Autohelm ST7000 Course Computer

[KenVincent]

I own an older Autohelm ST7000 that uses the Z083 course computer. I think that unit needs to be replaced, as all the other components seem to work OK. Can I use the newer Raymarine Type 300 computer and keep the drive unit, flux gate compass and control head? It seems a terrible waste to have to replace all those expensive units just because the course computer is obsolete.
