Overflow?

["Sauer" <laserdog@bright.net>]

I bought "Mystery House" from the "Big Red" fellow years ago when it went
public domain. I wanted to send a copy of it and in the process I decided to
look at the game. When I booted it on my Apple II+ I got an"Overflow error
#5". The copy had the same error.  However when I booted the same disks on
my Apple IIGS and Apple IIe this did not happen. The person I am sending
this to has the Apple II+, will this occur on his machine too or is this
just my problem?

Thanks for any suggestion.
