Awesome thanks, something to fiddle with :cheers:


Let me know how you get on with it:)

Hi all,

The 030 boards i designed have arrived. I'll try it in the Atari STFM i have later this weekend...

TOS 2.06 _or_ KAOS 1.4 is needed for CPUs >= 68020. The advantage of KAOS would be that it fits in unmodified 520/1040STF machines, as it is the same size than TOS 1.04 (192 KB).

EmuTOS is even better bet. There are 192k, 256k & 512k versions, ROM, floppy & program versions of TOS, debug symbols, sources, it supports every possible Atari model and additionally ColdFire Firebee & evaluation boards, even Amiga,,,

Would a system with a 68030 be able to boot EmuTOS from floppy with the original Boot roms?

I don't know... There would need to be something in ROM that would load & execute floppy boot sector, and is compatible enough with 030 to do that. Easiest is just to test it, new EmuTOS snapshot was just released:

A original Atari ST TOS 1.0/1.02 or 1.04 will not work with a 010, 020 or 030 CPU, you must install 6x 27C256 Eproms with EmuTOS in the ST machine ...

I think I might have confused you guys. I'm talking about the original Boot ROM... from 1985. Not a specific TOS. The roms would load any TOS from disk. I guess this could be tested in an emulator?

In this thread is the boot ROM: viewtopic.php?t=19320

Also found this: Multi TOS booter for 260ST. http://atari.8bitchip.info/tosload.htm

So I was thinking you stick this ROM in a emulator, change the CPU to 68030 and boot TOS 2.06 from virtual floppy? Don't have a emulator setup to test this conveniently. Far fetched?

I have a T_Board that fits in the 68K socket and gives the original ST a 2.06 ROM.

I couldn't get it to boot :( I've not spent any amount of time on it yet though. I was sent some updated firmware, but haven't got around to installing the xlinix tools and working out how to flash it yet. I think TF said there was a more lightweight flash program because I haven't enough space to install the full xlinix software package on my SSD. I'm fighting the E-clock on the STFM at the moment so can't concentrate on another project right now :(

Last "app" of this link: http://ataristeven.exxoshost.co.uk/Steem_apps.htm, should work on hatari, don't know, but you can give it a try.

I gave this a try. The boot TOS works fine in both Steem and Hatari. Hatari detects the Boot TOS as v0.00. Changing the CPU setting gives and error saying the TOS version must be >1.4. This is of course true, but is it a Hatari programming feature or an actual fail?

Maybe boot TOS just doesn't include correct TOS version number?

(Hatari needs to identify specific TOS versions so that it can patch them when necessary.)

Yep. That's stopping me from using it at the moment. No VDI blitter acceleration.

same here, what's the point in adding support for so much third party hardware if the genuine atari hardware isn't yet fully supported.

Bear in mind that EmuTOS is developed by very few people free of charge and in their spare time, so things get added a) because someone contributes them or b) because one of the core developers has time and interest in adding them. I'm sure if someone contributed Blitter support it would be included in EmuTOS.

Any volunteers in this forum?

Hi,

at first the Blitter isn't needed anymore with a 030 CPU because the Blitter would stop the CPU and the CPU is faster then the Blitter with 8Mhz. Next, TOS2.06 should also boot with 030 CPU but does not Supports TT-RAM (pak68/3 was also running with TOS2.06). Maybe what should work is the PAK Tos, PAK tos is special patched to run with 68030 cpu and TT-Ram. There are also the Patches available for it.

Well, yeah but it's true only if you have a 68030, my concern is about the guys who don't have one (like me for the time being), i remind you that it's possible to use emutos on real atari st(m)/f(m)/e hardware in replacement from the tos, and it's true that emutos is overall a good replacement, except in this one usage. I was just answering to the previous post (which i quoted), saying it support every possible hardware INCLUDING stock sts. In case of a stf(m) where the blitter has been installed by the user (or a st, since it was possible to find a board adding the blitter in motherboards prior to the c070789) don't you think that it would be a waste to not use what you have paid for? In those st, a part of the hardware is NOT supported. It's also true for the ste, and i have both a stf with c070789 motherboard and a ste, both stil having a 68000.
It's off topic, i know, but i just answered to a particular post that i quoted (and to a particular point of this post), not to the whole thread.

BTW the only thing i implied in my previous post was just that it was bothering me, not that it was a bad replacement. Without this small issue, i would have installed emutos in my ste since months allready.

Yes you are right, maybe you could send a message to the EmuTOS Mailinglist with a request to add it into the source. Later I will try to run EmuTOS on my PAK68/3 and will test it.

Done since months, via the facebook group.
