How do we know its a twiggy drive and not a standard 5.25" drive?
LOL, yes. And just look at that:… per above I’d actually call this thing slightly suspicious, in the sense that several Twiggy faceplates were known to be in circulation before the prototype with the drive in it surfaced a few years ago.
Another prototype with the drive actually still in there exists, and it’s a Twiggy. There were earlier stage prototypes that used Disk II drives but they predate the plastic cases. (Folklore.org had a picture of one I believe.) Note the case has no holes for a latch lever or door, Twiggy had power eject like Apple’s 3.5” drives. (Which from an electrical/interface standpoint essentially emulate a Twiggy because apparently Apple can never truly let a bad idea go.)
IEveryone tells the story as the Mac being conceived after the LISA
I did read an online article a couple years back that shows an early MAC with a Disk II drive.. Thats why I ask. Twiggy drives were just a bad idea. I guess I am almost glad I have a LISA 2 so I dont have to deal with them and "Make" my own disks.
It was Jef Raskin' project, running concurrently with Lisa that started out as a 6809
folklore.org may have the real timeline, I'm too lazy to look for it.
