There's been discussion of this on the VCFed forum, but it doesn't look like anybody's brought it up here yet. Per Mike Brutman, list member Chuck Guzis a.k.a. Chuck(G) passed away recently. He was highly knowledgeable, a full-bore storage expert, and an all-around even-keeled decent sort, and will

I've been looking for these removable drive cartridges for years with no luck. Sysgen called these DuraPak's and SyQuest called them Q-PAK's. I'm not sure why they had different names. On Sun, Jul 20, 2025 at 9:25 AM Peter Ekstrom via cctalk < cctalk@classiccmp.org> wrote: > I am looking for a

Wayne, I have an external SCSI and an internal SCSI ZIP100 for my two Amigas. I know they made a parallel version but I don't think I've ever seen a serial version. As in RS232. I used to have a USB version but it gave up. I guess if there was a serial version it could probably be made to work ove

I did find that out a little while ago. But the disks do seem as rare as hen's teeth for sure! I came across an SQ319RD drive for cheap a little while back and was thinking of trying to get it to work with one of my PDP-11s, but without a disk it is just a paper weight. Figured I'd ask here too but
