Do It Yourself Akai MPC60 Memory Upgrade
For under $20 in parts (and 2-3 hours of your time) you can max out the RAM in your Akai MPC-60. The following parts are available from Jameco and other electronics suppliers:
- (6) 514256 80ns DRAM ICs [20 pin DIP package] ~ $2.50/ea
- (6) 20 pin DIP IC sockets ~ $.60/ea
Remove the voice board from the MPC60 then perform the following steps:
- Desolder the six 514256 DRAM ICs installed on the voice board.
- Install IC sockets.
- Bend pins 3 and 16 on the new DRAM ICs outward at a 45 degree angle.
- Solder the new DRAM ICs on top of the old DRAM ICs leaving pins 3 and 16 unconnected.
- Install new double stacked DRAM ICs into sockets.
- Connect pin 3 (WE) of all three top DRAM ICs in the left most bank together and to pin 2 of the adjacent 48 pin euro socket.
- Connect pin 16 (OE) of all three top DRAM ICs in the left most bank together and to pin 5 of the adjacent 48 pin euro socket.
- Connect pin 3 (WE) of all three top DRAM ICs in the right most bank together and to pin 10 of the adjacent 48 pin euro socket.
- Connect pin 16 (OE) of all three top DRAM ICs in the right most bank together and to pin 11 of the adjacent 48 pin euro socket.
Reinstall the voice board, boot up the unit, go to Sounds then Sample new sound and verify maximum sample time is now 26.2 seconds.
