Bit3 80 Column Mode with ATR8000 [message #170002] |

I recently acquired an ATR8000 and was able to get it hooked up to my Atari 800 and use it both as an Atari drive controller and to boot into CP/M.
My 800 has a Bit3 80 column card in it, and I understand that the ATR8000 CP/M terminal emulator can support this, but I have no documentation of how to enable 80 column mode when going into CP/M.
Does anyone here have some information of how to do this that they could share with me?
Thanks.

I cannot help with the Bit3 card, but I do have to ask if you have a means for
duplicating the ATR8000 system diskettes. I have an ATR8000 that came to me
without software and have been unable to find the system software.
I inquired about this on one of the Atari forums, but never saw a response.

I can certainly duplicate the Atari format disks that came with it and send you disk images. The CP/M disks may be more complex, but I will attempt that as well once get the drive cleaned and tuned up.

Thanks! I believe there is an issue where the first track (or is just the
first sector?) has a different sector size and this complicates re-generating
a working master from an ATR. I will try it out and see.

I understand that the CP/M ones are problematic for the reason you mention. Normally one could use an app link TeleDisk or ImageDisk on a DOS PC with a 360K floppy to make images and recreate disks, but the boot track format makes this difficult with the ATR8000 CP/M disks. I'm going to try to just create some new bootable physical disks, and then see if anything can be done to create a usable disk image. I have copies of CP/M, MS Basic, and Wordstar for the ATR8000, so I'm very interested to see if this works to be able to preserve them.

There's a discussion here about imaging the Indus CP/M diskettes. I suspect
the ATR8000 format may have the same issue:

Hit send too quickly on the last response... The CP/M images are the ones
I've been in need of. Dunfield's ImageDisk should be able to handle the mixed
sector sizing, although it may take a control file or set of option flags to
pull this off.
Contact me privately if you do extract any images and need them tested on
other machines. There have been a number of requests on the various Atari
forums for workable ATR images and the community could really benefit from
their availability.
