I have a HP 9133 combo disk drive connected to an HP 9000 model 310 computer running Basic 4.0. This setup is used to control a few machines, and does not have a floppy inserted.
The hard drive is getting dated, and I am worried that it will break soon, rendering the machines unusable. To that end, I would like to copy the contents of the disk as an image, and emulate the hard drive using a modern computer via this PIC emulator, the HPDrive Project, or something similar.
The problem I have is how to copy a disk image off of the 9133 to be able to use the above tools. In researching options, I found BASIC commands to copy files, but none to directly copy the entire unformatted data on the disk. I am not beyond spending money on a device that will do this, and my focus is on trying to do this with minimal effort.
The computer starts by running the Basic program, and I am left without a command line (or much knowledge of old computers, though I do know basic decently).
