[unix-pc.general] Trouble in paradise

trw@usna.NAVY.MIL (tsmith <trw@usna>) (03/25/90)

Well, a small disaster has occured.  I shutdown my 7300 last night to
prepare for an upgrade from 2.0 to 3.5 and when I turned the power back
on, nothing.  The screen come on with a typical pattern but there is no
disk activity (hard or floppy) and the machine just sits there looking
dumb.  I checked the LEDs and the green one lights but there is no other
activity.

Anybody have any idea what I should be looking for???
I have another machine to use in the meantime but I would really like
to get this one working again as I have put a lot of software on it.

At the same time could someone tell me if anyone has looked into replacing
the 64K memory chips with 256K chips? I seem to remember that the only real
difference in the chips is pin 1 (on 64K chips it is NC and on 256K chips
it is A8.)  It would be nice if I could put 2MEG on the motherboard.  And
maybe even on the expansion board as well.

One more question before I go back and stare at my poor 7300.  If I can't 
revive my dead machine, is there any way I can use the expansion memory
in my other machine (making it 1 1/2MEG)?? And what about putting a second 
disk drive on it?  I have a case and power supply I could use to house it
externally but can I hook it up somehow??

Thanks for any help anyone can provide.
