Nearly there some help please!
« on: February 06, 2007, 12:48:57 PM »
Hi,

I'm trying to get adf images from pc to an amiga floppy. SO far have formatted a 720K on the PC, and used crossdos to see the file on the amiga side.

I think i now need to:

1. pack an 880k adf file so it fits onto 720k floppy
2. unpack on amiga side
3. write to an amiga disk.

I'm not sure where to get the software to pack a file to LHA on the PC side.

How to unpack on amiga side.

and how to write to amiga disk,

can anyone help and give me some links to where I can get the software.

(amiga 1200, no HO, 2 floppy drives)

Thanks, Rick.

On your Amiga, mount PC0 (on the Storage or Extras disk I think, inside DOSDrivers). Then put in an 880k disk and format PC0. Then put the disk in your PC and it will be accessible.

Download lha.run from Aminet. Copy it to the disk along with your compressed ADF image. Put the disk in your Amiga. Copy lha.run to RAM: and run it. The copy the resulting lha file to C: on your Workbench disk. Then use lha to decompress the archived ADF, then use trandisk (also on Aminet) to write the ADF to another floppy disk.

@rja4096: Hello and welcome to A.Org!

You're almost there...

You'll need:
7zip or something similar on the PC to compress the ADF into a ZIP file (don't worry about a PC version of LHA), or you could even use the ZIP functionality built into Windows XP
UnZip for the Amiga
lha  self-extractor so that you can extract the UnZip archive
ADF2disk so that you can write the ADF back to floppy

I have to disappear now for a while, will post the rest later if nobody's responded!  :-)

In a nutshell: you'll need to run the LHA file, which will give you an executable of LHA... Then use that to uncompress UnZip and ADF2Disk (all to the RAM disk).

As you have no hard drive  :-o  you'll have to run most of this from RAM: or alternatively, butcher a backup of your Workbench disk to make enough space for at least UnZip and ADF2Disk.

Finally, you'll need to compress the ADF on the PC, copy that to 720Kb disk, then on the Amiga, extract that file directly from the PC disk to RAM:, and finally write out the ADF from RAM: to a fresh blank disk.

I might consider putting a quick tutorial together for this, with screenshots, if it's of use!
