Super MAGICOM Card - SNES Interface . By The Vortex. OCTOBER-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 it 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.
- 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.
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)
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 in, you will see it Report :
SRAM = 0 MBits.
YOU MUST HAVE ALL 4 x RAM CHIPS SOLDERED IN PROPERLY or you get NOTHING !!
Also note a Capacitor was added as a decoupler, can also be found on old 30 pin SIMMs.
Here is my PCB after soldering on 4 x RAM chips.
MENU on Startup
This is what the normal Start Up Screen looks like.
See at the bottom it says 16Mbits DRAM and 256K SRAM. The SRAM holds values even after power off. The DRAM holds the actual game you Copied from Cartridge or LOADED from Disk. So now all you have to do is hit the SNES Reset Button and the game will stay there Forever , until you turn off the SNES at the wall.
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.
AVOID WANKERS WHO USE WIKIPEDIA RUBBISH like MiB, this measuring system Does not Exist any where in the world. Microsoft don't use it in Windows, Linux & Unix does not use it, Apple do not us it. WHAT MORE DO YOU NEED !!
It is simply FUD invented by Companies that want to rip you off, coz 16Mib sounds alot Bigger than 2 MB.
I ask you, Does 1 + 1 =2 ?, American Companies will lie to you and tell you 1 + 1 =3 if you LET THEM !!!
AVOID WIKIPEDIA and its DUMB LIES !!!! it is run by Companies like SONY & SEAGATE who love to edit it anytime they like, and love FUD & LIES !!! I would trust CHINA more than the USA these days.!!!
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
