HxC Floppy Emulator Rev B on Amiga

[TTD]

Hi,

I have an old Rev B of the HxC Floppy Emulator after I have repair a trace to SW1 and check other trace to the switches it seams finally to work as it should.

My question is how can I make save games floppies?
I have read that Rev B of it should have done some modification to support amiga save - that is excatly what I want to.
I have try on for instances to Sensible World of Soccer 96/97 version.

I know floppyname is SWOSU can I format it self without the modification of the rev B?
I have try create an empty disk, with HxCFloppyEmulator.exe software but it looks that is not working.

I don't understand what you are trying to do.
To save on Amiga : Rev C or Rev B + mod
To create an empty disk or save game : ADFOpus, WinUAE, HxCFloppyEmulator...

Ok then I don't understand how I can mod my Rev B board so I can do this
To save on Amiga : Rev C (I dont have C) or Rev B + mod - I do have Rev B but not mod or else how can I see the mod?

22/08/2010: Firmware SD HxCFloppyEmulator v1.3.0.0
- Amiga Write support added :

Note to the Revision B PCB owners :

To activate this new features you need to add a Microchip 23K256 SPI SRAM chip and 4 resistors.
The connection to do is :

23K256 pin 1 -> 220ohms resistor -> PIC18F4620 pin 22
23K256 pin 5 -> 220ohms resistor -> PIC18F4620 pin 27
23K256 pin 6 -> 220ohms resistor -> PIC18F4620 pin 28
23K256 pin 2 -> 220ohms resistor -> PIC18F4620 pin 29
23K256 pin 8 & 7 -> VCC3.3V (this voltage can be found at the capacitor under the sdcard connector or at the output of the regulator)
23K256 pin 4 -> GND
23K256 pin 3 -> Not connected.

(a 100nF capacitor is also recommended at the pin 8 of the 23K256)

Hi Jeff, thanks for the reply to mod the rev B of HxC, but GND signal from where, can I use it from the power connector from floppy (Black wire)?

The recommend 100nF capacitor what volt rating, can I use electrolytic or what kind should it be can I use non SMD components, if so which should it be?

Next problem, I got is where can I get the Microchip 23K256 SPI SRAM, is there others chip that does the same, and should it be a SMD or could other do?

The only think I got is 4 of 220 Ohms non SMD components. (If that is good eough)

Hope I can get some confirm my knowledge to electronic parts is very limited.

An electrolytic capacitor is fine, you need 3.3V or more. Doesn't need to be SMD.
GND on the power connector is ok, you can also find it at a lot other places.

It looks like 23K256 has a DIP (through hole) version that you can use.

So it shouldn't be too hard to solder all of this together...

Thanks alot pulkomandy for your reply, now I just want to try find that chip in my country.
