Hi everyone,

I'm new to the forum. I'm retrogamer and I'm getting back into DOS gaming. Inspired after seeing Silpheed, I'm planning to acquire a Roland MT-32 so I can play it properly.. 😀

I have a problem, though, and I am hoping someone can help.

Most of my old 3.5 DD floppies (loaded with DOS games, which I have held onto for all these decades) were formatted with a program called 800.COM. I think it was a TSR.. It allowed formatting floppies to 800k instead of 720k, which was great! Except now that I don't have 800.COM anymore, I can't read any of these old floppies!

Is anyone familiar with 800.COM and/or do you know where I can get it? Hours of searching on Google has yielded nothing helpful at all.

Thanks in advance..

Check out my high scores and accomplishments.

This may be close enough, if not the exact thing you're looking for. It's not very intuitive, but you run the formatting program with a "TSR" parameter to install support for overformats in DOS.

HCFloppy's documentation suggests that 720KB disks formatted to 800KB should be readable in DOS without a TSR, since that format doesn't do anything super fancy (it adds a couple of sectors per track, something that DOS should handle just fine).

If your disks do have that same format, hopefully they aren't FUBAR in some other way.
