Super MAGICOM Card - SNES Interface . By The Vortex. May-2018

Several years ago I bought 8 of these PCB's, all in one box, just piled on top of each other. I got them solely for the EPROM's to re-purpose them, but I did not want to Erase the EPROMs until I knew what this thing did.

12 years later, it is 2018, and I got a SNES Super Wild Card and when I opened it up, its PCB is very similar to this MAGICOM PCB, and then is when I realised what I had & what is for.

REBUILDING THE SUPER MAGICOM CARD.

After Looking at what a Complete Super MAGICOM Card should look like , I realised that I was missing several parts, SO I did not have anything close to a working Device.

MISSING PARTS:

- 3.5" Floppy Drive

- 34 Pin Floppy Drive IDC Cable.

- Cartridge Port Card. (That connects the Super Magicom to the SNES Cartridge port)

- 12v DC Power Supply for the Floppy Drive (Because the SNES & MAGICOM do not provide enough current to properly power the Floppy Drive.)

- 16 MBit RAM card.

FLOPPY DRIVE

The Floppy Drive is the same type that is used in any IBM PC & compatables. Device Jumper set to DS1. (If you have any problems, Check to make sure it is set DS1 ) .

The 34 Pin cable is a Straight Through type, so you need to Remove the 34 pin IDC plug, Remove the twist in the Cable & then reconnect the 34 pin IDC plug.

CARTRIDGE PORT CARD

The Cartridge Port Card, you will need to make a replacement Card or purchase one from a company that makes prototype PCB's in small quantaties.

12v POWER SUPPLY

The 12v DC - 1 Amp, Power Supply can easily be obtained from any Electronic shop or from ebay.

The Super MAGICOM does supply 5v DC & GND for the Floppy Drive but you also need to connect 12v DC & GND to the FLoppy Drive for the spin motor.

Here is what the wiring should look like:

RED Wire = 5v DC (From MAGICOM PCB)

BLACK Wire = GND (From MAGICOM PCB)

BLACK Wire = GND (From External 12v DC Power supply)

YELLOW Wire = 12v DC (From External 12v DC Power supply)

 

RAM CARD.

After much searching on the Net, I noticed they Supplied 3 types of RAM card with these units:

16 MegaBit, 24 MegaBit, & 32 MegaBit.

Below is a Picture of a 16 MegaBit Card.

I noticed that the 16 MegaBit RAM Card uses 4 x KM44C1000AJ-7.

After looking at the Datasheet for this chip, I noticed that it is a Samsung 1MB x 4MBit Chip, and it has the same number of pins ,(20 pins), as the 4 x Empty IC Footprints, on the Super MAGICOM Card, in the top left corner.

Adding 16 MBits of RAM Directly to the PCB.

So I purchased 4 x KM44C1000AJ-7 chips and soldered them directly onto the 4 Empty spaces, in the top left corner of the PCB.

When I turned it on, it Reports SRAM = 16MBits , DRAM = 256k . So it works 100% without any changes to the Firmware.

If you get anxious and turn it on with only 3 RAM chips soldered on, you will see it Reports :

SRAM = 0 MBits.

YOU MUST HAVE ALL 4 x RAM CHIPS SOLDERED IN PROPERLY or you get NOTHING !!.

Here is my PCB after soldering on 4 x RAM chips.

ACTUAL GAME ROM SIZES vs LOADING SIZES.

512K GAME = 64 BLOCKS

1024K GAME = 128 BLOCKS (1MB)

1536K GAME = 128 BLOCKS (1.5MB)

2048K GAME = 256 BLOCKS (2MB)

Because a PC 3.5" Floppy Drive only holds 1.44MB, Games that are larger than 1MB will need to be split into 2 or 4 ROM files and copied to several floppy disks. unless you have a HD Drive like a 2.88MB Floppy.

The Super Magicom plus can handle all PC Floppy drive capacities from 720K up to 2.88MB.

Super MAGICOM Plus - ACTUAL RAM / Memeory sizes

As usual the Labelling on these units is Misleading. Only Mentally ill people use Megabits (Mb) as a counting system, It is like use Millimeters (mm) to measure a Highway instead of Kilometers (Km).

It should be Labelled with the Memory in Megabytes (MB). So now lets looks at the true memory sizes:

The 16Mb Super Magicom plus is acutally (1MB - 4bit RAM chip x 4 ) / (16bit CPU) = 1 MB

The 24Mb Super Magicom plus is acutally (1MB - 4bit RAM chip x 6 ) / (16bit CPU) = 1.5 MB

The 32Mb Super Magicom plus is acutally (1MB - 4bit RAM chip x 8) / (16bit CPU) = 2 MB
