Miscellaneous illustrations used in the interfaces of SPC products or in prototypes of products. These were hand drawn. They required a lot of pixel level editing. They were limited to the standard 16 system colors available at the time. Various colors were achieved by dithering from the 16. Anti-aliasing was used to lessen the jagged appearance of rounded or diagonal lines. This was done by adding intermediate shades between the background color and the foreground color. These were created long before there was Adobe Photoshop, so all this was done by hand, one pixel at a time. Donated by Jeff Conniff.
