Description:
Hello Synth Lovers!With great acceptance of the card we have a NEW DESIGN !!! As our appreciation of business every card purchased will include an exclusive case to protect for whatever occasion you want to take it. Or simply from dust over time to keep card sitting when you remove from your Roland!This card original circuit was fully developed by DoJoe - J. Fenkes and with the great community of keyboard lovers. HALG modified the mechanical, the circuit, and incorporated couple important changes:✔ The 3 main slide switches that are on the back of the card are stronger now;✔ The components placement are fully located inside of plastic cover to protect against ESD (electrostatic discharge)✔ A card enclosure was designed to protect the card when you need to carry around✔ A plastic case now fits perfectly to cover components and switches; ✔ Label and serial number controlThis memory card isa replacement for Roland’s M-128, M-256 and M-512 cards, as well as the electricallycompatible Akai BR-16 and BR-32 cards. Compared to the original cards, thiscard has two advantages:✔ It does not requirea backup battery. It uses magnetoresistive RAM for storage rather thanregular static RAM,which is a type of RAM that can typically keep its data for twenty yearsbefore it needs tobe refreshed.✔ A single cardactually stores 16 M-128 / M-256 cards or 8 M-512cards, which can beaccessed by a pairof convenient switch slidersat the rear end of the card.✔ Like the originalcard, it also comes with a write protect switch.Installation:To insert the cardinto the card slot, the side with the electroniccomponents should face upwards (the sameway the side with the arrow would go on anoriginal card).Configuration:Whether your card isa 16x256 or 8x512 card is determined by asolder jumper on the card, marked JP1 on thecircuit board. It‘s the one circled in green inthe image to the right. The jumper consistsof three gold pads, two of which are connected by a small blob of solder. Ifthe left two pads areconnected, the card is an 8x512 card, if the right two pads are connected thecard is a 16x256 card. Theremight be solder on all three pads so no pad is obviously golden – just look whether the bigsolder blob sits to the left or to the right.This card comes configured 16 x 256K MRAMWith the plastic case is perfect for Roland D-50, but you can easily remove the plastic if you desire to fit in other keyboards. CompatibilityList:While the carddesign is as close to the original cards as possible, there is a small numberof devices that is not yetcompatible with our replacement cards.Tested and fully compatible: Roland A-90, D-5, D-50, D-550, D-10, D-110, D-70, U-20,JD-800, JD-990,JV-880, JV-1000, JV-1080, JV-2080, R-880 (GC-8), R-8M, GR-1, GR-50,PM-16, TR-626, AkaiMX-1000, VX600.Mostly compatible: Roland TD-10, TD-20. The card reportedly has errors wheninserted allthe way, but pulledback 1/8th of an inch it works fine.Not compatible: Roland VG-8, Peavey Tubefex.Someunits like the Roland U-110 and U-220 only accept ROM cards, not RAM cards.Changing thebank size beyond 512 KBitIf you‘d like theMRAM card to emulate PCM ROM cards or a GC-8 system ROM, you can do thatby increasing thebank size. The card supports the following bank configurations:16x256: The ABCD and 1234 switches work as usual. Pre-configured as this one. 8x512: ABCD works as usual, 1+2 and 3+4 select the samebank.4x1024: ABCD selects between four banks, 1234 is unused.2x2048: A+B and C+D select the same bank, 1234 is unused.1x4096: One bank of 4 MBits only, the switches have noeffect.There are markingsaround JP1..JP4 on the card, showing how to set the jumpers for a givenbank size. Find the line(s) corresponding to your desired bank sizeand set all jumpers touched by the line to the side that line is on. Forexample, to make a 4x1M card, JP1 and JP2 would go to the left position,JP3 and JP4 would go to the right position, as shown in the image to theright. JP6 usually does notneed to be changed, except if you‘d like a 1x4096 card, in which caseit must be changed to the left position.As a quick hint your card has several banks of memory blank yet. By the very first time the keyboard access that bank, you might see on screen "Illegal Card", but just ignore it and continue with your process. Once the bank is used and has patches on it, you no longer see that message.YOU will receive 1 card configured to be 16 x 256K MRAM + 1 exclusive case ready to be used as you see on the picture + Manual.Board size is 3.78L in x 2.13W x 0.078 in - Plastic cover is 4.13L x 2.49W x 0.665HCard is pre configured with Roland D-50 All original cards already pre loaded from 00-04, then you have all rest of the banks ready to be used, but you can also reuse the banks where we saved the original cards.The Original cards are saved on banks: A1 -> Card 00A2 -> Card 01A3 -> Card 02A4 -> Card 03B1 -> Card 04B2 -> Surprise!This card is fully functional and 100% tested!Bid with confidence Non Return ACCEPTED!
