Mine is the same:
I know there has been several models with nicers GUIs and more formats supported. You can mostly find this device in Taiwan.
Can't recall my bios version and don't know if it can address more than 16M but there's the space to add 4 more memory chips.
The 46 pin connector is probably a cartridge port replication. Maybe to add DSP support or some other extra function.

When used with either NTSC or PAL you should need a boot cart, there's no internal CIC.
There are multiple hardware revisions, I think 3+.
There is a 24/32M version, but it was released significantly later. I have a 32M unit and I believe the BIOS is dated 1994/1995, it can load from FAT formatted disks.
Trace it out.
Many of them, until 1996 I guess. They probably aren't compatible across all hardware though.

Yes, I need to have a boot cart on my PAL SNES. But when I use it on my FC Twin SNES clone, I don't need a boot cart. I have never tried it on a NTSC SNES though.
My unit has BIOS 4.9B and can read FAT formatted disks, and can load SMC files from FAT. You can have 2 different SMC files on a floppy at once, and you can select the game you want to load with the pad. But 2 files is the maximum, and you cannot load multiple disk SMC games. You need to use ISC to write down games larger than one floppy. But it's still a nice feature that it can load and store multiple SMC files on a standard FAT floppy.
Does your unit looks the same as mine inside? If not, can you perhaps upload a picture of the pcb? I would love to see what the newer versions look like

You don't need a cart on the FC Twin because it doesn't have any lockout chip to unlock.
Yup, it looks the same. That's the "domestic" shell, there's also an export version with a more boxy look to match the NTSC SNES.
I'm curious myself about the PCB but it's in storage.

I picked one of these up today, 32M version, my PCB is different, this has to be the simplest copier, no menus or utilities, it is nice that I am able to format and drag and drop SMC files in windows though, I actually downloaded all the DOS utilities and transferred a game to disk that way the first time...
As mentioned earlier, no internal CIC, I have to boot-up with a cart in the slot at all times.

Please show us some pictures of the PCB

I just realized that this thing does not have a power supply jack, so it can only take it's power from the cart port, also, it was working fine at first, but now it intermittently will not boot up...

Thanks for the pictures. It looks the same on the outside, but things have happened inside indeed
What is the BIOS version on this unit? You see it on the screen when booted up.
Since it doesn't have the external PSU, it needs the internal battery to store the SRAM saves. The battery leaks like hell, so if you have not already changed your I would suggest you do that. The unit works without it too, but you will not beable to store the saves to disk.

It shows the same exact screen as posted by Mystic_Merlin minus the no drive message, I do not see the BIOS version.
How do you store the saves to disk?

It looks pretty much the same. They just adapted the pcb to newer standards at that time: the main logic chip is now a SMD and they chose different memory packages. But still no CIC onboard...
Just wondering why there's a new Xtal. Maybe the 16.000Mhz was not clocked well enough to match the newer chip?
Oh and I just noticed the empty spot near the 48c2100j...upgradable to 64M maybe.
EDITx10: lol...sorry for editing that reply a thousand times...ideas are popping every 5 secs. Actually this empty spot does not have enough lines for a memory package so it could be for a CIC.

Exactly 16 MHz is necessary for the floppy controller which will divide it down to a precise baud rate, but 16 MHz isn't spectacular for a DRAM state machine. Because the external clock isn't aligned to the CPU the circuit has to be designed so the logic to miss one whole clock cycle. Since they aren't in phase it will happen very often. Perhaps the slight increase in speed was enough to make it work reliably.

It's not for a CIC either (16 pins), it looks like it's for a small 74 series chip.

Indeed I noticed it was missing 2 pins but if I remember correctly most CIC on copiers have 4-5(?) lines connected (VCC, GND, DATA IN, DATA OUT, CLOCK). I know, it's a little twisted: missing pins, pin 8 should be connected...
More reasonably I guess you could connect a CIC to the port replicator

Posted: Mon Feb 28, 2011 2:50 am Post subject: Sram menu |
|
|
For those who don't know how to do get to the Sram menu.
After turning the console off with a disk inserted, hold down select while turning the console back on.
Normally if you have anything other than the first disk inserted it will give you the wrong disk prompt, here you can also press select to bring up the Sram menu. It won't bring it up without a disk inserted.
For some reason, holding down A on the second controller while turning the console on fills the screen with Hex characters...
Does anyone have the manual for this? Quick search turned up nothing, I'm sure there's not a whole lot to it, but it would be nice to check out.

Thanks for the info! I would also like to see a manual for the unit.
