Most operating PDA machines have the Turbo Cam controller.  It was original equipment on the newer machines and

retrofitted to many older models. This is a reliable Pentium  based control with either a Disk-On-Chip or

Compact Flash solid state hard drive. An older version of this control is the Camstar with a 486 PC

Tera 4031 controls were used on some older PDA machines.

Left unsupported are PMC, Spectrum, and General Automation controls.
