Need v4.23 TCP runtime

An old customer of mine is still on 4.23. They needed to rebuild a node and
discovered their 4.23 runtime install disks were no longer readable. QNX
told them that they could no longer supply that version. Does anybody have
install disk images of their 4.23 TCP runtime disks that they would be
willing to share? Update images without license are fine. You can email to
ken at qsolv dot com, or make them available on an ftp site and I’ll come
and get them. TIA for any help you can offer.
