I have recently had the following problems (3b1, 67m, vers.3.51): First my floppy started giving intermittent read/write problems. Next my hard disc refused to boot. I replaced the power supply and all seemed ok for a while. Then I started getting intermittent floppy read/write errors again. I tried swapping out the floppy drive and all seemed ok at first but the read/write errors started again. I found that the floppy would read 3 or 4 discs, and then start giving errors. I could leave the floppy alone for a few hours and then it would read or write 3 or 4 discs and then start giving errors again. I assumed it was a heat problem with the heat generated from the floppy drive motor. I have only one fan on the power supply side. So I tried swapping out the socketed WD2797 floppy controller chip with one from a 7300. The same problems persist. I am at a loss as to what to try next. I will certainly appreciate any suggestions. I did think I might add a fan on the floppy disc side. Otherwise I don't know what to do except sent it off to whoever it is in California that works on this machine. I do have the error messages from /usr/adm/unix.log but don't know what they mean. Thanks in advance for any help. W. S. Mahavier wsm@mathcs.emory.edu ....gatech!emory!wsm Emory University
