I’m looking for print versions of the following QNX manuals:
Utilities - A to M (for QNX 4.23 or later)
Utilities - N to Z (for QNX 4.23 or later)
Installation & Configuration (for QNX 4.23 or later)
System Architecture (for QNX 4.24)
X Window System - Installation & User’s Guide
I found PDFs on QNX’s website, but these are 4.25 (or later).
Log into your myQNX account, and then click on the Downloads menu. You should be able to find the PDFs under QNX 4 RTOS → QNX 4 Operating System → QNX 4.25 Documentation in PDF. You might have to have registered a QNX 4 product on your myQNX account in order to access the QNX 4 part of the Download centre.
There are also PDF versions of the documentation for other components of QNX 4 (e.g. Watcom C Library Reference, TCP/IP).
