How does your setup differ form the 1052 keyboard? I know that uses a
modified 024 keyboard, so interposers.
Under DOS/360, a user program could write a CCW string to ring the 1052
bell. If that CCW string included a TIC back to the bell-ring CCW, the
bell would just keep ringing with the keyboard locked out.
Fun and games, from very many years ago.

The keyboard on a 1052 is a keypunch keyboard I believe it is the same
as the 029. The printer in the 1052 is a keyboardless Selectric with no
tab rack and they spaced via a cam on the OP shaft instead of taking a
cycle. The ones I saw on a couple 360s (22 and 25) the space cam was so
worn it wobbled when it took a cycle, but the customer would never let
us do anything with it as long as it worked because they could not do
anything with out the console.
