--
-- FPGA64 is Copyrighted 2005-2008 by Peter Wendrich (pwsoft@syntiac.com)
-- http://www.syntiac.com/fpga64.html
--
-- Main features
-- 15KHz(TV) / 31Khz(VGA)
-- PAL(50Hz) / NTSC(60Hz)
-- PS2 keyboard input with portA / portB joystick emulation
-- SID sound output
--
--
-- Internal emulated 1541 on raw SD card (READ ONLY) : D64 images start at 256KB boundaries
-- Use hexadecimal disk editor such as HxD (www.mh-nexus.de) to build SD card.
-- Cut D64 file and paste at 0x00000 (first), 0x40000 (second), 0x80000 (third),
-- 0xC0000(fourth), 0x100000(fith), 0x140000 (sixth) and so on.
-- BE CAREFUL NOT WRITING ON YOUR OWN HARDDRIVE
--
-- Use only SIMPLE D64 files : 174 848 octets (without disk error management)
--
---------------------------------------------------------------------------------
--
-- c1541_sd reads D64 data from raw SD card, produces GCR data, feeds c1541_logic
-- Raw SD data : each D64 image must start on 256KB boundaries
-- disk_num allow to select D64 image
--
-- c1541_logic from : Mark McDougall
-- spi_controller from : Michel Stempin, Stephen A. Edwards
-- via6522 from : Arnim Laeuger, Mark McDougall, MikeJ
-- T65 from : Daniel Wallner, MikeJ, ehenciak
--
-- c1541_logic modified for : slow down CPU (EOI ack missed by real c64)
-- : remove IEC internal OR wired
-- : synched atn_in (sometime no IRQ to CPU with real c64)
-- spi_controller modified for : sector start and size adapted + busy signal
-- via6522 modified for : no modification
