So I picked up a pair of TRS-80 Model 100s (Both were said to work, one does, one doesn't, I haven't gotten to debugging the broken one yet). Both included this weird floppy drive system. My googling has failed me, anyone know anything about them? Are they worth anything to anyone?

The seller also included these hard drive things, I'm not even sure if they actually go with the TRS80. Same question here, are they of any value to anyone? How would you even use these?

Thanks for your help!!
