Hi all! :)
Today, I acquired a PC7300. Alas, the poor fellow
seems to have a rather large malady of some type. I've
never had much experience with these beasts before, so
much of what I say goes on the word of the last owner.
Evidently, before one of these machines first boots
up, it displays a few rectangular characters in the
upper left hand corner of the screen. It then proceeds
to its boot screen. (And then OS loading and whatnot
if all is well.) My machine just sits there and
displays rectangle after rectangle after rectangle. No
boot screen ever appears. The machine was working when
put away for storage when put away a few months ago,
but refused to boot when it came out. I guess that
leaves it at the point that I got it. :)
I managed, with a bit of yanking about, to get it
disassembled, down to the motherboard, as per the 3b1
FAQ. I got some of the big dust out and reseated all
of the seatable chips. There didn't seem to be any
major damage anywhere... one of the fans had a cut
line which I repaired, but there was no evidence of
any type of overheating. Most socketed chips were
reseated, everything was powered on once again, and
the same thing seems to happen. :( The rectangles
appear, the floppy drive sits and spins, and the hard
drive spins up and sits there. There is a loud
beep/click type sound, which I'd figured to be the
heads unparking themselves. When the hard drive cable
is removed, the machine freezes at one rectangle, so
was thinking it could be something along those lines.
Will see if I can dig up a HH ST-506 drive somewhere
soon. The power supply looked OK... one very slightly
mad looking / bulging cap, but nothing overtly broken.
(My DMM is in the mail at the moment, so I wasn't
really able to test much. :() The only other thing I
think I can report are that the four indicator LEDs
are at a constant on state - could also be normal for
this part of the boot cycle for this machine, too.
Any suggestions as to what is making this poor machine
act as it does would be very, very much appreciated.
:) Can't wait to get it running at some point... it
looks like such a nifty box.
Thanks kindly! :)
Andy
