6 | /* This driver is for the parallel port hardware found on Acorn's old | ||
7 | * range of Archimedes machines. The A5000 and newer systems have PC-style | ||
8 | * I/O hardware and should use the parport_pc driver instead. | ||
9 | * | ||
10 | * The Acorn printer port hardware is very simple. There is a single 8-bit | ||
11 | * write-only latch for the data port and control/status bits are handled | ||
12 | * with various auxilliary input and output lines. The port is not | ||
13 | * bidirectional, does not support any modes other than SPP, and has only | ||
14 | * a subset of the standard printer control lines connected. | ||
