I can ansewer your questions about the difference between the 88 and the 88hs. Very little. Neither have the additional PC that comes with the 32MP (inside the pendant). If your's is '95 it prolly has a 486 vintage PC right? Running windows 95...
Your MP32 should have a hard drive, can u boot that up when you switch to the PC mode?
You should be able to use dosshell to see the hard drive size...
On the CNC side of the mode switch you can get the memory available on the:
PA[enter]
then follow all the prompts, I think you should see memory there.
I've got a lot of advice, you can read about some of it here...

I personally would not be happy with the control for long, but I suppose it depends on what you need the CNC for...
