History in pics: Testing prototype Roomba's in 1982. It would take two decades until they could be made small enough to clean under a couch.
@SwiftOnSecurity looks like they were testing it to validate its interaction with washing machines in this picture for some reason?
@glyph @SwiftOnSecurity TFW when you wake from a mid-80s tech nightmare. You went to change the disk pack in the top loading hard drive for the S370 IBM. And it was full of water. The overnight banking reconciliation run would have to wait.
@jbond @glyph @SwiftOnSecurity how did water get in there?

@squareflair @glyph @SwiftOnSecurity

From the back of my mind. Deep in my dreams.

@squareflair @glyph @SwiftOnSecurity That was the dream world nightmare. The Real World nightmare IRL was the operator who couldn't work out why a disk pack wouldn't mount. So he took it out and tried it in the next drive. And then the next one. And now he had one pack trashed with a head crash and three drives with trashed disk heads.

ISTR they were 5Mb drives, but might have been 10Mb.

The year after that I had more disk space in my IBM PC XT than the mainframe had in one of those drives.

@jbond

is that basically like the zip drives were, a bad pack ruining good drives?

@chunter Yup. Except the disk packs were about 12" across and 6" deep.

@jbond I've been around them but I was 7 years old and only understood them as computer memory at the time
