I was able to get the video working on the 6100. Just did the quick on and off of the power switch. It booted up fine. It is running O.S. 7.5.5 with a total of 16mb of ram. There is also a 16mb strip of ram on the DOS card. The floppy drive works fine. This one does not have a cd drive. But I may add one as the cable is there . I will do some reading so I know how to get the Windows partion on the harddrive to show. The unit cleaned up well, just a little yellowing on one corner of the case. An interesting vintage PowerMac.
