. This is speculation.
={Floppy, Video(8-bit), PAL, NTSC, ADB, Sound, Open(Serial, RJ-11)}

7) E-Machine's Desknet AKA Etherdock: Same form factor as the
Apple's mini dock, the Etherdock (also billed as Desknet) has the
same connections - almost. According to E-Machines specs you loose
the RJ-11 pass through for the internal modem, and gain ethernet.
This means you have to disconnect your Duo to use the internal
modem (you can use an external modem, via the serial port though).
It comes with a 10BaseT ethernet connection, and support 8-bit
video on screens up to 17".

8) RasterOps DuoMate 8: It does not cover the Duo's internal
serial and RJ-11 ports, and adds 8-bit video, NTSC, PAL,
ADB, Floppy and sound out ports. It's shaped a lot like the
E-Machines presenter, but a "foot" has been added to support
the dock. This foot makes the dock a little safer for your
connection, but also makes it the thickest Mini Dock.
It has a 32 bit video data path that is supposed to result
in faster screen refreshes than any other dock (I haven't
tested this claim yet). Expect about $350.

2500 Walsh Ave, Santa Clara, CA 95051 USA]
9) RasterOps DuoMate 16sc: This is the one I bought. It adds
16-bit video on monitors under 16" (8-bit after that) and a
standard DB-25 SCSI connection to the DuoMate 8. Short of the full
dock, this is the only dock to offer better than 8-bit video, and
across the board it's the only one that has a normal SCSI connector
(which means you don't have to buy a whole new set of cables for
your powerbook alone). It supports SCSI-HD mode with a standard
25x25 or 25x50 cable. Note: PAL and NTSC require a special
(not included) adapter. This adapter costs big money (I think
in the $200-300 range). Expect about $545.

Full-Docks
==========
10) Apple's Dock: The works. Simply put, if you want everything
(except dock portability), you want the full Dock. It offers all
the above connections, plus a bay for a hard disk, and slots
for two full nu-bus cards. The video ram is expandable up
to 1 MB (16 bit on 16" monitors) and you can add a FPU to the dock.
This is the only way to add a FPU to non-270c Duo's, and you
only have use of it while the Duo is docked. The full dock
is about the size of a IIci, and you insert the duo into a
bay in the dock, totally enclosing the Duo (unlike the mini
docks) so you cannot use the Duo's internal display and keyboard
with this dock. There is a floppy drive built into the dock
(different from a port for an external floppy drive).
With the thicker 270c, Apple has started selling the full Dock
with a larger hood. You can add this hood to existing
docks for about $70. The new hood has a dust cover over the
powerbook slot so it's easy to spot which docks can use the
270c. The full dock is sold in two configurations: one stripped,
and one with a 230 MB HD, 1 MB VRAM (instead of the standard
512K), and FPU. All of these features can be added if you buy
the stripped configuration. Apple price is about $500.
={Floppy *Drive*, Video(expandable), SCSI(30), ADB, Sound,
nu-bus, Serial, RJ-11}
Full Dock II: (released May 16, 1994)
=============
Apples second generation dock has built in ethernet, fpu,
1 MB of video ram standard, and a 32 Kbyte cache. The cache
and fpu will only acclerate 030 duos that are docked - 040
and 603 Duo's will just ignore them. Other than that it's
expected to have the same form factor and features of the
Full Dock I. A hood upgrade will not be necessary to insert
color Duo's.

