3370 disks

The 3370 HDA (Head Disk Assembly) was about 500MB, so there is 1GB here. I have 32GB in my iPhone today...

Also with a flat-bed 8809 reel-to-reel tape drive on the end. Don't recall them going wrong too much. You could use a socket spanner to winch up the flat-bed deck to almost 90 degrees vertical for servicing.
