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.

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.
