I found a set of 9 x RX50 disks that appear to be Saturn for RSX.
I haven’t yet attempted to install Saturn on RSX, so I can’t verify whether this set is complete or error free.
What I have done is image all 9 disks in an 80-track 5.25″ floppy drive on an MSDOS PC using Dave Dunfield’s ImageDisk program.
Here are some observations about my attempt to image these disks:
- All 9 disks are single-sided, double-density, 10-sectors-per-track, 512-byte-sectors, 250kbps-transition-rate, 1:1-interleave
- All disks except 6 and 9 imaged successfully on the first attempt
- Disk 6 (GRF2) repeatedly gave errors when attempting to read Cylinder 63, Sector 0. I was eventually able to get an error-free read of this disk. “grf2a.imd” is the error-free image that should be used (ignore grf2.imd)
- Disk 9 (CAL2) repeatedly gave an error reading Cylinder 0. After about 20 attempts on 3 different drives I gave up trying to get a good read. Cylinders 1-79 were imaged without error. But for some reason ImageDisk reports that Cylinder 0 has one 250kbps single-density sector of length 0 bytes and no other sectors on that Cylinder. Perhaps this is part of a copy-protection scheme?
Here are the floppy disk labels, ImageDisk screen shots, and ImageDisk images for each of the 9 disks:
- sat1.imd (Diskette #1): Diskette label and ImageDisk screen shot
- wps1.imd (Diskette #2): Diskette label and ImageDisk screen shot
- wps2.imd (Diskette #3): Diskette label and ImageDisk screen shot
- wps3.imd (Diskette #4): Diskette label and ImageDisk screen shot
- grf1.imd (Diskette #5): Diskette label and ImageDisk screen shot
- grf2a.imd (Diskette #6): Diskette label and ImageDisk screen shot
- grf3.imd (Diskette #7): Diskette label and ImageDisk screen shot
- cal1.imd (Diskette #8): Diskette label and ImageDisk screen shot
- cal2.imd (Diskette #9): Diskette label and ImageDisk screen shot
The box of diskettes also included two other 5.25″ disks, which I’ve not yet imaged (click on the links below to see an image of the disk labels):
