I've been doing some work with some old PowerBook 1400s - I've had lots of luck taking the IDE HDD's out, putting them in a IDE to USB converter and then DD'ing them off. Several of them have worked fine just loading them straight into SheepShaver
Looking at them in Hex Fiend, most of them seem to be raw drives - beginning with signature "4C 4B 60 00 00 86 44 18 00 00 06" or "LK`D", same as if you create a new drive in Sheepshaver - however one of them, from a system that was running 7.5.3 and then upgraded to 8.6, is I guess Apple Partition Map? It begins with "50 4D 00 00 00 00 00 07 00 00 00 01 00 00 00 3F 41 70 70 6C 65 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 41 70 70 6C 65 5F 70 61 72 74 69 74 69 6F 6E 5F" or "PM?AppleApple_partition_".
This was the diskutil output for it:
