Hi guys!
I'm sure that all of you know the Megaflash from Bryce.
Some time ago I made a new board with different layout but using the same scheme.
Based on the study of this schema and the knowledge contained in the wiki I have designed a new improved version of the megaflash with the following differences:
- It is possible to include lowerROMs in the flash chip. Now position 7 is reserved to include a lowerROM (in the same way that XMEM card from cent pour cent). Now the CPC can start with this lowerROM together with the ROM0 contained in the flash memory.
A second lowerROM/BasicROM set can be selected using slots 30 & 31.
- Footprints for MX4 and EDGE connectors are included.
- A IDC26 connector is included to connect directly my multisystem floppy controller.
I'll make a short batch of it soon. Price will be around 20€ in kit format and 25€ assembled plus shipping costs.
If you want to make it by your self, I will publish all the necessary information here.
Bellow you can find some pictures of the board, being used with the floppy controller.

I add some additional comments about the assembly and the use of the switches bellow.
I have started to send packets, but I have a problem with the IDC connectors. Provider have sent me connectors with straight pins instead connectors with right angle pins. He has re-sent them.
- In the board R4 is 4k7 but I have changed it to 1K. It is due to the fact I have used a 74HC374 in the prototype, but the chips I bought for the kids are 74LS374. I thought it will have not any influence but, it has not been so.
- Switches are a model for pcb. To use it in the box supplied you can used two different methods:
1. Led and switches installed in the top of the box. To do that you can weld the switches on the surface as a SMD component.

Once the board is mounted, you have to make the holes in the top of the box to permit the access.
2. You can install all the selectors and led in the bottom side of the board.
In this case you have to make the holes for the switches in the back side of the box.
JP3 is just to disable the interface. It is not necessary to access from outside the box. If you need to use it you can open the box to access.
USE OF THE SWITCHES.
We have a total of 4 switches in the board. I will describe their funcionality looking from the front of the CPC with the interface connected.
JP2: At the top right. Initially it could be used to select lower ROM 0 or 1 in the flash memory. Now it has no use, but I left it there for futures updates.
JP1: Used to activate internal (CPC) or external (interface) lowerROM. To the left external lowerROM is selected.
S1: Used to activate the write mode. To avoid corrupting the flash memory is important to keep it at left (LED off) except of when it is required by the system.
JP3: It is located at the bottom right and it is Used to deactivate the interface. Interface is active when the switch is at top. To deactivate the interface JP3 have to be at bottom and JP1 to the right.
The GAL is already programmed with the correct equations and the flash memory is burned with a starting up set of ROMs and unprotected.
Flash memory have installed ROMAN, and a 64Kb version of the TFM's Megaflash ROM manager (it starts with MODE 2:|rme)
Flash memory have installed a 6128 lowerROM modified to intialize 32 ROMs and their corresponding BASIC.
I'm sorry for my English.
Below you can find pictures of the MX4 version. It is important to take care with the connector position.

OK, Audronic.
I'll send you the details by private.
Added all the necessary information to build the board.
Nice use of diodes to reduce part count.

Thanks Bryce.
I afraid that I found a bug in the GAL equations of my Megaflash SX. I have been working some time in it but it is not solved yet.
The bug consists on some random writes in not correct places. After some time of work, writing, erasing etc, the content of the flash will be corrupted.
As I said I have made some progress but is not solved yet.
Until now, two people have paid the kit. If in a week I have not found a solution, I'll return them the money and I'll collect the money again when the problem have been solved.
Anyway, because the list is there, I'll keep with the list of the people interested in the project.
Now we are 23 (24 with my kit). Due to it left 6 kits to fulfil a batch of 30 kits.
I have found a solution to solve the problem and the interface is now operative.
To use two lowerROMs were not possible because, when I added the equations the Megaflash, it sometimes was writting in incorrect places.
Then, the Megaflash SX will store only one lowerROM.
The second selector will be used to deactivate the interface in the startup. It could be usefull in case of corruption of the flash memory. You could populate it again from disk.
Due to it I can say we can follow with the project.
If anybody would want to be removed from the list because the lack of the second lowerROM, please let me know it.

Thanks for the update. There is a newer version of my ROManager at www.futureos.de (http://www.futureos.de) If somebody does use it please make a picture and post it here, so I can see which Flash is installed and (if needed) extend the ROManager for new features.

It will not be possible to fit more than 3 boards on the MotherX4, except is the passthrough connector is not used.

It is because the board is the same for the EDGE connector and the IDC connector. The EDGE connector sets the order of the holes.
Allways it is possible to use the last connector. Then you can use 4 boards.
?? It would have easily been possible to put the connector on the other side and still be compatible with a stand-alone connector.

If you put the connector on the other side, upper row in the interface is connected to bottom row in CPC and viceversa, for instance pin 1 is connected to pin 2 and viceversaOr do you mean another thing?

Only because you laid it out that way. All other cards have managed to put the connector and components on the same side and still be compatible with a normal flat cable too.

The same board is compatible with EDGE and IDC connectors.
If you put the EDGE connector in components side, then components are facing the CPC, and it is not possible to connect them right.

How do I reset the Flash Memory ?
Ray
Quote from: Audronic on 05:07, 04 December 15
Oops
How do I reset the Flash Memory ?
Ray
To initialise the flash memory you can run ROMAN from disk.
From the main screen enter in the System Menu pressing "y"
Then you can erase the entire flash memory pressing option 4.
Once you have deleted all the memory, you can populate again the memory with the ROMAN it self.
When you finish, could be interesting to protect the flash with the option "1" in the system menu. (remember to unprotect again, option 2, when you need to populate with new ROMs).
For this operation you will need full access to the flash memory, then you will have to change the lowerROM switch and the write switch when CPC ask you to change to write mode.
REMARKS:
To install the lowerROM you have to save the desired lowerROM in the slot 7. When the program ask you to change the swith to write mode then you have to change both (write switch and lowerROM switch), and return to their original position when CPC ask for turn off the write mode.
LowerROM is not showed, but it is there.
To start with the new lowerROM it is also necessary install the BASIC ROM in the slot 0.
If the flash memory is corrupted and you can't start the system with the Megaflash plugged in, then you can change the switch in the bottom back of the interface to disable the interface during the start up.
Then return the switch to the original position and load ROMAN from the disk to erase all and populate again.
Hi Wilco2009
I have tried all of the above.
I have had no success programming the MegaFlash on my CPC6128.
I have Read the Rom from the other unit i purchased from you in an Eprom Programmer (TOP853)
and dumped it in the Rom of the first one (edge Connector)
The Megaflash Plus SX now is able to boot , read the Roms etc.
BUT if i try and WRITE to the Rom it performs all the actions on screen OK but does not WRITE to the ROM successfully.
I have had a look at a Dump of a Rom that i tried to write to and it puts some garbage into the Rom (Checksum Changed).
The model i am using is the EDGE connector version.
I have tried to do .
1) Unprotect the Rom.
2) Initialise the Rom.
3) Erase all 32 Roms.
None of that works ??
What can i do to get this to Write to the Rom ??

When the chip is dumped with an EPROM programmer it left the chip write protected.
The esasiest way to unprotect the chip is to use the unprotect function in the programmer.
It must be possible to unprotect it from ROMAN, but if you are still having problems I'll check it in my interface when I will return to home next week.
Hi Audronic,
I had some issues last year with a Megaflash and not being able to write to it from the CPC.
Anyway, check this out from almost a year ago (I have just done a couple of all dayers / all nighters at work with some major issues so I'm running on minimal sleep and this may not be 100% relevant, but from initial quick read it sorta sounds similar...maybe...).

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. :)

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

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.
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.

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 (http://cpcwiki.eu/index.php/ParaDOS)
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 (http://www.cpcwiki.eu/forum/index.php?action=profile;u=952)
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.
@Bryce (http://www.cpcwiki.eu/forum/index.php?action=profile;u=225)
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.
Ray
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.
Ahh, well I have mine in slot 7, which explains things then.

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.

The ROManager 2.14 that TFM linked to is not an AMSDOS program, it will only run under FutureOS, that's why you will need to install the entire OS and run the Manager from within this OS for it to work.

Sorry, there is no current ROM version,[nb]Latest release is some where on my homepage, should be version 1.45 or 1.47. Goto www.futureos.de (http://www.futureos.de) and there click at downloads, then scroll down.[/nb] due to a lack of time.[nb]I have separated source for ROM and disc versions. Since the underlying user interface CBM got improved recently I focused on one version. To integrate this all in the ROM version will be lots of work and maybe one day I will find the time. But I'm afraid not so soon. My day time job keeps me busy. [/nb] But it shall work with any Flash chip. If there is another Flash chip in use let me know and I will add support for that.
