    Probably obvious, but I'd check the internal audio connectors. If it has been worked on before, it may not have been plugged back in correctly. If one has shorted to ground, then both might not work....

    I know we are talking about larger hard drives here, but for IDE drives less than 127GB (especially small ones that don't like IDE USB converters), I find MAXLLF to be quite useful. It does a...

    That is probably due to the drive overlay software. Those do funny things to the 640k base memory.

    Are you sure you need the drive overlay for this drive? 500MB may the BIOS limit on a 486, but...

    Just glancing at this thread...

    To reduce the variables at play, I would focus on writing a Tandy 2000 boot disk image with ImageDisk. Don't bother with other DOS tools, as they can have problems...

    What I sort of miss are the after crassmass sales at Microcenter. A long, long, long, time ago that would be the time you could get a good deal on machines that had been sold and returned. That was...

    First of all, I'd be suspicious of the system's health. Before tackling the hard drive, verify the rest of the machine is working with some diagnostics. Test RAM, CPU, floppy, video, etc. Also verify...

    Depends on the shape and size of the item, but sometimes I'll set clear bottles of water on the top of the item. Light can get through, but still move them around a bit periodically.

    Interesting the "videx clone - rom 1 - firmware - bottom row.bin" differs by one byte from the "Videx Videoterm ROM 2.4.bin" linked above.

    Also, the file videx firmware 600 1982 - bottom.bin is...

    I'm a little confused. Is the faulty card a clone or a genuine Videx card? The photo above looks like a genuine card. If the faulty card is a clone, then perhaps a photo of the actual card would...

    That looks fairly close to a Video 7 VEGA EGA card:

    55 AA at the beginning is the signature that lets the system BIOS know there is a BIOS extension there.

    The checksum is at the end of each BIOS extension.

  12. Entire row of TRS-80 Data Terminals seen on eBay

    Just something I saw on eBay, and seemed cool enough to mention: A row of four "TRS-80 Data Terminals". I believe these use the same cases as the TRS-80 Model III. Apparently these are being sold...

    It depends on the problem domain.

    A huge chunk of what people want is just business databases, and it has been possible for a long time to create a simple usable database application with just...

    You would have to ask a lawyer about what is illegal or not, and there are none of those here.

    One slight clarification though, "warez" typically refers to software that is still sold and/or...

    I'm really kicking myself for passing up an opportunity to get a bunch of used 50-pin SCSI drives at one of the previous VCFSE events a number of years ago. I remember when eBay was full of these...

    If you have a USB floppy drive, you SHOULD be able to write raw 1.44mb floppy disk images. On Windows, this is just a simple matter of loading up WinImage, or a similar tool. On Linux there is "dd". ...

    From what you describe, I think you may need BOTH.

    Like I said, this crap gets stuck in the jacket lining as well as on the disk surface.

    Perhaps post a photo of how it looks?

    A disk tester won't give you meaningful results if a title is copy protected.

    If that is a new picture, it still shows shorting, but only on one line. So you are going back and forth between having the two pins shorted and dead now.
