What would be the point?

Before it was considered a bad idea, it was still available.  They are still 
available used.  I got one which hasn't been powered on in months.  Want it?

Emulators allowed use of discontinued architectures that people actually wanted 
to run.  I don't know anyone who really wants to run an itanic.  Do you?
