Hello..

This shall only be a little description how to use RasterCD on your Amiga.

This driver is a patched version of the TandemCD driver from Oliver Kastl
for the bsc Tandem-Controller. I wanted to build my Mitsumi-Drive with no big
amounts of money into my Amiga 1200 (Its in a desktop-case), and so i
developed a little circuit to connect it to the usual IDE-connector.
That looks the following way:


Amiga IDE                         CD-ROM

D8  (4)   ------------------------ HD0  (25)
D9  (6)   ------------------------ HD1  (27)
D10 (8)   ------------------------ HD2  (29)
D11 (10)  ------------------------ HD3  (31)
D12 (12)  ------------------------ HD4  (33)
D13 (14)  ------------------------ HD5  (35)
D14 (16)  ------------------------ HD6  (37)
D15 (18)  ------------------------ HD7  (39)
A0  (35)  ------------------------ HA0  (1)
A1  (33)  ------------------------ HA1  (3)
-IOR (25) ------------------------ -IOR (19)
-IOW (23) ------------------------ -IOW (21)

                #-----#
A2 (36)   -----1-I     I
                I >=1 I-3-------- -ENABLE (23)
-CS3 (38) -----2-I     I
                #-----#  <--  SN74LS32 or equiv.
                   
GND (2)    ------------------------ GND (all equal pins)
(19,22,24,26,30,40 are also GND)

Power for the 74LS32: PIN 7  GND (connect with the cable GND)
                      PIN 14 VSS (connect a wire and fix it to the +5V from
                                  your CD-ROM-Power-connector)

With this Hardware, the CD-ROM is selected in the lower 4 Adresses of the
Secondary IDE-Adresses, this means in A1200 $DA3001,$DA3005...

The base of $DA3001 for the A1200 is located at pos. 0x174 from device
beginning. for A4000 change it to $DD3021.

When your hardware is ready, connect the Harddisk and the CD-ROM to the
interface and turn your computer on. If your computer boots as usual,
the interface might be correct. If you want to check this, grab a kind of
monitor (C-MON or so.) and write a 00 to $da3005. (Byte). If the LED of the
drive flashes once, your interface must be ok. Then copy the rastercd.device
to your devs: directory and the CD0 and CD0.info to sys:storage/dosdrivers.

Put a CD-ROM into the drive and reboot your computer. While booting, the
LED of the CD-ROM should lit for a moment. If you are in the CLI, type

DIR CD0:

and you will see the result of your selfmade hardware. (If it doesnt work, 
dont worry, the circuit is not that complicated to debug)


Infos for the non-electronic-profis:

Connectors: (40 pin, used for CD-ROM and Harddrive)

A look to the pins (e.g. The backside of your CD-ROM): (LU-005S)

#--------------------------------------------------------------------------#
I                              ----------------------                      I
I        POWER            39 - I....................I - 1         AUDIO    I
I      CONNECTOR          40 - I....................I - 2                  I
I                              ----------------------                      I
I                                                                          I
#--------------------------------------------------------------------------#

For the cables: a little mark (red wire) shows Pin 1 (... say should show, 
there exist some connectors that show pin 40 instead)

The driver was tested with the MITSUMI LU-005S and should work also with
the FX-001D.

WARNING: DONT TRY THIS OUT WITH THE FX-300 OR FX-400, THEY USE ANOTHER
         INTERFACE !!!!!!!
