Arcanis-Will Posted February 24, 2014 Share Posted February 24, 2014 I was testing an 810 drive yesterday and initially I thought it was broken. I had the slide switches set for drive ID 3 and it was not responding. But I decided to test all drive IDs and I found that the drive always thinks it is drive 1. Using it as drive 1 seems to work ok. I was able to make a boot floppy and save/load some test files. Has anyone else seen this? If I clean the switches will it fix the problem? Or are there other fixes I should perform like maybe installing new switches? Quote Link to comment Share on other sites More sharing options...
Rybags Posted February 24, 2014 Share Posted February 24, 2014 Can't say I've seen or heard of it. Plenty would just set an ID and it might stay on that for years. Might be just dirty contacts on the switches - you could try sliding back/forth 20-30 times and it might make a difference. Quote Link to comment Share on other sites More sharing options...
Bryan Posted February 24, 2014 Share Posted February 24, 2014 Try a different 6532. 2 of the IO pins go to the switches. Quote Link to comment Share on other sites More sharing options...
Arcanis-Will Posted February 24, 2014 Author Share Posted February 24, 2014 Try a different 6532. 2 of the IO pins go to the switches. Might be just dirty contacts on the switches I just found the 810 Field Service Manual online. Thanks for the tips - the schematic for the switch positions shows they are read by the 6532, and also that one of the valid positions for each switch is open-circuit. So a set of dirty contacts probably manifests as the open position for both switches. It would make sense for the drive's default ID to be 1 in the case of switch failure or stuck open. Since the drive appears to otherwise work, I think it's more likely to be a dirty switch contact. I will try cleaning it and then check the switch operation with a multimeter. Thanks for the suggestions! Quote Link to comment Share on other sites More sharing options...
