UPDATE: All units have now been sold, the last one remaining is boxed but has a missing BIOS chip. I can sell this one for GBP£30.
A standard FFE Super Wild Card DX programmed BIOS should work fine in its place, although you'd be on your own here.

Also if anyone wants any photographs of the innards let me know and I will post them here.

I'm interested in PCB pics.

Thanks, very interesting stuff! Most components aren't socketed but everything is well documented on the PCB, nice.

I never owned an original DX but I don't recall there was a reset switch?
Also, I like this custom PCB bridge to move the FDD forward.

For the U10, I'm assuming the same
Regarding the jumpers, that's a total random guess but based on the Super Wildcard I would say you'd have to move 3-4 to 1-2, 7-8 to 5-6, 11-12 to 9-10 to set the copier in PAL. Since I believe the DX has a user settings SRAM maybe moving 13-14 and 17-18 would clear it?

I would gladly spend those 30 GBP on it but I don't have a EPROM burner, maybe one these days...

Hi, thanks for the info. One of my customers is currently doing some testing so I will pass on the information and see what the outcome will be. It seems that from the current order of:

0 1 0 1 0 1 1 0 1 0
the following are critical to NTSC operation:
0 1 0 1 0 1 0 0 0 0
so your suggestion for PAL operation would be:
1 0 1 0 1 0 ? 0 ? 0
....with some option for SRAM for 13-14 and 17-18 (trial and error).

0= no vertical jumper
1= vertical jumper
?= not sure

Here I attached a pic of my PAL Super Wildcard (works flawless on a Japanese SFC with a Jap cart in). As you can see, the jumpers are moved following this scheme:101010 ; so it make sense that for your DX from 1-12 it should be the same.

The CIC is PAL

Regarding 13-20 that's a total random guess of mine that it should concern user settings reset. Following the same logic
1010 = standard
0101 = reset

Your best option is still to wait for kyuusaku's input

PS: I mentioned "SRAM" before as a type of memory for saving the BIOS' settings, I'm not talking about the SRAM used to save games' settings.

Excellent , thanks for the photo as well. I've yet to get hold of a PAL CIC, but I think I might have an old FIFA soccer cart lying around somewhere, so I can pull the PAL CIC from that (it probably has a D413A).

Yes we will wait to see what kyuusaku says also. I'm wondering now if it might be possible to make a PAL/NTSC compatible version by using a very long switch, so that both CIC and jumpers can be changed with one action

Damn, very nice pics. I think as I said before never seen this version. Looks VERY well built too.

The reset button could be a hack for the parallel port, I think it can get stuck in a bad state after a transfer or if the transfer is interrupted.

As for AC in, yeah, DB1 = diode bridge. Many copiers will have a protection diode, but won't rectify AC. The FFE DX might have had this too, I dunno.

The thing is definitely licensed since it has FFE's ASIC, almost everything is exactly the same as the original, if it isn't entirely. The layout and better Japanese components are nice, but I dunno if I'd say it's on par with big electronics of the time (Sega Saturn?), by 1994 everything was SMT and designed for high frequency (not that it's really needed for SFC). If anyone Bung was closer.

(Mystic_Merlin: User settings are in the serial EEPROM.)

UPDATE: The remaining unit (missing the BIOS chip) has now been sold, so there's currently no more units left.
