Is this discussion based on an expectation of withdrawing RTAI
support? My impression from scanning PRs has been that RTAPI support
has been expanding, with improved support for RTAI and also for
Xenomai.
Retiring RTAI would be a LinuxCNC 3.0 thing. A lot of bitrotted code has
been fixed and Xenomai got fixed too. As long as the code is there, it
must be maintained.
The driver problem is that some of these cards are ISA and I have a hard
time believing that anyone would buy a fortune swallowing modern
industrial PC to get an old card working with a /new/ LinuxCNC. Even
with the PCI cards you'd have a very hard case these days.
If you use an old PC, then you may run into the problem of memory and
speed with any modern software. So you are still limited to older
versions/distros/kernels.
Nobody would build a new system like that today. Only (desperate)
repairs of old systems that cannot be upgraded right away would ever
reuse the old stuff.
If you ever upgrade these old systems, then you'd buy a newer more
capable PC/SBC and IO board with full support. And that would fill less
space and be cheaper to boot.
