Kodak CDL-144?

Hey all, I am not sure if this is the right place to ask (please flame gently if not), but: I have an old Kodak LifeSciences SCSI CD Library (model CDL-144) and haven't been able to find out very much about it. The robot component responds to the standard SCSI changer commands (as issued by, for example, mtx-1.2.18, but not mtx-1.3, AFAICT) and the drives of course open and close in response to the standard eject command, but I have not been able to figure out how to do useful things like open the mail slot, set the password, or dump (or update, if only I had an image!) the firmware over the SCSI bus. The only manual I've ever found online is just the "getting started" guide and points to kodak.com for more, but of course that's no longer around and even the wayback machine hasn't been that useful... thus this plea for anyone who knows anything about the device to share, even if off list. Thanks much in advance, --nwf;
