svhovater Posted August 30, 2020 Share Posted August 30, 2020 hi all A bit of a journey here.. dusted off the old ATR8000. I have quite a few CP/M (ATR8000) disks that I'd like to recover, but.. but I can't seem to boot the ATR, and read the disks. So... I got a GreaseWeazel (blue pill) thinking - read the disks, convert the scp to something that I could load onto FlashFloppy, and move forward. Well, the GreaseWeazel is assembled, FlashFloppy installed (on Gotek) acquired. Now, reading the disks. It's comforting to hear/see the drive step through the tracks, and an scp file *does* get created. However... the HxC software track analysis (using MFM and/or FM) says the disk is blank. While it's possible that the disks got erased in the last 32 years, I guess I have a hard time believing that, given that other (Atari) disks were stored in proximity and read ok in Atari 1050. So.. anyone else playing in these spots? Advice? (besides the obvious "hey NOOB" ) Steve Quote Link to comment Share on other sites More sharing options...
svhovater Posted August 30, 2020 Author Share Posted August 30, 2020 update. appears I have bad drives. Swapped out with a different drive, and I'm getting data. Which is encouraging. Side 0 seems to be problematic, side 1 seems to read better. So, another bad drive, but one side is working.. Guess we're off to Ebay to find a known good drive.

svhovater Posted September 14, 2020 Author Share Posted September 14, 2020 well.. the new drive didn't fix it. So I followed advice from this forum, and ordered a replacement 1797. The replacement 1797 from Ebay arrived 5 minutes ago. It's in, and ... and... I have an operational ATR8000! 3 Quote Link to comment Share on other sites More sharing options...
svhovater Posted September 17, 2020 Author Share Posted September 17, 2020 So, the new quad-density drive (720k 5.25inch) is connected and the new 1797 is in. I'm able to boot a quad-density CP/M boot disk. (yay!) I've connected a flashfloppy-enabled GoTek, and now we're off to the next hurdle. I'd like to use the gotek as a second drive. In fact, I can define an image (we'll get to that) and have it appear as drive B. That's great! I can format drive B with DDINIT, however, I'm unable to ddsysgen it and unable to copy files to the formatted disk. I don't know how else to get an image for the init, so I just copied a text file and renamed it appropriately. I just thought, "it's bits that will get overwritten during the format", but I have my doubts as to whether this approach will work. Anyone having success with flashfloppy/gotek & ATR8000 cp/m ? thanks! 3 Quote Link to comment Share on other sites More sharing options...
svhovater Posted September 19, 2020 Author Share Posted September 19, 2020 Well .. good tip from Kier, of FlashFloppy fame.. Using a blank HFE file instead of an IMG allows me to format the HFE file without having to take into consideration the weirdness of the ATR8000 CP/M disk geometry. I formatted (ddinit) the blank HFE image and wrote system tracks (ddsysgen) to it. And now I've booted from it! I'll gather up files and post in the morning. All you should need to get CP/M going on your ATR is the gotek+FF, and the coming HFE file. 3 Quote Link to comment Share on other sites More sharing options...
+kheller2 Posted September 20, 2020 Share Posted September 20, 2020 I want an ATR8000 now. Quote Link to comment Share on other sites More sharing options...
svhovater Posted September 20, 2020 Author Share Posted September 20, 2020 Here's an HFE - it doesn't contain the full CP/M distribution, but basic files like DDSYSGEN, DDINIT, etc. I'd like to hear if you get this working on your end.

moonlight_mile Posted September 21, 2020 Share Posted September 21, 2020 This sounds very very interesting. I have an old hxc2000 that I use for my Atari st. Is it possible to repurpose this as an ATR drive without loosing my Atari St functionality?Below is a pic of one similar to the one I have.

svhovater Posted September 23, 2020 Author Share Posted September 23, 2020 So, I don't know the interface for the hxc2000, but I suspect that it knows how to do hfe files. Question is how you'd connect it to your floppy drive port. Card-edge connector? Bottom line, it sounds do-able. Quote Link to comment Share on other sites More sharing options...
moonlight_mile Posted September 23, 2020 Share Posted September 23, 2020 Yes it is HFE compat. It connects to the ST with the 34 pin floppy connector. I tried plugging it into the ATR the other day but I got no activity beyond getting power. Though I may have had the jumpers in the wrong places. I am gonna give it another try today or tomorrow. I attached the jumper settings for the st and pc from the manual. I am thinking I probably should use the pc settings. What do you think?
