- It might not be possible to port mtools to the Apollo under Domain/OS.
- A standard PC floppy disk (and a floppy disk on a Sun SPARCstation) uses
- 512 byte sectors. The Apollo floppy controller is set up for 1024 byte
- sectors, to be compatible with the blocksize of the standard Apollo file
- system.
-
- When I wrote PCdisk, a program marketted by Contexture, Inc., that reads and
- writes PC floppies on Apollo (and Sun) workstations (DN3X00/4X00 and 4XX),
- what I had to do is write a new device driver that saved the Apollo
- configuration for the controller, reset it and loaded the configuration
- appropriate for a PC floppy, and then set everything back to normal Apollo
- values after I was done.
