+ROM replacement for Apple II GP-IB controller to boot HP-IB devices.
+
+Feel free to clone and make repos for specific drives. I will add any
+links to those repos here.
+
+; Originally coded in 2009 by Matthew A. Hudson hexsane
+; at gmail.com
+; Code style & format borrowed from CFFA v1 source code
+; use ca65 to assemble (options elude me as I wrote this code
+; over a decade ago as I type this)
+;
+; HP-IB AMIGO protocol ROM replacement for genuine Apple II GP-IB controller.
+;
+; Was assembled and working for floppy drive in HP9133xv
+; It will work with the hard drive but you will need to change the
+; geometry and re assemble. 
+;
+; Note about assembly: I had to offset the code by either 128 or 256 bytes
+; (meaning you lose that space in the ROM) but I can't recall why. You may
+; need to fiddle around with options to get it in the correct location to
+; make the card happy. I've forgotten most of the Apple II I/O layout at this
+; point in time.
+;
+; There is probably code in here from other sources but I couldn't recall from
+; who at this point. If you see something that needs credit please let me know
+; and I will happily do so.
