RAM expansion module designed to Sequential Circuits Prophet 2000 and Prophet 2002 samplers. This is a replica of the original SCI PC877 and it doubles the original memory from 256Kb to 512Kb. It doesn't seem much these days, but it makes a huge difference. Finding a original module is very hard and the prices are becoming absurd. I really wanted to have one, so I just made it and you can also have one because I made some extra PCBs.
The KIT includes 3 PCB spacers and screws.
It needs the firmware version 3.0 or newer in order to work properly. I can provide you the last firmware (4.3b, check my other items). If you buy both products together, I will give you a small discount.
