While scrounging around, cleaning out, I discovered a version of Electronic Workbench for a Mac with OS7.xx. No disc in the box but there were three nice written manuals (remember those?) I do still have an old Mac running a power PC. But wondered if I could lite this off on either of two newer Macs I've rescued from the trash: (1) 18"iMac running a PowerPC and a newer black Macbook running an Intel dual-core on their latest OS. Any Macperts out there know how to do this?
