Poll: who still uses RTAI-only hardware drivers? (STG, Motenc, VTI, EVOREG, AX5

I don't recommend this kind of fun to anyone, but LinuxCNC with Trixie can be installed and run from an 8 GB partition.
For a standard xfce4 installation, 16 GB is enough.
I'm talking about just LinuxCNC without any CAD/CAM or other utilities.
Of course, today it is difficult to buy such a small disk and there is no technical or economic justification for it, but it gives you an idea of ​​how much is needed.

Moderator tommylight indicates that no 8255 is installed, instead, there's just a parallel port?  I'm using the "native" parallel port on the Compaq Presario,  Running dmesg on the rtai kernel says:
parport_pc 00:07 reported by plug& play ACPI
parport0 PC-style @ 0x378 irq 7 [PCSPP,EPP]
lp0: using parport0 (interrupt driven)

This could mean there is a version of linuxcnc kernel that already supports a "native" parallel port.  Certainly if there's an ISO image that already supports a parallel port my hardware setup isn't going to have the desired affect of testing against an 8255. 



 

parallel port is supported, you can already upgrade and use parallel port, I did not understand what Tommy's comment was referring to, my bad...

then nevermind we do not have testers for these very old drivers, we will cleanup...

My reply was that i use parallel port on several machines (over 10 for sure) with RTAI kernel, and use RT-Preempt on new-ish PC's for parallel port and Mesa boards.
In total, easily over 50 machines.

I do have a PCI board that i have to spend some time with, got it from a friend so i have no clue where he got it, and another set of boards that was driving a 5 axis machine, from initial tests i did back then all are recognized by older kernels, but will probably need drivers and i am not in the mood of writing those.

Got it, moving eventually to uspace is the right move...
