Casio Z-7000, Tandy Z-PDA, AST Gridpad 2390
The Casio Z-7000, XL7000, Tandy Z-PDA and AST Gridpad 2390 are all the same
machine, the Zoomer. The XL-7000 does not include AOL, or other US specific
documents.

The machine was engineered by Casio, Palm Computing, Datalight and Geoworks.
Casio designed the hardware and ROM BIOS. Datalight provided it's ROM-DOS
v3.31. Palm Computing provided most of the applications that run on the
Zoomer as well as the handwriting recognition (PalmPrint). Geoworks provided
Geoworks v2.0 and also provides development software for the Zoomer in it's
SDK.

Hats off to all for a job well done!

Remember, all accesories for the Zoomer are interchangeable!

Handwriting Recognition
The following information is courtesy of Palm Computing, developer of the
handwriting recognition (PalmPrint) for the Zoomer.

Verticle lines should be verticle, horizontal lines should be horizontal,
straight lines should be straight, and curved lines shouldn't be squiggly!
Words to write by!

Try the writing grid of the keyboard as a training tool. It will show you
what it "thinks" the letter looks like, and helps you form the letters
consistently.

Don't write too slowly, try to write at a normal speed. Hesitation will cause
the handwiting recognizer to try to process what you've written before you're
ready.

Consciously write each individual character instead of words. Try spelling
each word silently in your head while you write until your pace and letter
formation deliver successful recognition.

Serifs on 'l' and 'g' will help eliminate ambiguities with '1'/'I' and 's',
respectively.

If the dot over an 'i' or a 'j' is to the left of vertical, you will get
weird results. The dot will either be taken as a period or will be grouped
with the previous character. For example, if the previous character is an
'l', you may get a result of 'il', when 'li' was intended.

PalmPrint is designed to accommodate post-dotting and crossing, but if you're
having trouble try to dot the 'i' and cross the 't' when you write them, as
opposed to going back and dotting and crossing at the end of the word.

Make the downstroke of an 'r' without curves, to eliminate confusion with a
'v'. Better yet, make your 'r' with a single, curved upstroke, leaving out
the vertical downstroke. This may seem odd at first.

Put a slash through 'Z' and 'z' to distinguish it from a '2'. Slashed 'z'
is currently slightly biased towards an upper case 'Z'.

To guarantee zero, as opposed to 'O', slash it.

Writing 't' and 'h' too close (experiment!) together will yield an 'A'. It
is further aggravated by the vertical stroke of the 't' or the 'h' being
slanted.

Avoid gaps and overlaps between strokes of letters. Disjoint 'B' will be
'13', and disjoint 'R' will be '12'.

'e' is often interpreted as '2'. Make the horizontal line, then the 'c', all
as one stroke.

'4' is often interpreted as 'k', 'y' or 'x'.

'k', 'y' and 'x' are often interpreted as '4'. Form these letters more
carefully. See the manual and try the writing grid.

To write a space, draw an underline and then draw right over it.

Left-handers: Be careful to keep letters vertical. Draw horizontal strokes
from right to left. Form letters, particularly 'b' and 'd', in single
strokes if possible.

When writing multiple lines, the highest stroke of a line must be lower than
the lowest stroke of the line above. Overlaps can cause erroneous results.

Asterisks work a lot better if you use the stroke order and direction
documented in the manual.

Use the keyboard to insert stubborn punctuation.

Handwriting Recognition Stroke Limit

When entering text using handwriting recognition, there is a maximum of 60
strokes buffered by the recognizer. This means that you can only write about
5-10 words in ink (depending on how many strokes you use per letter) before
allowing the handwriting recognizer convert the ink to text. Any strokes
made over the 60-stroke limit will be discarded. This doesn't imply any
limit to the number of words total in a particular page, title, etc.,
simply how much you can write before allowing the recognizer to process it.

Marking Text
The folkowing information was provided by Palm Computing.

Marking Text:

Second-click - marks the word where the cursor is.
Third-click - marks the segment or entire line
Fourth-click - marks current paragraph
Fifth-click - marks the entire text on the page, even if it is not shown.

You can also use the stylus to select text by dragging the stylus down and/or
across the text you want to select. Remembervto wait a second after putting
the stylus on the screen, otherwise, you will be using the handwriting
recognition.

After you have marked text, you can copy it by using the sketch tools (camera
icon).

ROM Application Bugs
DATEBOOK ANOMALY WARNING

In the Date Book Application:
If you go from the sketch page of an event to a 6-month, month, or week
view, the Page menu will show the Page-Send/-Receive choices inappropriately
active. Any attempt to do a Page-Send or Receive will apply to the most
recently visited Sketch page, but will leave machine in an unstable state,
with data-loss crash possible.

Do not attempt to do Page-Send or Receive from these views.

If you crash from this state or another unstable state, you must do a Soft
reset per the instructions in your User Guide. You should NOT lose any data.

Note: There have been problems reported regarding repeating alarms extending
to a new year. Until further notice, do not set alarms to extend past the
end of each year. Reported behavior includes redundantly repeating alarms
and difficulty in purging information from the Datebook.

