29153: Unused

Code remnants in the routine at 29148. If this code were still in use, it would make the teacher skip wiping the board if it was already clean.
29153 | DEFB 127 | This was probably the operand of 'LD B,127'
29154 | INC C | C=1 + blackboard identifier
29155 | LD A,(BC) | A=number of the character who last wrote on the board
29156 | AND A | Is the board clean?
29157 | JP Z,25252 | Terminate this interruptible subcommand if so (there is nothing to wipe)
