Melody 1200 Pro: anyone who can hack the driver??

[McTrinsic]

Hi,
after quite some time I was eventually able to get hold of a Melody 1200 Pro.

It is a know-good / known as working unit.

I have a Phoenix board and would like to use the Melody with the iComp A500-Clockport - adapter for the 68k-Socket.

Unfortunately the Melody is not recognized at the port that is meant to have the original A1200 CP-address.

The driver has this address hard-coded. A modified driver exists that allows the use on a ZIV-Clockports. Unfortunately this port in the A500CP does not recognize the Melody either.

I assume an issue with e.g. voltages or power.

I have a third option, as I have a VarIO with a clockport. From that clockport I have the base address and the CP-offset.

Anyone out here who could mod the driver to accept a different CP-address?

I have available the original driver plus the modded driver available. I tried to look with a hex editor for the usual address in the file but to no avail.

That would be the last thing I need to finish my 13-years-in-the-making-system .

Cheers,
McT

Diff'ing the two drivers yields too many differences to find out how the clockport address is coded in the driver?

[McTrinsic]

Right, nothing I would understand.

Did you diff the disassambled drivers? Or the binaries.

[McTrinsic]

Binary - don't have others.

If anyone is interested, I can upload both versions. The aminet download doesn't work anymore.

Thanks,

You can put them zipped in the zone. Maybe I can help a little bit.

[McTrinsic]

Thanks a lot!!!

Will do this evening, saw it too late yesterday.

You didn't understand the question or the result?

[McTrinsic]

The result .

I got some differences but couldn't spot the literal cp-addresses.

Thanks,

Hi,

the driver is uploaded in the zone:

MelodyPro1200_Driver_Orig_and_Mod.zip.

It contains the minimum installation of the original driver and a full package of the original driver with e.g. an adf.

Additionally, the modded files of the driver for use with a micronic ZIV board and the respective different clockport address is included.

Thanks!!

By the way: anyone able to reproduce this behavior? I.e. anyone have a Melody 1200 at hand and an A500 Clockport?

Cheers,

Can you be more specific as to where you would like the Melody to appear in Memory?
As far as I understand it, you would like to connect it to the second clockport on your iComp board?

Hi,

I would like to connect it to a VarIO board.

The A500 CP has two CPs with two addresses. The addresses are the one for the original A1200 and the one for the ZIV-Board.

That said should the original driver work with one of the CPs on the A500 CP-board. The modded driver should work on the other cp.

Since in my system the Melody doesn't work on either of them I would like to attach it to the CP of a VarIO board.

So ideally I would have an SPatch to hack in a different address.

For the VarIO, I have the base address and the clockport-offset.

Again: if someone has an idea on why the Melody doesn't work on the A500cp I'd be happy as well .

Thanks,
McT

Anyone??

[McTrinsic]

I guess this is not realistic, then ??

Still waiting for you to answer my question before looking at it:

"Can you be more specific as to where you would like the Melody to appear in Memory?"

I mean memory address range.

[McTrinsic]

Aaaahhhh... Now I get it .

I'll dig out the address later this evening.

Issue here is: it may be relative to the Zorro-Card the CP is on.

Anyways I'll get you the present address later.

Thanks!!!

Hi,

this one got me a bit puzzled.

The adress of the clockport....

The VarIO is the card that has the clockport.
The VarIO itself has a base adress of $EA0000.

The offset of the clockport is $c00 - $cffe .

Does that answer the question?

Or where do i get the Clockport-Adress?

Thanks,
McT
