Linuxcnc 2.8.4 does not show tandem items.

Hi guys, I have an older PC that had the Debian Wheelzy iso with linuxcnc 2.7.14, I updated the repository link in Synaptic and then updated Linuxcnc to 2.8.4, but the "tandem items" do not appear when I go configure the parallel port pins.
 On one of the axes I have two motors and I want to do square homing as done in this video , but I don't have the "tandem option" to select the two motors and sensors which are on the same axis.
 I'm not using a mesa card, I'm using a PC with a parallel port, how can I solve it? Because from what I researched on the forum, from version 2.8.* of Linuxcnc there should already be this 'function' with tandem items...
 Thanks.

Download the 2.9.2 ISO and boot the PC from it, do not install, just use the wizard to create the config, save it to another USB or to hard drive, remove the USB, start the PC normally and use that config.

Hi Tommylight, thanks for the response.
I did what you indicated, I created the file in stepconf of Linuxcnc 2.9.2 and replaced the files in the old version (2.8.4) of Linuxcnc, but Axis does not open, there must probably be something incompatible between the HAL and INI files.
I tried to copy Stepconf from the newer version of Linuxcnc and run it on the old version, it didn't work either.
I verified that the Stepconf of the most current version runs in Python3, however in Debian Wheezy there is no 'native' Python3, only the previous versions.
Is there any other alternative for me to try?
Thanks again for the help.

Can you run LinuxCNC from the command line
to see what startup error you get?
 

I managed to identify one of the problems, it was in the name of the INI and HAL files, but after correcting it and trying to run Linuxcnc it showed an error.
The error report file is attached...

Have you fixed it yet?
