    On the Tandy 2000, what's the format parameter (DOS 2.11) to format a disk as 720K? By default it's only formatting as 360K. (/f:720 is not working)

    Thanks everyone! I was able to get it to work. To summarize for whoever else may ever need to do this:


    Use a more "modern" computer (like a 486 or Pentium) with a 5.25" 1.2MB floppy disk drive...

    The problem is that the Tandy 2000 uses "quad density" 720k disks in a 5.25" drive which isn't really standard.

  5. How to create Tandy 2000 disks on a PC with a 1.2MB drive

    Can I get some help with this? I've read it's possible to do this using ImageDisk. However I'm a bit unclear on what type of disks to use and the procedures for using ImageDisk. Has anyone...

    The thing was definitely out of alignment. I just returned it on eBay and ordered another one - works perfectly!

    Yeah as I expected, I can share disks between other systems, just not with the PCMCIA drive. Any pointers on realigning it?

    Here's a picture of it. Can these even be adjusted?

    I just got a Compaq PCMCIA floppy drive for my Contura Aero 4/25. I'm having a weird issue where I can't share floppies between machines. It is a 1.44 drive. From my Windows machine, I wrote some...

    Atari Portfolio - Stiff Lid Hinge

    I am the proud new owner of a fully working Atari Portfolio. I plan to use it to teach myself x86 assembly. (BTW, does anyone have any recommendations for an assembler that'll run well on it?)

    Seriously when do you think it'll be ready? I never did get that Micropolis drive working that you were helping me with. This'd at least get that system up & running.

    Will it support Micropolis/VG systems? If so that would be amazing! What's the plan, would it be a S-100 card with an SD card slot onboard? Or would it be an external device that interfaces to your...

    Cool so do you know of a half-height 360K drive you could recommend for my 486 that could write these disks? I don't want to be constantly swapping drives. I have a huge 486 full tower with room to...

    So here's what I did (using the 1.2MB drive in my DOS 6.22 system):
    FORMAT B: /F:360

    SYS B:

    This all seemed to work fine and I got my system files on the disk. Over on the 5150 it tries to...

    Yeah I guess that's the next thing I'll try is borrowing a drive from the 5150.

    Both drives have been removed, cleaned and lubricated. They were extremely clean already.

    I did find some DSDD disks.. I was able to successfully format the disk in the DOS machine. I tried both...

    I second robocopy, still use it daily for backups.

    Flags I use for syncing are: /E /R:2 /NFL /NDL

    Yeah I was actually pretty surprised by the condition, too - considering I pulled it out of a recycling bin. How did you get yours so clean?? Did you replace the front piece or somehow repair that...

    Thanks, that was it!! Working great now - probably doesn't come through in the pictures but the screen looks great. Never had one of these before, had no idea how long the ghosting effect lasts on...

    Yep after I flaked away the gunk, the wire is unattached, like the gunk ate away the exposed part of the wire. Will resolder and test tomorrow.

    Yeah I did this a few years ago in my house. Found 2 or 3 reversed. Found nearly my entire finished basement none of the ground lines were hooked up at all. Line just sitting there behind the outlet,...

    I traced the signal in from the A3 jack/pin through the TR18, into pin 9 on the SN7406, everything looked fine there. Coming out on pin 8, it hits a resistor, then a wire lead takes the signal to the...

    Interesting, what else is the alligator clip on the probe for then, if not for ground? The person who gave it to me (an EE) showed me how to use it and connected the clip to ground. As I'm sure you...

    Yeah I don't think I had a good connection on GND for reading the video card signals. BTW I am a bit of a scope newb - I know the basics but I may be doing something wrong.

    Here's what I have been...

    So I can't seem to get a good reading coming out of the video card either. Here's what pin 9 looks like. But the funny thing is, 6,7,8 & 9 all look exactly the same - this. Where should I be getting...
