Re: EMUTos + AltRAM

That was a physical hardware limitation of the 68000 chip. I don't think emulated 68000 need to have that limitation. There are cases where that emulation is needed (Hatari for example has an option for it). For example, in TOS 1.04, the vector number is placed in the upper 8 bits for exceptions. A...

Re: PAK/3 TOS 3.06: UK Version?

Now all I need to do if find how to recalculate the CRC. If you use the script i posted on atari-forum, tospatch will set the CRC for you. If you don't want to patch anything and just fix the crc, you can still use that script and just remove the line that includes "_us2uk.fil". If all el...

Re: Using Pure C from floppy

Is there any way to strip the distrubution down to a size where it will fit on a 720K floppy but still actually be usable? That might be possible, but it won't leave much room for your own files. All you need is PC.PRG, the LIB directory, and the include directory. You can omit all those *.hlp file...

Re: NetBSD 7.1 on the Atari TT

Since this is currently also discussed on atari-forum: @Icky: do you have a way to verify that newer versions (currently 9.2, but also everything >= 8.0) work on real hardware? We have problems getting them work in Hatari and Aranym (for Aranym, only the FALCON kernel, since it only emulates a 040)....

Re: PiStorm Chat

Anyone who can proffer something on the Musashi code for handling bus errors please tap me up as this is the biggest hurdle to progress ATM. Its been quite some time i worked on this, but AtariX (the MagicMacX successor) also uses Mushashi. Checking for bus-errors is done there m68k_read_memory_* f...

Re: FPU Emulator

Apparently TOS 1.xx is using LineF for non-fpu stuff.. so for now, it wont work on that old TOS. Yes, that's true, up to 1.04, AES & desktop abuse the LineF handler to shorten some function calls. But that's no big deal, TOS <= 1.04 doesn't support 68020+ anyway,. I wouldn't really expect anyon...

Re: Basilisk II Atari

Quite impressive if i think about it again ;) Saw also some pictures from Frank.lukas.

Do you direct MacOS graphic calls to the VDI, or how do you support graphics cards? I doubt that macOS does know anything about ET4000 in Atari ;)

Re: MMU operation and ST Startup & running where does code live?

Does the MMU remap any physical block(s) into anywhere in the CPUs address space? How do I set mapping and set protection on regions of memory? Question about ROM have already been answered above i think. Regarding MMU: as normally only TT and Falcon can have one, TOS 1.x and 2.x don't do anything ...

Re: Availability of TOS ROM source code

TOS 2&3 are available here: http://tho-otto.de/downloads/tos306de.tar.bz2 Don't get confused about the archive name, both TOS 2 & 3 can be built from it, as well as all language versions. Hope to get that also in git soon, just wanted to clean it up a bit now that TOS 1.x is in a separate re...
