I am looking for a CP/M boot disk for the Disc Controller
Hey all, I'm new here.
I just fixed a Model AD, a memory expansion and a disc controller expansion.
I don't own a real diskdrive for this device, but it seems to work with a FlashFloppy Gotek.
It looks like I need some kind of CP/M boot disk to boot to CP/M.
Does anyone have a Gotek compatible disk image for me?
Thanks!
Kind regards,
Kris (from Belgium)

Re: I am looking for a CP/M boot disk for the Disc Controller
I've been trying to create disk images myself using the HxC IPFConverter tool.
They were based on the disk images I found in the files section of this website (emulator, 22disk and the cpm bootdisk downloads).
However, I always get the same result.
The Gotek lights up (so there is action), but after a few seconds the computer responds with "No response from the disc controller".
Could this mean there is still a problem with the hardware setup?
Or can this still be invalid disk images?
Thanks guys!

Re: I am looking for a CP/M boot disk for the Disc Controller
In the `discs` subdirectory of the emulator you will find a file named `system.dsk`.
That file contains the first sectors of a newbrain Double sided floppy disk. These sectors contain the CP/M system and if you can write them to a floppy disk you will be able to boot. The other disks you mention are only the files contained on them without the System sectors which are not files you can copy as usual.

Awesome, thanks, I will try to create one with that.
Which floppies did NewBrain use? 3.5" or 5.25" and what size?
Thanks.

Sadly that System.dsk file from the emulator doesn't work on the gotek.
Also converting the file to another format using the HxC IPFConverter tool is not helping.
Too bad :'(

Re: I am looking for a CP/M boot disk for the Disc Controller
Load a disk on Newbrain emulator with CP/M support.
This will create a .dsk file on the `discs` subdirectory.
Do NOT close the emulator. Go to the `discs` subdirectory and copy that file and rename as `<filename>.raw`.Then close the emulator.
Try to work with this .raw file.
