Success with disk 1! I had to use the image called M512_X_IMG and write it as 640k -format!

Well I've tried all kinds with the rest and zero luck. Did you get round to fixing the start from sector 01 issue jgharston? :)

Hi All

I'm struggling to get these files onto a suitably formatted disk ( 3.5" 800k created in OMNIFLOP ).
The disk images are fine 'its the software in folders' I need help with.

I guess what I need to know is how to add files to a formatted 800k DOS+ disk.

Update

Nailed it... using Virtual Floppy drive to create the image ( suggested by Jon Welch ).
Then dumping the image onto a 3.5" using ADFS Master 512 DOS 720k Format in OMNIFLOP.
All done on my trusty OMNIFLOP XP PC.

Good work - it's a classic chicken and egg this one. I've almost reached the stage of using punched tape...

Has anyone got this working from data centre with the raspberry pi 80286 processor emulator for the master 512?

I think it needs dosplus version 2.1 because I've got 1.2 on 5.25" disk but this errors with unable to load command.com.
(I don't have any facility to build new 5.25" disks from PC)
If anyone has got a working disk image for data centre which I can CFRESTORE to my sd card then I will be your new best friend.

Andrew :D
