ahh, the HP 9133A - the largest and heaviest external 3 1/2" floppy drive ever built. let's get it working! 🧵

whoops, surprise hard drive inside!

this one is a Seagate ST-506, a MFM drive with a whopping 5MB capacity!

@tubetime Well that would explain the weight...

I actually hadn't known for years after the 3½" FDD appeared on PCs that full-height drives had existed earlier. Discovered this when I bought an Ensoniq Mirage, which booted off a 3½" diskette. A single-sided diskette, too.
