ahh, the HP 9133A - the largest and heaviest external 3 1/2" floppy drive ever built.
-
unfortunately the floppy drive isn't quite working. i can't format this new disk. the drive makes a very rattly sound, so it's probably something mechanical.
3 1/2" = light mode
5 1/4" = dark mode
-
huh, i reconnected everything and plugged the drive into my HP85, and it actually works! i can read the files on it.
Oh pretty HP85. HP and 3M executives never suffered the pain they should have for inflicting those damn DC100A cartridge/drives on users.

@darryl_ramm yeah those are awful
-

@xan they are HPIB which is technically not GPIB. but basically yeah.

@tubetime I knew it! They've got that testing equipment physiognomy (I wanted to say HPIB originally but I was honestly expecting to catch heat from somebody saying "WELL ACKSHUALLY" in the other direction)
-
@darryl_ramm yeah those are awful
It's not like they were ever that reliable to start with.

Thanks Philip et al. My 85 and 87 have them.

@darryl_ramm i have one in this machine.

one of the programs.
Cool!

@tubetime so gorgeous and stunning

If you have an easy way to accomplish it, can you send me listings of some of the programs, so I can work on the BASIC lister code ?
For instance the "BIORHY" program, which I suspect is a HP demo ?

@bsdphk sent you the file in an email.

Thanks, got it.

5 1/4" = dark modegot some time to take the drive out again and clean it again. i ended up having to remove this entire sliding side plate because there was still some old crusty lubricant. it is much better now. i also lubricated the head stepper worm gear.

much better, it actually formats the disk! BTW this 3 1/2" format is very odd. 600 rpm, 66 tracks, 16 sectors per track, single-sided, 270K capacity, 256 byte sectors.

why all this work? i need to work with some very early 3 1/2" disks. this example has an oval window but more surprisingly, the disk shutter must be opened manually before you put the disk in the drive!

and it actually reads! at least, it recognizes the LIF volume label. the filesystem is for a different type of computer, so the HP85 doesn't show any files.

@tubetime Verily, it is not a micro floppy disk.

@tubetime You say “worse,” but all of this sounds awesome.

@tubetime Boy howdy, this thread is quite the read! But back in the day where things were slow and relatively simple, things were more fixable, too. There's no squeal that lube can't fix--just don't get it on where the data is. I marvel at the post talking about head crashes "from time to time" but resuming use after each time. Good ole days. Anybody perchance own an old computer that used bubble memory? In my lifetime, I've seen only one of those in person.