nu-bus, Serial, RJ-11, ethernet}
Apples
Coming attractions:
===================
Apple will be releasing a second generation full dock with
built in ethernet. This Dock will also have standard 1 MB
VRAM (8-bit video up to 21"), FPU standard, and a 32 KB
cache. Apple intends to continue to ship the current version
for users who don't want to pay for these enhancements.
RasterOps is working on a third mini dock. All they'll
say is it will have "enhanced video capabilities" - my guess
is 24 bit video. DuoMate 24sc?
Newer Technologies is working on a ethernet mini dock. It'll
come in the "floppy adaptor" form factor and have 10B-T and
and ADB ports.
FAQ about Docks:
================
Why can't I close the lid of my Duo while it's docked to a mini dock?
When you close the Duo's lid, it sends a signal to the Duo telling
it to go to sleep. Mini docks don't support sleep while docked.
As long as the lid is down, it'll keep sending these signals
and you'll keep getting error messages.
How can I have the lid closed while docked to a mini dock?
A neat feature that seems to be added with Duo enabler 1.0.
If you shut down your duo, then dock it, then powerup from
an external keyboard *with the lid closed* you won't get those
error messages. This works with the Apple mini dock and with
my RasterOps 16sc.
--------------------------
Recommended Software:
=====================
* CPU: Connectix PowerBook Utilities. The first commercially available
utilities for the powerbook (and Duo) offer file synchronization,
battery management, and other useful utilities. Note: the
security utility modifies your system *without* letting
you know. If you have a customized system, caution is advised.
The de-installer deletes the added code to your system file.
This bug/feature alone has turned me off on CPU, your mileage
may vary.
* NEP: Norton Essentials for the PowerBook. Similar to CPU, and
what I use. The difference between CPU and NEP is very slight,
and it's just a preference call as to which implementation is
better suited to your tastes. However you do want one or the
other. *Note: Symantec has just announced that they will discontinue
NEP. I'm not throughing mine out, but if you're going to buy one,
I'd pass on it.
* DuoMon: A great freeware application by Mike Blackwell
(m...@cs.cmu.edu) available by ftp at sumex-aim.stanford.edu and
other sources. This utility tells you everything you wanted to
know about your Duo's battery and settings. Indicators show
brightness and contrast settings of the display, clockspeed,
battery id #, battery temperature, current battery usage (useful
for answering question like "How much am I saving by spinning down
my HD, or by using BBedit instead of MS Word?"). You can even
start a graph of power usage that will plot how the battery usage
goes up and down over time. Also, a smaller window can be left
on that shows you current battery level in watts and volts, so
you have an idea how much power is left in your current battery.
* PowerClick: A neat shareware extension by Daniel Segel
(dan...@netcom.com) available by ftp at sumex-aim.stanford.edu
as /info-mac/gui/power-click-101.hqx on mac.archive.umich.edu
as /mac/system.extensions/cdev/powerclick1.0.1.cpt.hqx.
Did you know that the mouse buttons on your Duo are
wired separately? Not true for other powerbooks, this feature
offers the potential of having the two buttons do different
functions. Daniel's code lets you set either button to do a single
click, click lock, double click, or nothing. Setting the bottom
button to nothing is a very useful option for those of us who use
our Duo's in our lap, say lying back in the sofa. I don't know how
many times the weight of my Duo has accidentally clicked the lower
button. (Note: not to be confused with "Powerclicks 2.0" - with an
"s" - which is an entirely different program)
* Disinfectant: the internets answer to the latest virus. Duo users tend
to rely on telecom and slaving other CPU's floppies, so they're more likely
to get a virus than the average user. Also, those without docks can be
crippled by a bug chewing on their system - so they're more vulnerable as
well.
That said, you should have Disinfectant on all you machines. John Norstrad
keeps the latest release (available via ftp) at ftp.acns.nwu.edu in
/pub/disinfectant. Disinfectant is freeware.
*** latest release is Disinfectant 3.5 ***
*Duo Extension Picker: I haven't tried this one myself, but have gotten
a lot of mail asking about it. It's a two part program (extension and
control panel) written by Alan Steremberg (al...@engin.umich.edu) that
detects whether or not (and to what) your Duo is docked at startup. Then
loads a set of extensions you choose. This way you can have your Duo
load the CD init and MacTCP when you're docked to the full dock, but
not load 'em when you're using your mini dock, or going dock-less. Kool
idea, and available at sumex-aim.stanford.edu.
(this part still under construction, please send any recommendations you
think would be valuable)
Recommended Hardware:
=====================
* APS SCSI Boy: If you have a Dock (Micro, Mini, or Full) that uses an
Apple HDI-30 pin SCSI port - you want this. It's a small metal adapter
that inserts into your HDI-30 SCSI port and converts it to a standard
DB-25 SCSI port. That means for $29, you can use all your existing
cables on your powerbook. It's also a lifesaver if you're on site,
forgot a powerbook specific cable, and need to scrounge.

