Both SCO UNIX and Xsight say that 4 MB is the MINIMUM recommended memory configuration. It has been my experience that the minimums SCO recommends are the absolute minimums that you should even consider. You should have more. I found that even running XENIX 4 MB was not really enough memory if you are running large programs (like GNU Emacs) concurrently with Xsight. Did this person have 8 MB in his machine? That would seem to be a good starting point for heavy Xsight users running 3.2.

The run-time upgrade from XENIX 2.3 -> UNIX 3.2 cost me $325 as Softcare supported customer. I do not know if the price of the development system upgrade has been set yet. I do know that the development system started shipping just recently, so it will probably be a while before the DS upgrade is available. -- Terry Hull Department of Electrical and Computer Engineering, Kansas State University Work: terry@eecea.eece.ksu.edu, rutgers!ksuvax1!eecea!terry Play: terry@tah386.manhattan.ks.us, rutgers!ksuvax1!eecea!tah386!terry
