 (the timing might be tricky here. it might be better to have the io device buffer the data as soon as it is selected. or maybe it’s even more complicated than that.)

 > The emulator doesn’t have a reader that can read real cards, so, instead, binary cards are in a file with a “.deck” suffix that contains a sequence of binary words, each corresponding to a word on the card. One card follows another in the file, so the first 24 words are card 1, the next 24 are card 2, and so on.

+## Keypunch & terminal history
+
+Q: were there any teletype-style terminals with integrated card punching?
+
+The Teletype ASR33 (and others) had paper tape, but I don't know if any could do cards...

+
+> **IBM 129 Card Data Recorder**
+>
+> Introduced with the System/370 in 1971, the IBM 129 was capable of punching, verifying, and <mark>use as an auxiliary, on line, 80 column card reader/punch for some computers</mark>. A switch on the keyboard console provided the ability to toggle between the punch and verify modes.

+
+> Two types of terminals are available with TSS/360: the IBM 1050 Data. Communication System, with an IBM 1052 Printer-Keyboard and an optional IBM 1056 Card Reader; and the IBM 2741 Communication Terminal.
+>
+> The IBM 1050 data communication system is a multi- purpose terminal that can transmit and receive infor- mation to and from a central processing unit and, also. can be used to produce documents and cards, in the off-line mode. The IBM 1050 consists of a control unit and a keyboard printer.
