There's a tape image here: https://www.stairwaytohell.com/electron ... page=other (turtle graphics), but it's rather a cut down version of Logo.

As you've got a compact, you've got sideways RAM so can load either logotron or acornsoft logo from a floppy into a sideways RAM bank. Do you have any method of making your own floppies? If so, I can make you an adfs image with both of those ROM files on it?

Do you mean; transferring stuff onto ADFS floppies?

I have about half a dozen 720K (DD) floppy discs here.

I am not sure whether my USB floppy drive will let me read them on either my Linux or my Macintosh box.

Most USB floppy drives will only work with "IBM" PC MSDOS formats :(

I've just come across two "things" called 'OmniDisk' and 'OmniFlop'; but, having been teaching until 9pm,
I'm "cooked" and will wait until lunchtime tomorrow to try and see where I can get with those, between
machines running Xubuntu 16.0402 32-bit and Xubuntu 14.04 64-bit and an ADFS formatted DD floppy,a USB floppy drive
and two sets of crossed fingers.

It won't work with a USB drive - you need a built in floppy controller unfortunately. :(

Or more correctly one that uses the same physical format as a PC type disk so :

single or double sided 80 track 9x 512byte sectors (double density format)
single or double sided 80 track 18x 512byte sectors (high density format)

So it would be OK for say FAT (dos,windows), or say ext2 (linux) formatted disks as they are phsically the same format, but logically different. For this reason I can write QL 720K disks on my USB floppy as they are double sided 9x 512byte, have to format them in windows as DOS first tho.

Though of course the practical upshot is that you can't write DFS or AFDS disks as they normally use 256 byte sectors, and in the case of DFS disks are more often than not single density disks to boot.

Cheers.

Phill.

Well, "luckily" I suffer from dirty habits and have a Pentium I that just copes with Win XP, and a Pentium III,
both with built-in floppy drives: but the first is currently running FreeDOS, and the second is running
Haiku OS, so will have to install ReactOS on the second as don't like
pirate software (as an idea), and don't have an XP licence.

So . . . . Saturday cometh . . .

You're all set - I'll knock you together a disc image today or tomorrow :D

If you're running windows, you need "omniflop" - I think under freedos you should be able to run omnidisk :D

Here you go - based on the ROMs on the bbc lives archive - there are two versions of logo-1. I'm not sure what's meant to go with what. I'm guessing 1&2 need to be put into sideways RAM?

Thank you very much indeed!

Why, on decompression does it result in a file "logo-adf" which is the Amiga Disk File Format?

That's the problem with 3 letter extensions, they can have more than one meaning! :D

Didn't really find much useful from a quick search, but there's e.g. http://acorn.revivalteam.de/?site=DiscImaging

Just to show that the "A" in ADF can mean other things.

Not my friend at all as I live in a Linux & Macintosh only world.

Anyway, using "Run Disk" in BeebEm 4a I get this:

Disc fault 18 at :0 00/00

which seems to put the kibosh on that.

It's an adfs disc in a format that can be written in omniflop for use on your master compact. As discussed earlier in the thread.

If you want to use it in beebem, try putting it into master compact mode first (if it has one?)

and if you want it on a dfs format disc image, just ask! I should add, there's nothing to run on there, it's rom images that you need to load in on a master with the *srload command.
