Hi, Okay, well I was told that my original images zipped up on the PC side lost the resource forks and other nuances of the Mac Disks with which they were written to originally... So, I went back to the Powermac, it creaked and moaned a bit due to some battery issues and corrupted HD, after a reinstall of OS 8.1 (7.5.3 just didn't want to cooperate today, though I did finally did take all of the 19 damned disk images and make an Install CD image of it all finally) I got the Mac back up and running... I know, I know... Mac's after OS 7.6 can't read 400K diskettes... WRONG! They can, but with a little help from a wonderful utility I found on macgarden.org called Diskdup + 2.9.2 (the earlier 1.3.2 does NOT work)... Read all of the disks in perfectly, even allows you to save them in its diskdup format or in Apple diskcopy format... So I saved them in both, plus I made SEA images as well just for good measure. Its late, I'm tired, and I need to catch up with some CPLD design work I'm doing, so this wonderful side project was a great diversion for a couple of days, but back to work... I will revisit my Corvus website in a week or so, make the needed clean up and link changes, plus add in some great photo's of a killer Concept setup sent to my by a former Corvus engineer... so I'll be working on the Corvus site more in a week or so... in the meantime: http://www.corvusmuseum.com/software/mac/corvus_mac_disks.sitx Curt
