DEC Professional 300 Series

Home » DEC Professional 300 Series

This page relates to the DEC Professional 300 Series computers, such as the Pro 350 and Pro 380.

Note: I am looking for a copy of the CP/M floppy disks to suit the Pro 300 Series. If you have a copy of this, or know where one can be found, please let me know!

Software

I found a set of 8 RX50 floppy disks, which appear to contain V1.5 of the P/OS Operating System. I don’t yet know whether this is a complete set.

I have imaged the disks using Dave Dunfield’s ImageDisk software. All the disks are the same format (80 tracks, single-sided, double-density, 250kbps, 10 sectors per track).

All disks imaged without any errors. Here is a screen shot showing the result of a disk imaging operation -> ImageDisk screen shot.

Here are the links to the disk labels (in JPG format) and disk images (in IMD format):
