I did replace the RZ25 drive with a ZuluSCSI and have it emulating a couple of RZ25s. I have VMS 5.3-1 up and running. I used the licenses from the OS that was running on it. I also have it on my DECnet network with my PDPs. The PSU looks great and the battery is not a problem either. The CDROM drive I got works great in an old Sun 411 enclosure attached to SCSI-B. I haven't used the TZ30 tape drive yet. I am going to see if I can treat the tapes I have to some time in the dryer and see if that helps. I think the surface of the tapes has softened and is leaving residue on the r/w head. I have read of some folks having success with the dryer. We shall see. But for now I am quite happy with it. Thank you everyone for all help and advice! - Peter > On Mon, Dec 1, 2025 at 10:30 AM emanuel stiebler <emu(a)e-bbes.com> wrote: > >> On 2025-11-30 14:53, Peter Ekstrom via cctalk wrote: >> Very interesting thread.
