.CHK

 EQUB 0

\.CHK3                  \ These instructions are commented out in the original
\EQUB 0                 \ source

 SKIP 12                \ These bytes appear to be unused, though the first byte
                        \ in this block is included in the commander file (it
                        \ has no effect, as it's the third checksum byte from
                        \ the Commodore 64 version, which isn't used in the
                        \ Master version)
