-imm4-90 High-Speed Paper Tape Reader
-
-The monitor PROM has support for loading BNPF or Intel HEX from this
-device (use J command to select it), but it doesn't appear in any
-catalogues or manuals I've seen. Apparently it was announced in
-Computerworld.
-
-In practice you needed a GPIO card (e.g. an imm4-60 or imm4-22) to talk
-to the paper taper reader. To simplify configuration we emulate the I/O
-interface and paper tape reader as a single device.
