Yes I worked on old computers too. Back in the 1980's even on high-end Sun
workstations I used to get up and get some coffee while the C compiler

You can't say "It is good enough because things were even worse 40 years

Out of curiosity. Why did you switch away from the BB and MK to LinuxCNC?

Is there a 'cape' currently available to suit the Beaglebone Black
running MachineKit or LinuxCNC?
