For those curious about CAMAC controllers, this one was built around 2014 to 
replace the aging CAMAC A1/A2 controllers (parallel and serial) in the TRIUMF 
cyclotron controls system (around 50 CAMAC crates). It implements the main
and the auxiliary controller mode (single width and double width modules).

The design predates Altera Cyclone-5 SoC and has separate
ARM processor (TI 335x) and Cyclone-4 FPGA connected by GPMC bus.

ARM processor boots Linux kernel and CentOS-7 userland from an SD card,
FPGA boots from it's own EPCS flash.

User program running on the ARM processor (i.e. a MIDAS frontend)
initiates CAMAC operations, FPGA executes them. Quite simple.

K.O.
