If you are looking to reduce hardware expenditures, I know of at least
one engine controller that was done for the navy using PC-based hardware
and GE Fanuc I/O control blocks. On the ship shock and vibration was our
main concern, so we found a moderately rugged touchscreen PC with PCMICA
support, and replaced its hard drive with a solid-state PCMCIA hard
drive. With a bit of hoofwork by your EE/ME folks, you might be able to
come up with some PC-based solutions that will work in your environment.

But the neat thing is that it ran NT (insert laughter here). Yeah, yeah,
I know; but that meant we had a relatively large range of tools and
vendors to choose from for our software development environment.
