Where to find the documents about QNX 4.23 ?

Hi,

We need to test and configure the QNX 4.23
at old system which version is 4.23.
We can not upgrade this system,
because the system is too old to support various hardware for latest
version.

Where can I find the information & help documents about QNX 4.23 ?

Thanks in advance.

when you have photon (older version <= 1.14) you get it there in the
helpviewer - also there
are some books on it from QSSL (the famous black ones :slight_smile:)

QNX 4.23 is not all that different from the latest QNX 4.25. There
was a big jump from 4.22 in that the OS in 4.22 was still 16 bit,
while the 4.23 OS was 32 bit. In both OS’s 32 bit processes
were supported. There were no doubt many bug fixes between 4.23
and 4.25, however the basics should not have changed much.
