It tells u the RAM on bootup and in OTHER -> INFO.
Well done with the maintenance.
Here's a couple of MPC3000's that I repaired, fixed up and added new pad sensors, all new tact switches, Vailixi, an internal SCSI Compact Flash card reader, max RAM and a new backlight.
https://www.facebook.com/media/set/?set ... 583&type=3I managed to get the original ALPS tacts but I'm sure there are Omrons out there that are just as good or better.
Saint_Baz is a fella local to me. Top bloke and knows his backlights so yes, good choice.
I also bought a new rotary encoder from mpc stuff but it turns out that I fixed the old one with some alcohol and then some switch lubricant.
Also, I prefer the action of the old, original pad sensors to the new mpcstuff ones.
The original pad sensors have a better dynamic range. You have to hit them harder for the higher velocities, whereas the new sensors... you just have to breathe on them and you're at full velocity. I hate that. I want to be able to hit my pads normally for full velocity, not tap them lightly.
I've kept the original pad sensors in my own personal MPC3000 for this reason, but I'm sure there are people out there that like the 'light-touch' sensors too.
Also, a tip; check the solder under the capacitors in the power supply and add a bit of fresh solder to them. I had dry joints on one capacitor in one of mine that caused the Mute Relay to sometimes not work on power-up, which meant that the audio wasn't switched-in. It would work fine for a week or so, then suddenly my audio wouldn't work one day... then it'd work again for a while! Glad when I finally fixed that issue.
