Editing PETSCII (section)

==History==
The character set was largely designed by [[Leonard Tramiel]] (the son of Commodore CEO [[Jack Tramiel]]) and PET designer [[Chuck Peddle]].<ref>{{cite journal |last1=Reunanen |first1=Markku |last2=Heikkinen |first2=Tero |last3=Carlsson |first3=Anders |title=PETSCII – A Character Set and a Creative Platform |journal=Replay.

The Commodore 64, however, used a slightly re-designed, heavy upper-case font, essentially a thicker version of the PET's, in order to avoid [[color artifacts]] created by the machine's higher resolution screen.  The C64's [[lowercase]] characters are identical to the lowercase characters in the [[Atari 8-bit computers]] font (released 2.75 years earlier).

Peddle claims the inclusion of [[Playing card suit|card suit]] symbols was spurred by the demand that it should be easy to write card games on the PET (as part of the specification list he received).<ref name="On the Edge"/>
