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. bill gunshannon trw@cad.usna.mil 720wfg@scrvmsys.bitnet bill@platypus.uofs.edu (They are all valid addresses to reach me. Of course, there used to be mordor!bill@platypus.uofs.edu, but he's not feeling well at the moment. :-( :-( :-( )
