[comp.sys.amiga.hardware] Does my machine need repair?

johnm@spudge.UUCP (John Munsch) (12/22/90)

A few months ago I tried to plug a printer cable (with an Apple Imagewriter
on the other end) into my Amiga 2000.  I did it with the machine on because I
unplug/plug stuff from/to my serial and parallel ports on my PC/AT clones at
work all the time without problems.  With the Amiga this is apparently not a
good idea.  I saw a 1/4" long spark between the cable and connector and then
the machine rebooted.

However, I was still able to print to my CGP-220 printer and capture sound
using a friend's Perfect Sound audio digitizer.  I figured it was OK.  Until
last night, when my new DigiView (which works fine on a friend's 2000)
refuses to digitize ANYTHING on mine.  If I try to get a histogram it shows
NO samples at all.  If I try to digitize it HANGS MY MACHINE!  I checked the
signal being fed to it from my color splitter and it appeared to be a perfectly
normal grayscale picture.

My question:
	Is it possible for me to have damaged my parallel port in such a
	way that DigiView will not work but still be able to print and
	digitize using Perfect Sound?

I don't know, John.. but...
I had a problem once where I could print on my Star SG-10 printer, my Canon
PJ-1080A (same as Radio Smack's CGP-220), and digitize with Perfect Sound 3.0,
but I could not communicate with ParNet.  The problem was a bad parallel port in
my Amiga 1000 (that I am guessing I created by plugging in/out my Perfect Sound
digitizer V[1-2].? .. :-) )

It could very well be your parallel port (IMHO.)
