hi @agranlund any chance of sharing your 64mb restricted version of maprom? I've just got my mega working with the TF536 but sounds like its got the same issues you have with the firmware.
If it ain't broke, test it to Destruction.

I was convinced the version on Github had that but it appears not. I'll push the new ones to Github, just need to recompile and give them a test first :)


If you want to, you could try this EmuTOS build just to see if it starts (it stops looking for TT-RAM at 64MB)
http://www.happydaze.se/wp-content/uplo ... k.img_.zip

Disclaimer! This is what I run on my machine and it's built in a way that suits my setup. I really don't recommend anyone else using this one over the official builds.

(It has these changes)
* Stops looking for TT-RAM after 64MB
* It's built with -DSTATIC_ALT_RAM_ADDRESS=0x01000000
* It's built with -m68030 so wont work on a 68000
* Blitter is being detected even on machines with 68030 and/or alt-ram
* The "Change resolution" option brings up the resolution picker dialog and it's possible to freely switch between Low/Medium/High. At boot it switches to the resolution in emudesk.inf regardless if it's low/med/high and status of mono detect signal.
(This probably works on normal UBE switches but I can't say for sure.. My UBE switch is modified to react and toggle the mono detect signal before TOS has a chance to freak out in the VBL handler)

Thanks @agranlund ill give that version of TOS a test after I've wiped a couple of eprom.

In other news, removing the resistor networks and fitting the ide buffers works great on my Mega ST.

Can someone test the 1-19 freemint package with the TF536 and EmuTOS or TOS 2.06 ?

Snapshot -> https://github.com/freemint/freemint.github.io

... is the Fastram working and make MiNT use of the PMMU from the 030 CPU ?

@PhilC, you can grab the new version of maprom.prg/fastram.prg here:

Started from EmuTOS and using NVDI 5.03:

Appears to be using fastram but not MMU. I never used Freemint before so I really have no idea if you can enable the MMU and memory protection by editing that config file or not? I downloaded the ST/STE snapshot.


Slightly off topic, but now that I have Freemint installed... do you know if it's possible to edit or change the font used for the menu bar and window controls in whatever it is that controls this in Freemint (xaaes? teradesk?)
I really can't stand those almost comically oversized controls in mono mode.. the Atari desktop looks equally hilarious by default of course but VDIFONT is able to make them into a more normal size.

This is not a good use of pixels :)

I doubt whether it's changed, but you used to have to use a different MiNT kernel for MMU. That'll be the memory protection 68030 kernel.
Intro retro computers since before they were retro...
ZX81->Spectrum->Memotech MTX->Sinclair QL->520STM->BBC Micro->TT030->PCs & Sun Workstations.
Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

That was it :) That 030 specific kernel makes MMU memory protection work.
Also, it launches fine from TOS2.06 as well. Just stick fastram.prg in the auto folder, before mint.
