Hi Paul,
There are some people who make basic CNC engraving machines from these parts using the stepper motors etc. Some videos are on Youtube.
There's a website called Amibay.com (I'm a member there) with people who buy, sell and discuss all manner of retro computing systems. Might be somebody on there who would be interested in buying your old gear or would take if off your hands if you just wanted to ditch it.
Regards,
Ed.
