The Z88 Does Not Work
If the Z88 does not switch the display on when you press both Shift keys, or if it flashes on, but then goes off again there are several things that you can do.
If The Z88 Has Worked Before
|
If not, do a Soft Reset. (Continue to Hard Reset). |
If the Z88 hasn't worked
Check batteries If they are all right, do a Hard Reset
If the Z88 still hasn't worked, you should remove all the RAM, ROM and EPROM Cards from the Z88 and try another Hard Reset.
If it still isn't working, things are looking desperate here. Remove all batteries and allow the Z88 to stop completely for 15 minutes, then replace the batteries and try another Hard Reset.
At this point just check you done the following:-
Checked all the AA size batteries. They should be at 1.5v each
Removed all the external cards i.e. RAM FLASH and EPROMs
Given the Z88 a Hard Reset, by opening the Card Flap, pressing the RESET switch twice and closing the Card Flap again..
Turned the contrast knob fully one way and then the other, to see if anything appears on the screen at all.
If the Z88 doesn't power up here then it is faulty.
Not quite a faulty Z88
If it does work, you should try replacing the Cards back into the Z88 one at a time.
Do a Hard Reset between times so that you can establish which card is causing the fault.
Printer fails to work
Check that the:-
Printer is `ON-LINE' and the `ready' light is on.
Cable is connecting properly at both ends.
Cable is not damaged.
If you are in PipeDream:-
Has the square cursor disappeared?
Yes - The Z88 wants to send text but can't. Press . You should see ESCAPE appear at the top left-hand side of the screen.
No - You have not issued the PO command.
If you have typed or loaded a new file into the Printer Editor did you remember to:-
updated the printer driver
double checked the Printer DIP setttings on the printer
remembered
FU (File Update) in the Printer Editor
If this still fails, then see Serial Port Lock Up
Serial Port lock up
If your Printer, Modem, PC Link or anything that is plugged into the Serial Port simply stops working, your Serial Port may have locked up.
The cure for this is to give your Z88 a Soft Reset which will reset the communication buffer and registers that tell it what to do.
Reset
Hard Reset
A Hard Reset is used when starting a Z88 from scratch or as a `last resort' to get a crashed Z88 working again.
A Hard Reset will
clear all files in RAM
reset the time. date and your personal setup options
run a BOOT.CLI file (if you have one) in an EPROM pack.
To do a Hard Reset, you should OPEN the card slot, have all your RAM and program cards you wish to use plugged in the slots.
Press the reset button twice, then shut the card slot cover.
You should see HARD RESET... appear in the top left-hand corner of the screen.
After doing a Hard Reset
If you have any RAM packs fitted, you should remember to set the Panel (S) Default Device to :RAM.1 and change the Device in the Filer (F) to :RAM.1. These will be set to the internal ram :RAM.0 after a reset.
The Time and Date (T) also need to be set.
Soft Reset
This can also be selected with PURGE in INDEX.
WARNING Before doing a Soft Reset make sure there are NO FILES in your:RAM.- device. See Bug - :RAM.
When you do a soft reset your Z88, OZ (the operating system) tries to gain control again. If it is successful, you will loose all your suspended applications, but still have your files intact
If the soft reset is not successful, - you may get a Hard Reset.
To do a soft reset make sure that the card flap is CLOSED, press the reset button (labelled 2 in photo) once. You should see SOFT RESET appear in the top left-hand corner of the screen.
If you have any RAM packs fitted, you should remember to set the Panel (S) Default Device to :RAM.1 and change the Device in the Filer (F) to :RAM.1. These will be set to the internal ram :RAM.0 after a reset.
After a successful Soft Reset, you should do a Hard Reset as soon as possible. This is because a soft reset is designed to get you out of trouble rather than completely resetting the Z88. It is possible for the gremlin that caused your Z88 to go wrong is still there, waiting to strike again. Doing a Hard Reset puts the Z88 into a known state. A reset one.
You must backup your files between a Soft Reset and a Hard Reset. See Backing up Files.
