Introduction & Hardware Needed
|
Being
able to communicate between the Z88 and the Desktop has always been the
main attraction of having the Z88. What is the point of not being able
to share files between the PC or Mac computers?
The software for the Desktop (PC or Mac) is downloadable from the Wiki.
Users have different requiments.
|
|
These are:-
- to get data off their old EPROM cards, a 'once off' exercise and then get rid of the Z88 altogether.
- to use the Z88 as it was in the 80's, transferring files as a backup to their destop
- to use the laterst version of OZ, get faster transfer speeds and enjoy the latest refinements of the Z88.
The following hardware and software is needed.

USB to Serial Adapter or Lead
|
Two typs of adapters

Whatever you decide you will need:
- PC AT 9/9 way Serial Cable
If your computer has a standard 9D serial port - (or a and Standard Serial Cable extender and Rakewell's Z88 Serial Link)
- USB/serial device, with Rakewell's Z88 Serial Link (with standard serial cable extender if needed) or PC AT 9/9 way Serial Cable If the computer only has a USB connector.
|
Option 1 - Z88 9/9 way Serial Cable
|
![](../images/z88_to_pc_cable.jpg)
At first sight this looks like a 9 way extension cable. It isn't. Although the plugs and sockets are the same, the |
|
connections are different to the now standard connections.
If you are handy with a soldering iron, you can modify existing cables to use. Again, details are on the Wiki.
The Z88 will not connect to the Desktop with a straight-through cable.
|
Option 2 - Using Z88 Serial Link
|

Z88
Serial Link is a lightweight alternative to using the Z88 PC Serial
Cable. Often when using a laptop, the extra bulk that the cable
gives is unwelcome.It can be used both with a Mac or PC.
|
|
The Z88
Serial Link fits in-between the Z88 and the USB Serial Adapter. This
changes the connections allowing the Z88 to be used with Eazylink or
any other Z88 communications software.

|
Using Z88's Imp/Exp Popdown
|
Using both the software on the Desktop, the connecting cables and the Z88's own Imp/Exp popdown program, files may be transferred each way. It is painfully slow and not 100% reliable, |
|
but it works on a good day.
Commands are made on both the Z88 and the Desktop, useful for four handed operators. |
Using Eazylink with the Z88

Eazylink2 is available free on the web for your desktop.It is downloaded from the Z88 wiki

![Eazy Flash ROM](../images/EazyFlash2.jpg)
Using a 32K EPROM card to run the Eazylink popdown is faster and is controlled at the Desktop end.
If you have either a
![](../images/pc_link_rom.jpg)
|
|
or a
![](../images/mac_rom.jpg)
32K EPROM, these maybe erased and used as an Eazy / Flash Application card.
We can do that for you on the condition that if the EPROM doesn't erase for any reason, we will return it to you.
If you haven't got either, they may be purchased.

Upgrading to OZ 4.7.1
|
Eazylink here allows fast transfers at 38,400 baud and are crc checked.
Use either the 512K/512K Flash/RAM card, or
the 1M Flash and 1M RAM cards configuration. See OZ Upgrade
