RE: [CAD_CAM_EDM_DRO] Homebrew DROs

As far as I know you have found what there is. For the PC there is the
Kulaga/Mauch design that uses a dedicated ISA card and there is also the
Lindsey (?) design that uses the parallel port. I don't know of any
published design on another platform. Should be reasonably easy to do on a
palm or a micro using one of the USDigital encoder chips. Best non-surplus
source for encoders I know of is USDigital at www.usdigital.com Don't know
if they have a UK agent.
