One hell of a restoration project... (cont') . Preparating one small PCB that should make things much better... hopefully! . 😊😊😊 . #SequentialCircuits #SequentialCircuitsInc #SCI #Prophet5 #SequentialCircuitsProphet5 #SCIProphet5 #Prophet5Rev1 #VintageAnalogSynthesizer #AnalogSynthesizerRestoration #VintageElectronics #Restoration #Repair #JohanDalgaard #StudioPiscineATokyo #TheGoodDoctorPrager

One hell of a restoration project... (cont') . Fresh-new J-wires have been put into place after soldering onto the keyboard PCB. Of course, all eight bus bars have been cleaned thoroughly one by one, as well as the J-wires' plastic holders. . Next step in the keyboard restoration process will be the last one, actually: screwing back the cleaned key tops onto their respective key support 😉 . #SequentialCircuits #SequentialCircuitsInc #SCI #Prophet5 #SequentialCircuitsProphet5 #SCIProphet5 #Prophet5Rev1 #VintageAnalogSynthesizer #AnalogSynthesizerRestoration #VintageElectronics #Restoration #Repair #JohanDalgaard #StudioPiscineATokyo #TheGoodDoctorPrager

One hell of a restoration project... (cont') Very first tests after intial power-on (and before I receive blank, NOS 2708 EPROMs to burn the P-5 Rev1 software on), and after having corrected some minor issues like a reverse-installed op-amp (😡), as well as a logic chip that wasn't receiving its +5V supply because of a cut track... ...HURRAY!!! I've all the supply rails present, and I also have got a clock for the CPU to run with! Makes for a good start I guess 😊😊😊☺️☺️☺️ Can't wait for ressucitating the (front panel functionalities of) the Prophet!!! ;-) #SequentialCircuits #SCI #Prophet5 #SequentialCircuitsProphet5 #SCIProphet5 #Prophet5Rev1 #VintageAnalogSynthesizer #AnalogSynthesizerRestoration #VintageElectronics #Restoration #Repair #JohanDalgaard #StudioPiscineATokyo #TheGoodDoctorPrager

One hell of a restoration project... (cont') Now let's get this Prophet-5 Rev1 front panel BLACK and WHITE... again!!! ;-) #SequentialCircuits #SCI #Prophet5 #SequentialCircuitsProphet5 #SCIProphet5 #Prophet5Rev1 #VintageAnalogSynthesizer #AnalogSynthesizerRestoration #VintageElectronics #Restoration #Repair #JohanDalgaard #StudioPiscineATokyo #TheGoodDoctorPrager

One hell of a restoration project... (cont') CPU & Memory sections of the CPU board are now ready to host the (forthcoming, NOS) eight memory chips, two 2708 EPROMs, and two MC14503 bus drivers ;-) #SequentialCircuits #SCI #Prophet5 #SequentialCircuitsProphet5 #SCIProphet5 #Prophet5Rev1 #VintageAnalogSynthesizer #AnalogSynthesizerRestoration #VintageElectronics #Restoration #Repair #JohanDalgaard #StudioPiscineATokyo #TheGoodDoctorPrager

One hell of a restoration project... (cont') Both Control Panels in preparation for a thorough clean-up ;-) #SequentialCircuits #SCI #Prophet5 #SequentialCircuitsProphet5 #SCIProphet5 #Prophet5Rev1 #VintageAnalogSynthesizer #AnalogSynthesizerRestoration #VintageElectronics #Restoration #Repair #JohanDalgaard #StudioPiscineATokyo #TheGoodDoctorPrager

One hell of a restoration project... (cont') CPU board free of any mods, free of old and ageing IC sockets, as well as corroded Molex connectors... and now finally cleaned-up. Let's keep on ressucitating the Prophet! Slowly but surely, anyway... ;-) #SequentialCircuits #SCI #Prophet5 #SequentialCircuitsProphet5 #SCIProphet5 #Prophet5Rev1 #VintageAnalogSynthesizer #AnalogSynthesizerRestoration #VintageElectronics #Restoration #Repair #JohanDalgaard #StudioPiscineATokyo #TheGoodDoctorPrager
