[sdiy] DIY Roland M-64C cartridge ?

[Tom Wiltshire]

Nice work finding that, Christian.

That looks simple enough. There isn't much inside it; the RAM, a  
backup cell + diode, SIL pull up resistor, bypass cap and a couple of  
other resistors and capacitors.

I did wonder at Roland making a different PCB for the M-16C version  
though, if the M-64C has an extra few pins on the RAM.
I'd have thought they'd be identical except for the larger RAM chip.  
Just goes to show that sometimes things aren't as straightforward as  
you think they should be!
