Not really that interesting but today I got asked "you used to do Norstar, didn't you??" So I said ok and got sent to a customer with a 616 installed in 1991 with a Startalk mini (probably added a bit later)... I don't think I've touched one those for 12+ years!! It was actually quite nice to work on one again and tbh I'd forgotten completly all the statalk setup but was surprised to find I remembered all the Norstar stuff. I really miss those days!
