My first reaction is that the newer kernels have no ISA support without building your own and configuring that option back on, if it still exists in the latest kernel src linux needs to run well. Realistically, ISA has been dead and had a few words said over it for at least 15 years. PCI is around 10-30x faster as the 7 MHz clocking was replaced with 33 MHz clocking, and offered bus widths up to 64 bits, whereas ISA was stuck with a 16 bit data bus. Even that is considered slow these days. I'd not recommend a raspberry pi 3b at this stage of the update your hardware game, even if mine is running linuxcnc again. I'll have another post about that, but probably after I go round up some dinner for us, I have a theory I'd like to expound on a wee bit. Film (term used very loosely) at 11.
