Macintosh PowerBook Duo 2300c/100 Install floppy disk set

Original floppy disk System 7.5.2 install set which shipped with the PowerBook Duo 2300c, as Disk Copy 4.2 floppy disk image files in a compressed StuffIt 3.6 ".sit" archive.

Note: This disk-set also doubles-up as an install set for the PowerBooks 190 and 5300. It contains and installs System Enabler "5300/2300/190 Enabler" (v1.2.1).

"Install Disk 1" through to "Install Disk 13", contain the main install set. Other disk images in this set are optional installs, except for "Disk Tools" image, which is the stand-alone "Disk First Aid" and "Drive Setup" tools boot floppy rescue disk for the PowerBook Duo 2300c.

Bundled software includes: Eric's Solitaire Sampler v1.0.2, Spin Doctor v1.2, Super Maze Wars v1.2a1

The PowerBook Duo 2300c/100 was released in 1995, the same year as its full-size sibling, the PowerBook 5300 series. These were the first portable PowerPC computers to be marketed by Apple. The Duo's PowerPC 603e CPU was designed for a 64-bit bus, but engineered by Apple to run on an older 32-bit bus to maintain compatibility with the earlier manufactured, Duo Docks. Potential system and video performance of this PPC Macintosh perhaps suffered because of this design decision.

PowerBook Duos lacked most common ports (featuring only one internal printer/modem serial port and an optional fax/modem card port). In their place was docking ability, accomplished via a unique 156-pin Processor Direct Slot (PDS) giving the docks full access to the Duo's central processing unit (CPU) and data buses.

Several dock options were offered by Apple and third parties:
Duo Dock, Dock II, Duo Dock Plus
Mini Dock
Micro Dock

The "Disk Tools" disk and the "Install Disk 1" contain the System Enabler "Minimum 5300/2300/190 Enabler" a cut-down version of the enabler to get the installer to run.

The full System Enabler, "5300/2300/190 Enabler" is installed onto the PB Duo 2300c's HD during the install.

@slomacuser: Yes, I see some discrepancies - in both uploads. Your upload (DL #2) has no Disk Tools image included and it is missing the "ARA Client Install 2" image from the Apple Remote Access folder. I assume this disk 2 is missing as the folder has a disk 1 and a disk 3 but no disk 2. Can you add this to the page, if you have it?

Yes, you are correct in that this could also be used with the 5300 & 190. But it was the 2300 that 1st included a "PowerBook 5300/2300/190 Enabler" in its install set. The original 5300 shipped with the "PowerBook 5300 Enabler", only. The PB 190 originally shipped with the "PowerBook 5300/190 Enabler", only. - While they were still in production they would naturally ship with the latest enabler (which I assume would encompass the 3 models), but that would have been after their original 1995 releases.

I'm now hoping to see the original 5300 disks surface with only the "PowerBook 5300 Enabler" on board.

First set is incomplete as compared to mine and it was not 2300 specific but for 5300 and 190 also so the title is missleading... or I am very wrong?
