    Well, now it may be a bit out of alignment. Without fancy test equipment, the first thing you should do is run ImageDisk, start "alignment mode", insert a known good factory-created write protected...

    This is a fairly straightforward fault. There are only a hand full of components between the direction input and the motor. A schematic is on bitsavers:...

    Did you try this with a different cable?

    The floppy interface has one pin specifically for step "direction". Either your cable has developed a fault, or the input on this pin has become faulty.

    I don't know about that bag, but I have seen in a couple of computers where easily replaceable screws, backplates, and mounting hardware rusted first and almost everything else still looked fine. If...

    No. I'm fairly sure PCI does not allow access to the required I/O ports and interrupt either. Even if they did, they would need to add BIOS support, since a machine without PS/2 hardware would...

    It also just occurred to me that installing WinImage 6.1 on the original release of Windows 95 requires an updated COMCTL32.DLL, and its setup program does not tell you that.

    DR/Caldera "diskcopy", like so many other DOS based disk copiers, only supports their own proprietary format. They just happen to use the same file extension. Most IMG files out there are "raw sector...

    Worn out cables. And more broken cables. All those f-ed up cables! Try it with the wind blowing from the south and they don't work. I don't know, it might just be me.

    I use WinImage 6.1 under Windows 95 all the time and have no problems.

    If something is borked inside Windows, other windows based tools might give you problems, so you might consider a DOS based...

    The drive light staying on constantly is usually a cabling issue and often happens if a plug on the cable is attached upside down.

    The drives not coming on at all with the other cable also...

    The colors were not any kind of code. 5.25" and 3.5" disks came in all kinds of colors.

    Sony's blue might have come about, in part, to call attention to the rigid nature of the case. I seem to...

    That's not a 5150 clone is it? The slot spacing looks more like an XT, but with fewer slots. Can't quite read the name on there.

    What is that out of?

    Let me guess, a tantalum capacitor off the -12 or +12 line. Those things love to go boom.

    Just cut it off and try again. Those are there for stability purposes and will run without, although they...

    Very nice system. If it were me, I'd probably sanity test the power connector with a volt/ohm meter to make sure things more or less match up, although it sounds like it should work.

    8/14/84 would be IBM PC-DOS 3.00.

    Really, I would recommend just updating to at least IBM PC-DOS 3.3.

    The best way to update the system would be to get Norton Utilities 4.5 (4.5 is the best...

    If it is in good cosmetic condition (no yellowing, rusting, or burn in) and complete, then I'd expect it to at least sell for a few bucks. I think in this case I'd at least turn it on and see if it...

    A problem is that different IDE devices may interpret a CF card's geometry differently. Even different XT IDE BIOS revisions can wind up expecting different CHS values.

    The CHS values set in the...

    If you can dump a copy (it should be possible to dump it from DOS, without an EPROM reader/burner) you should send a copy to user Modem7 for possible inclusion on www.minuszerodegrees.net

    Very nice. That looks like it has everything except the UCSD Pascal Compiler package. But unless I'm mistaken, the UCSD_IV_3_PASCAL.IMA on the z80 site is the UCSD Pascal Compiler disk.

    I guess...
