This memory card is a replacement for Roland’s M-128, M-256 and M-512 cards, as well as the electrically compatible Akai BR-16 and BR-32 cards. Compared to the original cards, this card has two advantages:
✔ It does not require
a backup battery. It uses magnetoresistive RAM for storage rather than
regular static RAM,
which is a type of RAM that can typically keep its data for twenty years
before it needs to
be refreshed.
✔ A single card
actually stores 16 M-128 / M-256 cards or 8 M-512
cards, which can be
accessed by a pair
of convenient switch sliders
at the rear end of the card.
✔ Like the original
card, it also comes with a write protect switch.

Compatibility
List:
While the card design is as close to the original cards as possible, there is a small number of devices that is not yet compatible with our replacement cards. The card will also fit on those keyboards/modules below.
Tested and fully compatible: Roland JD-800, JD-990, JV-880, R-880 (GC-8), R-8M, GR-1, GR-50, PM-16, TR-626, Akai MX-1000, VX600.
Mostly compatible: Roland TD-10, TD-20. The card reportedly has errors when
inserted all
the way, but pulled
back 1/8th of an inch it works fine.
Not compatible: Roland VG-8, Peavey Tubefex.
Some units like the Roland U-110 and U-220 only accept ROM cards, not RAM cards.
Changing the
bank size beyond 512 KBit
If you‘d like the
MRAM card to emulate PCM ROM cards or a GC-8 system ROM, you can do that
by increasing the
bank size. The card supports the following bank configurations:
There are markings around JP1..JP4 on the card, showing how to set the jumpers for a given bank size. Find the line(s) corresponding to your desired bank size and set all jumpers touched by the line to the side that line is on. For example, 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 the right. JP6 usually does not need to be changed, except if you‘d like a 1x4096 card, in which case it 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 to Format it. Once the bank is formatted you no longer will see those messages.
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 0.063 in - Plastic cover is 0.55L x 2.31W x 0.502H
The card must be Formatted before using it on your keyboard/Module!
On JD-800 the card cover needs to be removed to fit on card slot due to the
card slot deep length.
This card is fully functional and 100% tested!
