Feel free to clone and make repos for specific drives. I will add any

links to those repos here.

|
|
; 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.
