I bought an original iMac at a rummage sale today, running Mac OS 8.6, PowerPC G3, 333mhz.
I have two classic Mac games in Mac format on a Windows 7 PC that I am trying to transfer to the iMac. One of the games is an image file in DMG format, which I have converted to ISO, and burnt to CD-R.
When I examine the CD-R on another Windows 7 machine, the files are intact. But when I insert into the iMac, I get the error "The disc is unreadable by this computer. Would you like to initialize the disc?" with two buttons, Initialize (format) or Eject.
I burned at 48x write speed, using MODE 1. The disc itself is a 700 mb Memorex.
I originally was to transfer the files over the internet, but there is no wi-fi support on the iMac and it's too far to hardwire via ethernet to my router.
Any ideas or suggestions welcome.
