macintosh links ?

Greetings to all,
Just been given 2 macintosh Classics.(cute little things)
both in a1 condition, wondered if i could use one to
control a single stepper size 23. anyone got any links
for software, hardware, or any info ? they are just the right
size to fit in my very cramped workshop,or perhaps i could
use the monitors with a PC.
grateful for any help
Ian.
