I used to own a semi-functional “Univox Organizer” which was made by Crumar (all the B keys were not working, I could not figure out what the issue was because the thing weighed 50-60lbs and there was no technical manual available back then.) I sold it “as-is” to someone I hope had better luck.)
just moved into an old apartment and the intercom had a farfisa logo which i was not expecting! i immediately regretted telling the landlord that they made great organs. blank look ahaha
