I don't know where this guy got them from, but these disks are from Patti.
The seller posted a box of 3.5" disks. Whoever had them was an early mac
developer.

I'd care more about them if I didn't already have another copy read.

At least one matches what I have. It is rev7 Mac rom for sony
Will be interesting to see if anyone figures out what they are

Someone on the Apple Lisa Facebook group mentioned posting these Twiggy disks plus a handful of Mac Supplement disks. No idea if they realize the significance.

So interesting that someone was still using Twiggy FileWare disks even into February 1984.

Why? Sony 400K disks had less capacity, but everyone with a Lisa surely had either a ProFile or a Widget. So this must have been someone's backup copy, right? That's why they're all dated: because they're someone's point-in-time backup copy.

Second interesting point: starting bid for this auction was $349 and the auction duration is only 1 day. Surely the seller knows he can realize a much higher final sale price with a 5 or 7 day duration! Why such a short auction which will only serve to limit the sale price???

Third interesting point: I don't see the MacWorks sources on the Bitsavers archive anymore.

they were a partial set
their presence on line may interfere with an upcoming project


and it turns out the twiggies in the auction are just the headers, not the sources

I was going to do some back-of-envelope math to figure out if ROM sources would even fit on those couple of Twiggy disks, based on that set of 4 on 400K Sony disks.

So those disks just have the EQUate files? How do you know?

Oh, are these the Developer disks that came with the Software Supplement? These are the disks that 3rd party developers got before Workshop was ready to use to make Macintosh software.

ROM7T: in the set is for the twiggy mac

I hadn't seen this doc before, it is buried in the early mac developer notes at
https://archive.org/details/MacintoshDevelopmentNotes
pp 75-85
mac development was done using the pascal monitor.
