View source for 8bit Printer Port (Amstrad Action)

External 8bit Printer Port from ''Amstrad Action Issue 38'' (November 1988).

== Description ==

This is a rather bizarre [[8bit Printer Ports|8bit Printer Port]] solution. Aside from the 8th data bit, it doesn't come up with any other extras: Data is only one-directional, and only Strobe and Busy control signals are implemented.

Compared with the much older single-wire [[Happy Computer 8bit Printer Mod]] (1985), the Amstrad Action approach is terribly overcomplicated. And aside from that it isn't even backwards compatible with normal the 7bit printer software.

== Technical ==

Connects to the expansion port.
  Port  Bits   Expl.
  FBF8h N/A    Strobe (W)
  FBF8h Bit0   Busy   (R)
  FBF9h Bit0-7 Data   (W)
Writing any value to port FBF8h issues a short Strobe signal (the length of the signal is same as /IORQ ORed with /WR).
