....... but perhaps somebody has use for this info.
Almost all the NIC's (part # 4625-161) for the Pi-3502 and Pi-5501 controller for the old Minolta Di-200/251/351 and Di-450/550 are dead in the mean time.
The problem starts with slow printing and eventually there will be no communication at all between the network and the machine. The NIC is not being available anymore since ages from Minolta and therefore all machines had to be replaced over the years. However, we still have around about 10 rental machines of the Di 351 and Di 450 series, some of them with extremely low meter counts on it, which I do not like to replace for several commercial reasons.
Since long I had the feeling that the problem might be caused by rotten capacitors as in so much electronic equipment these days because of the typical pattern of sometimes functioning, sometimes not and sometimes only, if at all, after a long time being under power.
Since I was bored by my wife anyway today and had nothing better to do,
I replaced all electrolytic capacitors of a totally dead NIC and indeed it came to life again working very fast.
Perhaps somebody can use this information to his advantage.
