Apple Operating Systems

I felt like pulling out my emulator collection this evening, so then I thought I'd see how many Apple OS's I could jam onto my iMac 27" screen at once. The answer is quite a lot, but fewer than I'd hoped—I may have to re-do the challenge including my second monitor.

Anyway, for your enjoyment, here it is. Click to expand:

The emulated systems are, left to right, top to bottom:

1. Macintosh System 1.1 (showing the early Control Panel)
2. Macintosh System 2.0.1 (running MacPaint)
3. Macintosh System 3.3.0 (running the Scrapbook Desk Accessory)
4. Macintosh System 6.0.0 (showing the newer Control Panel)
5. Macintosh System 8.5 (running CyberDog)
6. Apple 1 with a simple Hello World program entered into the WOZ Monitor
7. Dos 3.3 (running Beagle Bros Apple Mechanic)
8. UCSD Pascal OS
9. Prodos 1.1
10. Apple /// SOS
11. The Lisa Office System (running LisaCalc)
12. Newton OS (running on an eMate 300)
13. NextStep 3.3 (running Mail.app - not strictly an Apple OS I guess)
