. . WOW WOW WOW!!!!!!!!!!!!!!!!!! Looks like @soundgasltd 's #Publison #InfernalMachine90 is FINALLY back to full work!!!!!!!!!!!!!! I AM SO RELIEVED!!!! βΊοΈβΊοΈβΊοΈβΊοΈ . SMPTE board is now fully working, AT LAST!!! ππππMain CPU recognizes the optional PCB, meaning that all SMPTE algorithms are accessible again. And the most beautiful cherry on the cake is that the remote control finally works normally, too!!!!!!!! ππππππππππππππππ . Thanks to the help of another huge Publison fan, @infernalemachine in Bordeaux (who VERY kindly lent me his own working unit so I could compare both units), I've been able to trace the issue to a rather "simple" fault... in itself: there had been a swap of two ICs on this previously non-working SMPTE card! πProblem is, as Publison never released ANY technical information about their machines, and as they used to sand off the part number on EVERY IC in their machines, it was almost impossible to guess which part had been swapped!!! . Anyway, please note that I got this far (that is, solving the most important issues in this IM90) WITHOUT any official schematic... Then I guess I could deserve some gratitude from Mr. Dean himself (the founder of Publison), couldn't I? βΊοΈβΊοΈβΊοΈ . So, thanks again to these friends for their MUCH appreciated help and support: @infernalemachine of course π @soundgasltd for their trust and confidence βΊοΈ and @watersoundpro for the highly spiritual support to my endeavours in repairing the wonderful early digital machines from Publison! πππππππ . #PublisonSystems #IM90 #InfernalMachine #PublisonInfernalMachine #PublisonIM90 #VintageDigitalFXBox #VintageDigitalMultiFXBox #FirstCommercialProAudioOutboardWithDSPs #SoundGasLtd #SoundGas #SoundGasUK #Repair #PiscineATokyo #StudioPiscineATokyo #TheGoodDoctorPrager #LeBonDocteurPrager https://www.instagram.com/p/Bud26Z_FWhx/?utm_source=ig_tumblr_share&igshid=3uscmrxavsik
