Will 486dx4-100 run stepster?

I saw somewhere that a 486-dx4-100mhz computer was fine to run Stepster on. I have a 10-20 in./min. application and a 486-100 w/24mb
ram. Are there any other requirements for hardware? I was going to throw an old 125mb hard drive in the box as the machine won't be
used for anything else.
I asked this next one before, but I thought I'd throw it out again. Has anyone gotten the Dro software to work simultaneously or
time sharing, on the same computer that is running Stepster? I would like to be able to confirm distances after moves. I know I can
do it w/2 computers but it means 2 monitors and there is not much room.
Thanks Bob
