 In general, no.   Now, before the flames start; allow me to finish... 
That can be a hard question to answer.  The IBM 5100 that I acquired
several months included the printer, an external tape drive, and a
monitor.  All of this was at no charge.  Having just seen pricing on
just the 5100 ranging up to $500 or so, I went ahead and told this
person about it.  They responded by saying not a problem, and for me to
enjoy.  In general, I have found that being a fairly avid collector
makes it much easier to deal with people who are looking for a good home
for their old computers.