CLOCK RESET SURPRISE

There is a bug in the World Clock which may manifest itself in the Zoomer
crashes under certain circumstances.

If the "destination" is set to a time zone other than your home time zone,
AND the system clock is set to "destination", AND the machine is re-booted
for any reason, upon restart, the system clock will be set to the
"destination" time zone. That is, the time that was originally the time at
the destination becomes the system clock time AND the "home" time. This is
due to the fact that the World Clock settings are saved in a State file which
is erased each time the system is rebooted. This will be changed in future
designs of the World Clock.

Workaround1: To fix this condition, you must first set the desired "home"
city in the World Clock, then tap the Launcher and choose Utilities>Time and
Date. Change time and date to correct the system clock.

Workaround2: After you set the World Clock correctly, switch to another
application. Go into the File Manager and locate the state file for the
World Clock in B:[INTERNAL]\GEOWORKS\PRIVDATA\STATE.

Copy the file "wclock app (transparent)" to B:\[INTERNAL] or some other
backup area, eg. a PCMCIA card. Then, whenever you Reset your PDA, copy this
file back into the the ...STATE folder. When you next open the World Clock
it will have the saved settings.

PCMCIA Usage Notes
The following information is courtesy of Palm Computing (edited for size).

RAM CARD TYPES
1. SRAM - Smaller ram card (128k to 2mb) that requires a battery to retain
the data written to them. This card does not draw aditional power from the
Zoomer. Thie battery should be replaced every year. Most cards have a
capacitor in them to retain the data for about 10 minutes. Sram cards are
faster than flash cards.

2. FLASH - Larger ram card (2mb to 40mb) that draws high power from the
Zoomer to read/write data. If you are doing alot of reading/writing(ex:
backup), use the AC power supply. The flash card does not have or require a
battery. It does retain data indefinitely, however there is a limit of over
300,000 writes to a specific area. Some cards recommend the use of a
leveling utility to even the wear on the card. The Zoomer does not have a
wear utility.

PCMCIA CARD WARNINGS

1. Flash cards -- Writing to the card could cause what seems to be a sudden
low battery condition which is not immediately detected by the power manager,
but may cause problems in writing files to the flash card. Flash cards may
cause the PDA's power to switch off automatically when available battery
power drops below a certain level. Power may switch off before the
low-battery power message appears on the display. This is done to protect
the contents of the PDA. Some uses of PCMCIA cards may cause the power of
the PDA's batteries to run down relatively quickly.

Crashed boot sectors have been reported on some PCMCIA memory cards due to
undetected low battery conditions. Some PCMCIA cards may draw power faster
than the power detector recognizes. Use of the PCMCIA card in a low-battery
state has caused corruption of the PCMCIA boot sector in SOME cases. There
are very few reported cases of this. SunDisk, maker of this type of card,
has said that only a small number of these cards were distributed by them
which were subject to this problem.

Symptoms: Your Zoomer suddenly shuts down without warning, provocation, or
expected timeout.

You must replace the main batteries in the Zoomer PRIOR to powering up again!
Corrupted boot sectors have been successfully recoverable.

In the unlikely event you are using a SunDisk flash memory card and
experience the problem of an unrecognizable card, contact a Casio or Tandy
service center, or call SunDisk Technical Support (408-562-3400) for
assistance.

2. PCMCIA memory cards must be treated cautiously to avoid loss of data.
Just as you would not remove a hard drive or floppy while running an
application, you must give the Zoomer the opportunity to close cached or open
applications before removing the card.

If you are only using your PCMCIA memory card as a file backup there are no
special considerations. You may insert or remove the card at any time.

If you open data files on the PCMCIA card from a application, please observe
the following:
- Turn on your Zoomer BEFORE inserting or removing the card.
- If you insert the card before turning on the Zoomer the file structure on
it may not be recognized. The Zoomer will automatically scan the card at
time of insertion.
- To remove the card: Turn on Zoomer. Unseat the card and immediately
re-seat it in the slot. Observe the warnings. You will be prompted to close
the open and cached applications prior to removing the card. This process
may take 30 seconds or more. When complete, you will see an alert box
telling you that you may remove the card safely.

Failure to remove cards in this manner may cause unrecoverable loss of data,
mostly due to corruption of the file headers.

Other Considerations:
- If you have a data file which will not open by double-tapping, try opening
the application first, then Switch Document to the desired data file.

-After creating a mirrored directory structure on the PCMCIA card, toggle the
PCMCIA Lock switch in order for GEOS to merge the drives/directories
together. Example: Create C:\GEOWORKS\WORLD\GAMES and copy a file into it.
It will not show up on the File Manager until after toggling the Lock
switch. Creating the mirrored directory structure will slow the Zoomer due to
the additional time required to scan the PCMCIA card during the launching of
each application. PCMCIA cards which are only used for storage, and do not
have a parallel file structure to the one on the PDA are NOT automatically
accessed, and so do not cause any delay in operations.

