Making
a Z88 to PC Lead
![[image of mismatching plugs]](../images/wrong_plug.gif)
When Cambridge advertised their Z88 - PC Link we all thought
it was a lot of money to pay for the cable. I made up a cable
and discovered it was not as easy as I first thought.
Even now, people are still making the same mistake as I did back then.
I invite you to
- not to buy a standard 9 way to 9 way cable. It may physically fit, but the wire connections are different. It will not work, or
- not burn your fingers
with a soldering iron or
- can't fit the plug into the Z88 after fitting the cover or
- use the wrong
circuit diagram to wire up the lead. There are several of them shown on different web sites.
PLEASE save yourself all
this hassle -
buy the cable.
The following conversation was taken off a Z88 site.
I have transferred various files types on my z88 to a
PC. The other day, I
wanted to do the inverse process for the first time.

I wasn't able. I tried the Z88XPort program and the MS DOS
command, without good results. The z88 complains about "Poor
data received".
Have you checked serial settings? Reset turns Xon/Xoff
back on, make sure it's turned off.
Yes the problem is that I am able to send a file from
the z88 to the PC, but not in the inverse direction.
As Vic points out it is likely a cable problem.
So, is it possible to have a cable allowing transferring
to the PC but
failing when transferring to the z88 ?
I'm using a Compaq PC Laptop with Windows98.
Z88-Xport needs a working hardware flow control. Z88 RTS
needs to be connected to PC CTS. See Help, Cable for the full
pin out. Xon/Xoff is ignored so doesn't matter.
The cable I am using is a self-made one. I have followed
the wirings given in the z88 book:
Thank you everybody. I've re-wired my link cable, so everything
works now. It's a shame I saw that wiring scheme before yours.
:-D
