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 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. 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!

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:
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:).
Each address book entry is limited to 32k.
Each note book page is limited to 32k.
The following devices are availabke under dos:
CON: - Displays text on the screen.
AUX: - Not connected to rs-232 or i/r
PRN: - Not connected to rs-232 or i/r
Note: no com ports or lpt ports are defined.
Config.sys Commands:
On the following pages configuration commands are listed.
Each command must be on a separate line on the config.sys. The commands can
be in upper or lower case. The config.sys and autoexec.bat file must be on
the B:\ drive in order to work.
BREAK - Stop program execution
BREAK - Turns on and off the ability to stop program execution at a non-i/o
point.
Default: OFF
Ex: BREAK=ON
Note: This wil not benefit the Zoomer due to it's lack of a keyboard.
BUFFERS - Sets # of internal buffers
BUFFERS - Sets the number of internal data buffers.
Default: 2
Ex: BUFFERS=20
Note: The benefit of buffers is minimal insystems that do nothave physical
disk drives.
DEVICE - Allows for new device drivers
DEVICE - Installs a new device driver in6o ROM DOS.
Ex: DEVICE=A:SDPCHAR.SYS
FCBS - CPM style file handles
FCBS - Specifies the number of File Control Blocks open at one time.
Default: 4,0
Max: 255
Ex: FCBS=10,20
Note: Most dos applications do not use these file handles. These file
handles are for backward compatibility to old dos applications.
FILES - Max # of files open
FILES - Sets the maximum number of files that can be open at one time on the
system.
Default: 8
Max: 255
Ex: FILES=20
LASTDRIVE - Sets last drive available
LASTDRIVE - Sets the maximum number of drives available.
Default: E
Max: Z
Ex: LASTDRIVE=F
SHELL - Use a different Command Processor
SHELL - Allows the selection of an alternate command processor other than the
default COMMAND.COM. Parameters /P make permanent, /E:size changes
environment size [size in bytes].
Default: The COMMAND.COM must be on the boot device.
Ex: SHELL=A:\COMMAND.COM /P
NEWFILE - Chain to Another File
This allows for a second file with config.sys commands to be prodessed.
Ex: NEWFILE=MYCONF.SYS
The config.sys is processed until the NEWFILE command, then the myconfig.sys
is processed.
Zoomer DOS Config & Commands
Here's a list of the commands available for the Zoomer. Please note that
Datalight provided the ROM-DOS v3.31 which is included in the Zoomer.
For users that are used to using MS-DOS, ROM-DOS is nearly identical. Keep
in mind that only commands for v3.3 are supported on the Zoomer.
Thanks to the support of Datalight the following information is available.
Let me know if you find any additional commands that are not documented.

Zoomer Hardware
The following is a description of the Zoomer's hardware. This discussion is
very technical. It is drawn from the Tandy Service Manual p/n 25-3100.
THE FOLLOWING IS MY BEST GUESS BASED UPON READING THE SCHEMATICS. PLEASE USE
THIS INFORMATION WITH CAUTION!
Major Components:
CPU: NEC V20 equivalent p/n fPD 95130GD-5ML. This chip includes the
interrupt controller, timers, infrared, and LCD controller. Also includes
memory management unit (similar to EMS). The data bus is 8 bits and the
address bus is 20 bits (1mb address space). Also has a custom timing
generator for all the above components.
Bus Controller: p/n MBCG25173-5104 Controls the Touch Panel, Sound Interface,
PCMCIA Card Interface, and RS-232 Interface. Also provides real time clock.
RS-232 Driver: p/n MAX223CAI-T Converts power from 3v to 5v.
Sound DAC: p/n uPD65043GF-U01-3B8 It is an 8 bit DAC known to be drivable at
8khz.
PCMCIA Card Interface circuit: This interface only supports 8 bit cards not
16 bit cards. It is limited to 50milliaperes and 5 volts. PCMCIA type II
cards are supported.

GEOS.INI TIPS
The tips and tricks that follow are unsupported and/or undocumented. The use
of these modifications may result in data loss. USE THESE TECHNIQUES AT YOUR
OWN RISK!!! These techniques will improve the useability and efficiency of
your Zoomer.
Enjoy!
Remember to reset the Zoomer in order for your changes to go into effect.
PS: Don't forget to look in the Geoworks forum on AOL for many enhancements
to the GEOS.INI.
File Linking [link] 2x Speed!
[link] Section - File Linking -Twice the Speed
The [link] section is for the file linking function:
name = system name
port = 0 - rs232
2 - infrared
baudRate = 12 - 9600 bps
6 - 19200 bps
3 - 38400 bps (doesn't work)
drives = add and delete the drives based on what you want to be available on
the other PC.
{
A:
B:
C:
SYS:
}
Note you must have your ram card installed before you file link. If you do
not, the ram card will not be seeen by the other PC. Just disconnect and then
reconnect.
Here is an example:
[link]
name = zoomer
port = 0
baudRate = 6
drives =
{
A:
B:
C:
SYS:
}
The above setup will allow you file link at 19200 and allow you to access al
the Zoomer drives from your PC. Don't forget to change your PC's preferences,
connect baud rate to 19200 bps.
Then you can enjoy twice the speed!
Run 15 Apps!
Heresbhow to run many more applications at the same time.
Change the line under [system]:
maxsystemHeapSpace = 31000
to
maxSystemHeapSpace = 65000
Just be careful not to run out of ram or the system will reboot. We need an
app that tells how much ram is available.
To add more ram to Geoworks, change the line under [system]:
memory = { }
to
memory = {
disk.geo
}
This will allow Geoworks to swap to the B: drive. So make sure you have ram
card (sram or flash, it does not matter) and have deleted as much as possible
from the B: drive.
Speed up Screen and Buttons!
The [motifoptions] has a parameter that controls the delay between each
action of the user interface(eachclick with the pen)
It is measured in 1/60ths of a second.
Default: gagetRepeatDelay = 18
Recommended: 6 to 10 depending on your sensitivitry.
Remember, the lower the number, the faster the response. If the number is
very low, it is easy to have characters repeated unexpectedly.
Smaller Scroll Bar - More Screen Space!
Almost all Geoworks applications usecscroll bars. By changing [motifoptions]
scrol arrow size,(size in pixels)
Default: scroll arrow size = 8
Recommend: 6 or 7
Remember, the smaller the number, the more precise you need to be with the
stylus.
Smaller Font - More Screen Space
The font size for the Geoworks display under the [system]:
Default: fontsize = 10
Recommended: 9
Supported sizes: 9, 10, 12, 18
The smaller the number, the smaller.the font.
Non-Blinking Cursor
To make the cursor not blink, add the line in [input]:
cursor blink = false
