@wilco2009 and TFM
[size=78%]Hi TFM[/size]Thanks I will have a look at 2.14


Wilco2009
I have solved some of the Problems by putting pressure on the Board .
Yes I have Cleaned the contacts, Resoldered the 50 Pin connector,  had my Valium tablets , and this is now Working :- Phewwww

It's great. I'm glad you've solved the problem, but that means it has no welded the board well. I'm very sorry.

[wilco2009]

Hi, if roman doesn't work then you can try to use my ROManager 2.14 (Link: ht tp://futureos.cpc-live.com/files/ROManager_ALL.zip). Why?

It will check every operation, does protect / unprotect etc. automatically. And the main screen will immediately show you if there is a problem or not.

However, you would have to install FutureOS to run it. Further I never used it for Wilcos expansion in person, but I had some guys doing test for me and so I think that's the best alternative for you. Let me know if I can help in any way. 

I would like to check Future OS with my expansion. I'll test it when I have some spare time. (I'm busy designing an interface for spectrum).


I didn't knew the characteristics you have mentioned and it sounds very interesting.

If you intend to use different Flash Chips just let me know and I can add that functionality. At the moment ROManager only supports Winbond and SST, because I think not other chips are in use.


Furthermore if you need special funktionality for MF+SX let me know and we can add that.

I have been trying to put Parados 1.1 or 1.2 into Slot 7.
I am unable to do it ??


?? How do I do it, What switches and the order of turning the switches on and off Please.


Thanks     RAY

On a CPC, internal ROM slot 7 cannot be disabled by an external extension. The ROMDIS signal only disable the FW and BASIC ROM. Put Parados in slot 6 or lower

Ok, Thanks.
I got tricked by the discussions on the Dual Roms Amsdos/Parados Switched.


Slot 6 Look out.


Thanks    Ray

On a CPC, internal ROM slot 7 cannot be disabled by an external extension.

Or cut the /CE track/pin or put a socket in on the internal 40015 ROM.

Or put on ROM6...

I was suggesting this before editing, but the megaflash does not support slot 7 anyway

On a CPC, internal ROM slot 7 cannot be disabled by an external extension.

I got two 6128 where this can be done. Using SF2. So you are right for some CPC, and for some not. Depends on the PCB obviously. I use an alternate DOS in position 7 with SF2 f.e.

[wilco2009]

In my implementation Slot 7 is used to store the alternative lowerROM, then it is not possible to store AMSDOS there.


You have to use ROM 6 or lower.


If Audronic have tried to write there He probably have overwrited the lowerROM and he have not the posibility to start with the alternative lowerROM stored there.

@wilco2009


Ok Thanks, I have rebuilt the FlashRom File removing everything except


00 Basic 1.1 (1.02)
03 Roman (1.00)
06 Parados 1.1
07 CPM Rom (0.05)
13 Romanger 64k (1.04)
14 Utopia (1.02)


All is working now.

Sorry, I've been slow to respond, but I'm not user of parados and I have had to refresh my memory.


By default Parados configure Drive A as 40 tracks single side and drive B as 80 tracks double side, because it, if you insert in drive B a disk with AMSDOS format you will get an error message.


If you want you can change this from the main menu of Parados. You can download Parados Manual in pdf from here: ParaDOS - CPCWiki


To load Parados main menu you can use |drive command.


Once in the menu yo can access to the configuration with Shift+C. Then press D to configure the drives.

@wilco2009


Thanks for the info.
I have tested Parados V1.1 and it works fine, Parados 1.2 has problems also with WinApe in Position 6, OK in 7.
I will be using Version 1.1 until the concern is resolved.
I have patched Version 1.1 to default to -  A: and B: 40 Track Single Sided.Change the byte at #1C00 from 03 to 00,

and subtract the 3 from the byte at #3fff to get the correct checksum.

The MegaFlash Plus SX is now working fine, ( I still have to put some pressure on the card for it to be stable ).

Thanks   Ray.

Have you given the CPC edge connector a decent scrub?

Bryce.

[Audronic]

@Bryce


Yes, I dissassembled the 6128 and cleaned all of the edge connectors (Both Sides), the Female edge connector on the MegaFlash Plus SX appears to be the reason that i have to put pressure on the board, i have resoldered the 50 pins and had a good look around the board and cannot see any other reasons for the problem.

Looks like ParaDOS 1.2 doesn't play well in slot 6, as |B doesn't change the drive. I'll look into it further, hopefully I can fix the bug and might need to release a new version.

[CraigsBar]

Ahh, well I have mine in slot 7, which explains things then.

[Audronic]

@Executioner

If you enter |B the light comes on Drive B
and  "READY" Comes on the monitor.
after issuing CAT it puts up the message about Drive A.
I don't have a disk in drive a only Drive B.

Hi TFM
Thanks I will have a look at 2.14

Ray

Did you have had a chance to use it? Would be nice to actually have somebody to confirm that it works.

Version 2.14 ??
Yes i tried to run the file as per manual  "   run"- romanager"  ?? Bad command
Tried   run"- romana.ger"  ?? Bad Command
renamed the file to -romana.ger   run"-romana.ger"  ?? Crashed.
at this point i gave up ??
This was tested on a 6128 with Megaflash Plus SX.

Err... no... that's very old stuff. I forgot one thing ROManager 2.14 need 128 KB. The 64K version is older but should run too. If you get a BAD COMMAND then you tried to run a binary.


Try:
RUN"-RMA

Should work. 


Newer version on my hp.

[Audronic]

@TFM


Please provide a link to the .dsk image and i will try it.
PS:- i have 128K in the 6128 ??


Thanks    Ray
