View Full Version : CP/M Single Density Disks via a Commodore 1571?

October 26th, 2016, 09:12 AM
I finally got my OSBORNE 1 (single density) running, but have no software for it. If I were able to use the 1571 I have (I can construct the cable to connect it to a parallel port) would I be able to write disks in single density format? I find conflicting specifications online on if I can do this or not.

It IS possible. There is a program that used various CP/M formats. I've forgotten the name.

I don't believe that FM is possible. Double-density (MFM) formats, sure, but single-density (FM), not as far as I can determine. See the 1751 User's Guide (https://ia800700.us.archive.org/28/items/1571UsersGuide/1571_Users_Guide.pdf).

There are a lot of people here that can create a disk for you. PM me if you want 1 or 2 boot disks. A comm program can fit on a boot disk and then with a serial cable you can transfer programs to your Osborne. I seem to recall you don't even need a null modem adapter with the Osborne. I could be wrong. A user in Brazil recently got started this way.

Your disks are on the way. You can make a donation to your local non-kill humane society. Let me know how it goes.

Got the discs, and everything seems to work fine. I'm not sure how to use the modem program you sent though, all the guides I can find are for Kermit. I made a donation the Yavapai County Humane Society, thanks for you help!

I think it will do xmodem but it's been awhile. Kermit is great though and I think that progra
Supports it.
