My PC6300 has been eating DMA's. I was getting parity errors however after swapping out memory chips the problem hasn't gone away. I removed the DMA controller chip ( 6M ), soldered in a dip socket and put in a new chip. This fixed the problem for awhile but now a DMA chip only last about 3 hours before it is fried. What is causing this problem? I have found a capisitor out of spec. C88 104pF. Who makes these? There are several resistors out of spec. R52, R53, R54, and R22 and R25. Are these responsible for frequent failure? Any help will be greatly appreciated. ---- Robert W. Somers 919-248-1494 somers@mcnc.org MCNC, 3021 Cornwallis Rd., RTP, NC, 27709-2889
