@ -7,6 +7,10 @@ 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) to talk to the
paper taper reader. To simplify configuration we emulate the I/O
interface and paper tape reader as a single device.
