I would've thought that Tetris would switch to the VT52 graphics set,
which wasn't emulated by any subsequent DEC VT. However, a full block in
that case would be 141 ("a"), not 177, which is DEL, so I assume Alexander
is saying that the VT52 displays a block when receiving DEL. Other DEC VTs
ignored DEL on receipt, even (I believe) in VT52 mode.
