The first Amigas stored their Kickstart on special Kickstart floppy disks.
This Kickstart version (1.0) was only available for the Amiga 1000.
Kickstart 1.2 was the first version used for the A500 and A2000.
This Kickstart version (1.3) was used in all available Amigas at that time (A500, A1000, A2000 and even the CDTV).
First, I roughed out the picture using Line-Draw and Fill.
Next, I blocked in major areas of light and shadow.
Third, I switched to Freehand Draw and "loose pixel" brushes, and modified the color palette.
Finally, over two more days, I worked on the details using Magnify-Pick Position mode to complete the image.
