Yes--and the printer options were rather limited.  I remember having 
to print to disk and then use my own program to translate Epson 
graphics to the printer I had at the time.  The library wasn't the 
greatest, but it was pretty simple to add parts to it.

All in all, for the limited hardware it had, it wasn't a bad system.  
I used it quite a bit, even if it meant taping together sheets of 
tractor-feed printer paper.  It was still easier than drawing by hand-
-and you got some very rudimentary design checking and a BOM.

One of the first programs for which I used a mouse.
