I am running Opus 1.73a.
I run barefoot, no front end mailer and no tosser.
The computer is a 386 DX/33 with 4 meg of RAM.
I use DOS 6.22.
I have never used a LAN.
I have never written any Opus utilities.  (If I could program I would write 
my own BBS software.)
 
Hmm.  I don't remember what else you asked.
