HP was always fond of PURGE is a command to remove files.Īnyone Know what the Format Disc Command is Message #5 Posted by Steve (Australia) on, 4:26 a.m., There should be an ERASE command similar to the one for the tape drive. The DELETE command was used to remove lines of basic programming. Although the system was supposed to tolerate some disk flaws and create hidden dummy files on the bad spots, the early drives would reject disks with any errors.Īs far as deleting files from disks, I'm afraid my answer is going to be 65% guess. I think AMIGO 80 would merge adjacent blank spots to optimize space but it WOULD NOT move files to create space. This format would not break files on tape or disk files had to stored contiguously. The HP-80 series used a disk storage system format called AMIGO 80. Also its use is optional (I think - not really sure. The '2' in the above command is the disk sector interleave number - the value of 2 may be too low - I think 4 or 5 might be better. I'm pretty sure that the ':D700' was mandatory to avoid formatting the wrong disk due to a previous MSI command. Note: the curly brackets are not part of the commands The first command - both spellings were allowed. First you need to issue a command to define the location of the storage device. I'll try to help but this is from memory about 20 years ago.

What I am looking for, if someone has the data, are some commands that I can use to setup, copy, load, etc, programs and files between the HP-85 and the Floppy

I don't have any documentation on the Mass Storage ROM or the HP-IB interface. I even have manuals for the 85 and the Disk Drive. HP-85, H82937A (HP-IB interface), 82901M (Flexible Disk Drive) and a Mass Storage ROM. Need: Basic HP-85 I/O Commands to Floppy The Museum of HP Calculators
