## Commodore 64 PETSCII Codes

#### UPDATE: January 22, 2018

The "Discussion" section below, replaces the original "notes" section.

#### Discussion

I have updated this PETSCII table to agree with the Vic-20/C64 SuperChart. So, please read the end discussion of that post for a more complete understanding of why the chart above appears as it does, and why it differs from the original source: http://sta.c64.org/cbm64pet.html.

The table above has been sub–divided into 8 blocks. This makes it easy to reference, because PETSCII is fundamentally divided into functional blocks of 32 characters each.

Blocks 1 and 5 ($00–$1F, $80-9F) are control codes. Printing them will cause a change in the screen layout or behavior, but no actually character will be displayed.

Blocks 4 and 8 ($60-$7F, $E0-$FF) are not used. If they are printed, the KERNAL will interpret them as mirrors of blocks 7 and 6 ($C0-$DF, $A0-BF) respectively.

#### UPDATE: April 16, 2018

I found this PDF description and overview of PETSCII on aivosto.com. I thought it might be of interest to anyone interested in PETSCII in more detail. I haven't looked over the document thoroughly, and I'm not responsible for any errors it may contain.