* Targus PowerPac: padded Duo case. It's hard to find a case you like,
even worse if you own the Duo. This is the one I settled on. It measures
14" x 11" x 2.5" with an outer pocket that measures 13" x 9" x 2". The Duo
fit's in the main compartment *sideways* - an included divider leaves
exactly enough room for a floppy adapter and floppy drive (although I
usually use the space for the power adapter and a paperback novel). The
nylon case comes in five colors (blue, teal, gray, purple, and black), and
there is a leather version too. It runs $39 at MacWarehouse, $99 if
you're into leather.

* MagentaCase/MagentaCase Lite for the Duo: case *designed* for the Duo.
Magenta systems make a nice powerbook case, better still they just released
a version designed specifically for the Duo. The cases are described as
MagentaCase *for the Duo* - not to be confused with there MagentaCase. The
case (black) has a central pocket, document, and accessory pocket. The
lite version (black or burgundy) has only one pocket. They run $55 and
$22, direct. Disclaimer - I've never seen/used one.

5109 Holly Ridge Drive, Suite 209, Raleigh NC, 27612-3146]
* Imagewriter (Appletalk) Cable: An essential. This $11 cable is
available at any computer supply store or mail order house. It has
a DIN-8 connection on both sides. Plugging one end into your Duo's
serial port and another into the serial (printer or modem) port of
another Mac lets you Appletalk between them -to transfer files or
use the other computers floppy drive. If you have a "Dockless" Duo
you can't survive without it.
* Kensington Microsaver security cable: Useful. This cable attaches to all
Duo docks (including the micro docks). By locking the cable to the
"security slot" in the dock and to a table leg you can discourage your Duo
from walking off (most docks will not let you remove the Duo when the cable
is attached). Will not prevent a dedicated thief (nothing will) but will
discourage crimes of opportunity. Sold by MacConnection (among others) for
about $40.

[Kensington 415-572-2700]
* Replacement trackballs: OK, this ones a luxury. But if you want
to add a little personality to your Duo, you can replace the
Apple trackball with a couple options. The first is a 11 mm
marble, they're kind of hard to find but people have reported they
work great. The second option is a day glow ball made just for
the Duo's. They're available in four colors (the green, yellow,
orange, and violet of the apple logo) for $10 ea. or $20 for all four
from APS tech. They're cute, I haven't tried 'em yet.

6131 Deramus, PO Box 4987, Kansas City, MO, 64120-0087]
* LightningScan Portable: portable hand scanner. This hand scanner is
battery operated, 400 dpi, 8-bit gray scale, and has OCR. The device
connect via a serial port, where as most connect via SCSI. That means this
is one of the few scanners you can use with a Duo without a Dock. You get
30 minutes of scanning per charge, but realize that that's 30 minutes of
actual scanning. You don't use juice while the device is just turned on.
I've got a lot of e-mail raving about this, and am thinking about getting
one myself - but I have no first hand knowledge of it. With all the
necessary software for scanning and OCR, it runs $399 through MacWarehouse.

1720 Oak St., PO Box 3013, Lakewood NJ, 08701-9917]
* Powerbook Floptical. Iomega is releasing a $399 battery operated 21 MB
floptical drive. It's going to be sold exclusively through the Apple
catalog. It's a SCSI device and also reads floppy disks. Teamed with a
Duo SCSI adapter it makes a killer option for Duo users (PB 100 users
should also take note).
* Duo Battery Charger. Excerpt from add, (I have no personal experience):
"Lind Electronic Design is now shipping the SuperCharger II for the PowerBook
Duo NiMH batteries. The SuperCharger II is specifically designed to charge
the Duo batteries as quickly as possible with no time consuming trickle
required. This unit will also condition the battery to prevent and correct
the loss of capacity due to 'memory effect'. Lind model SBC-2 available
now for $149.95 (visa m/c accepted)" - note NiMH batteries are not supposed
to have any "memory effect", I have no idea why they are selling a conditioner
feature.

* PowerPlate 4x: Duo Battery Plate (4x the power of type I NiMH): Technoggin
announced a 3.6 lb lead acid battery that fits under the bottom of the Duo
and has a life time of 4x NiMH I or 3x NiMH II Duo batteries. It's supposed
to cost $299.95 and will begin shipping this quarter. Note: VST also expects
to ship a version of this battery called the ThinkPak Duo - no details.
