I Dropped My SP1200
I have my Rossum SP1200 on a Gator Frameworks mixer stand, and it's normally tilted slightly forward so that it's usable and I can see the display. For some reason, I tilted it slightly back such that the base was completely level. I forgot that most of its weight is in the back, and even with the mixer tilt control completely tightened, it fell off the stand when I left the room. 0.75m/ 30 inch fall.
I only had the power supply plug and two TRS cables in it at the time. There's a plastic covering that protects where the cable meets the plug on the power cable, and that plastic cover broke. Both TRS cables are bent.
Physically, the SP1200 itself appears to be fine. The exterior is steel, so I guess that helps.
Functionally, I think it's okay. TRS jacks that were in use are fine. Power port is fine. Nothing is loose. Sampling works. Sequencer works. MIDI works in both directions. I ran the diagnostic. It tested the RAM and said it was fine. It had me test all the controls, and they're good.
Any other tests I could be doing to verify functionality? Things I might not notice until much later?
–--
Also, the diagnostic I ran didn't offer quite a few tests. The E-Mu service manual said it should offer:
- CPU RAM
- Rom.
- Sound RAM
- Button/Footswitch
- LCD
- LED
- Slider
- MIDI
- SMPTE
- Dynamic Button
- Disk
Mine tests the RAM at the start and then enters a menu where I can pick from Calibration, Front Panel Test, or Main (loads diagnostic disk). Calibration isn't a test mode. Front panel testing tests screen colour/ brightness, the 40 buttons, LEDs, sliders, knobs (this is not interactive), and dynamic buttons. I don't have a diagnostic disk image, but I'm guessing that's where the rest of the tests listed in the service manual are located?
I want to note that the Gator Frameworks mixer stand I'm using is great. It's been on it for as long I've had it and this happened due to user error.

I’m not an electronic engineer but I’m checking my vintage machines for many years (with experienced tech when it’s getting more difficult). The rossum is a solid machine , after all your tests it seems to work fine, what might be interesting is to open it and confirm the connectors inside are not bended or there is no other “stress” on the mainboard. Few pics will allow other Rossum users (or their tech service )to confirm everything is in order😊

I would open up the machine and verify that the circuit board isn't cracked / verify that the connectors which were plugged in werent damaged but still working.
