A friend of mine accidentally made a bit of a mistake with his Ami; switched his parallel port switchbox without powering down first. Now nothing will print to the printer and PerfectSound won't receive any signal in the port at all. Judging by the posts I've seen in c.s.a in the past, I believe he might have blown one or both of the 8520 chips (is that the right number?) So the questions are: 1) How do we verify they are the dead components in question? 2) How hard are they to replace? Socketed? (please say they are) 3) Any recommendations on where to get them? Thanks for any help. :-) Kurt -- ----------------------------------------------------------------------- || Kurt Tappe (215) 363-9485 || Amigas, Macs, IBM's, C-64's, NeXTs, || || 184 W.

Swap the two 8520s. If the modem stops working, one of them is bad. >2) How hard are they to replace? Socketed? (please say they are) They are socketed. >3) Any recommendations on where to get them? Through a dealer. They are Commodore designed/made chips, and not available in general parts places. -larry -- The only things to survive a nuclear war will be cockroaches and IBM PCs. +-----------------------------------------------------------------------+ | // Larry Phillips | | \X/ lphillips@lpami.wimsey.bc.ca -or- uunet!van-bc!lpami!lphillips | | COMPUSERVE: 76703,4322 -or- 76703.4322@compuserve.com | +-----------------------------------------------------------------------+