!! Warning: If you are launching an application which uses program
libraries on the PCMCIA memory card, removing the memory card while the
program is running may cause your PDA to crash.

- Do NOT create copies of the same data file in parallel file structures on
both the PCMCIA card and the internal drive. For example: If you create a
\GEOWORKS\DOCUMENT structure on your PCMCIA card, then COPY your "Favorite
Restaurants" Notebook to it, then delete one of them. There have been 1 or 2
cases of both copies getting deleted (though we have NOT reproduced it
here.). It works fine to copy files to ANOTHER directory, say \BACKUP or to
use a different structure on the memory card.

- In the File Manager, Filenames with underlines indicates that the
file is located on another drive.

Generally, for best performance, keep programs and libraries on the
B:[internal] drive, and use your C: card for data files and backup.

PCMCIA Ram Card Formatting
In some instances, the Zoomer will format a PCMCIA card to the wrong size,
usually 128k.

If this occurs, from File Manager, run a:sdisk.exe (this can be done on any
Zoomer). Sdisk will prompt you whether or not to format the card. Press thecA
button to format.

Then the card should be setup correctly.

PCMCIA Cards
All PCMCIA cards for the Zoomer are 5 volt and 8 bit in ATA fat format. The
Zoomer does not support ffs (Microsoft Flash File Service). The following
cards work with the Zoomer:

SRAM Cards:
Apple Newton 1mb SRAM p/n 649-0013A
Simple Technologies 1mb SRAM
ACE 1mb SRAM. ACE Technologies [408] 428-9722

Flash Cards:
All Sundisk SDP-5 and SDP-5A 5 volt flash cards. Sundisk (800) 535-2943

AST:
G44-1410 1.8mb SunDisk flash card
G44-1412 2.6mb SunDisk flash card
G44-1415 5.2mb SunDisk flash card

HP 128 RAM card
HP 5mb Flash card

Maxtor MobileMax flash cards (2,4,8,12,16 and 20mb) Maxtor (800) 462-9867

Modems:
AMT Starcard 2400 modem
AMT Starcard 14.4k modem (714) 375-0306

Pagers:

Motorola EMBARC Newscard - Now just news broadcast - Motorola dropped
paging/e-mail from EMBARC.

Remember, SRAM cards require a separate battery to power the card. It must
be replaced periodically or you lose the data.\(about once a year). Most
cards will work for about 10 minutes or longer without a battery.

Also, SRAM is faster than Flash.

The following cards do NOT work with the Zoomer:

Megahertz 14.4 gold modem
Megahertz XJack 14400
Apple Newton Flash cards (1 and 2mb)
Intel Flash Cards

AOL Tips
America Online is provided with the Zoomer. This version is limited to
2400bps by AOL even though 9600 is show under setup.

To delete your screen alias, delete B:\GEOWORKS\PRIVDATA\AOL\USERDB.VM. This
wil require you to setup AOL again.

AOL provides limited access to Zoomers:
PDA, Mail, Stock Quotes, News, and Support.

Save money, compose mail off-line and then call in and send it.

There is a limit of 8k for each mail message or text screen. Downloaded
files are limited only to available disk space.

You can use uucoder.geo to create uuencoded files for E-mail. Just keep in
mind that they are still limited to 8k.

Penright!
Penright is available for the Zoomer! Penright is another operaing system for
the Zoomer by AT&T. Many verticle market applications are designed with
Penright.

Penright comes installed on a Sundisk ram card. It allows easy switching
from Geoworks to Penright and vice versa.

Casio is offering Penright, Zoomer, 1.8mb flash card, and a serial cable for
$569.00, 1.8mb flash card w/Penright $220.00 or Penright on disk for $65.00.

Zoomer Drives and Files
The Zoomer contains the following drives:

A: - ROM boot drive.
B: - RAM storage drive (350k) Alternate boot disk if you have CONFIG.SYS,
AUTOEXEC.BAT and COMMAND.COM.
C: - RAM PCMCIA storage card.
SYS: - ROM Geoworks applications - Only accessible while in Geoworks. Only
visible when using the Zoomer File Manager.

Boot Sequence:

1. If B: has CONFIG.SYS, the system will attempt to boot on B: Remember, you
must have AUTOEXEC.BAT and COMMAND.COM in order to complete the boot. If you
boot from B:, add SHELL=A:\COMMAND.COM /P to your config.sys to save 23k!
WARNING - If you do not have the above files on B:, the system is
unrecoverable and you must do a hard boot.

2. Boot from A:

Note: By booting from drive B: you can customize your CONFIG.SYS or
AUTOEXEC.BAT. An example is the installation of Stacker or the Enhanced
Zoomer

Geoworks Directory Merge:

1. The SYS: and C: directories and files are accessible to Geoworks when
they occupy the same directory structure. Only \GEOWORKS and its
subdirectories are overlaid.

2. The precedence order is B: ,C:,SYS:. Where B: files are always seen.

In File Manager all files that are underlined are on other drives (SYS: or
C:).

The following devices are availabke under dos:
CON: - Displays text on the screen.

Note: no com ports or lpt ports are defined.

File System Information:
