RE: HP-65 - card reader with WB wave noisy - Help needed
Hi Alberto,
Not sure what "driveless" means A long shot maybe, but it was mentioned in a thread some time ago with a card reader not writing well. I think it was for a 67, but the same principal applies. There are capacitors across Vbsw and GND in the power supply. 15uF and 60uF, maybe changing one or both of these might help. cheers Tony |
