Right, and right you are. If you look again, the the old Mac has been upgraded to 2MB RAM, SCSI, and 128K ROMs, so in effect it's a Mac Plus now. Just not as pretty or reliable. The CD has Appleshare Workstation, the version of CD driver that works with everything, and so on, so this Mac can play nicely with the big boys again. Fortunately, the CD was small enough that System 6 could handle it. An hour of glowing LEDs in the TurboNet connectors and 40 MB of stuff is back on the old girl. The original problem was that the server got a replacement boot drive a year ago, and it's too big for System 6 to mount. I think.

BTW, did you know that OS9.2.2 can handle large, as in 1TB+, drives? With Mac OS ROM version 9.5.1, my blue & white G3 has no trouble with its pair of terabyte Seagates under OS 9. Apple obviously added LBA48-bit addressing very late in the game.
