MiST - FPGA ST
Hi,
see my little Atari-FPGA project here:
http://harbaum.org/till/mist
Currently TOS 1.00, TOS 1.04 and EmuTOS boot, TOS 2.06 throws an exception as there's no floppy implemented yet.
Video booting TOS: http://www.youtube.com/watch?v=OnB5dKg07OQ
Have fun!

Re: MiST - FPGA ST
Very nice! Will you be producing any runs of this or are you relying on someone (perhaps Lotherek) picking it up?

Re: MiST - FPGA ST
I have built a total of eight boards by now. I am looking what the options are and i have contacted Lotharek some weeks ago.Dal wrote:Very nice! Will you be producing any runs of this or are you relying on someone (perhaps Lotherek) picking it up?
However, i have five spare empty PCBs i'd be willing to share immediately.

Re: MiST - FPGA ST
WOW! you made whole project in just four months? 
is it 100% compatibility with original ST? (all games works?)
btw why Suska board is so expensive...?

Re: MiST - FPGA ST
Nice work. Looks good.
It looks like a hardware project (PCB only)?
By that I mean did you didn't develop your own Atari ST core? You used the open-source one called Suska core developed by Wolfgang?
Still very cool work. A lot of NRE and it is no mean feat to create a BSP (board support package) to map/convert a core like Suska's I/O to the capabilities of your PCB. Porting cores to the MiniMig v1.1 PCB (excluding file I/O) could take days of playing around to shoe-horn it in.
The media interfaces were always the hardest. Fortunately a lot of smart guys have done a lot of work in this area and opened up their source. (Yaqube especially)
So have you managed to get the Spectrum, MSX, Megadrive and Atari cores on your board?

Re: MiST - FPGA ST
it's not Wolfgangs core. It's a new one (much simpler than Wolfgangs) which i wrote from scratch based upon parts i took from the Minimig.alexh wrote: It looks like a hardware project (PCB only)?

In the meantime a bunch of games are running. Examples:

Re: MiST - FPGA ST
Interesting and impressive.In the meantime a bunch of games are running. Examples:
The Oxyd game is nice. Xenon 2 has sluggish sample playback and very fast chip music. Out of interest, for Frontier, how fast is the emulated 68000 running, as the frame rate seems to be reasonable for that game

Re: MiST - FPGA ST
In one of MasterOfGizmo's earlier Youtube videos he mentioned in the description "The current core is clocked at 8MHz like a real ST and runs ca 15% faster than a real one. TOS 2.06 supports up to 14MB of ST RAM." You can have a look at the video here: http://www.youtube.com/watch?v=uTA8JP6hJ-U (running GemBench for example)
Re: MiST - FPGA ST
Wonder if it can go faster... like having a switchable super-turbo mode for apps.

Re: MiST - FPGA ST
The Amiga/Minimig folks have accelerated the very same setup to ca twice the speed of an Amiga 3000. So yes, there's much room for improvement. But for now i'd like to stay as st compatible as possible. The CPU is explicitely slowed down to the speed of an 8mhz st.wongck wrote:Wonder if it can go faster... like having a switchable super-turbo mode for apps.
The color video mode currently runs at 72hz. This may very well affect the xenon audio output.
This is an early version. Things will sure improve ....
Edit: The Atari core now supports 50Hz and 60Hz video modes as well as a 56Hz mode for those VGA displays that don't support 50Hz. Many games incl. Xenon II now play their tunes at the correct speed.

Are you working on this prjoect with Lotharek? I've seen the "MIST" listed on his site
Is there a date planned to sell this nice piece of hardware?

Re: MiST - FPGA ST
Hey MasterOfGizmo, this may be slightly off topic, but if you're able to do this (MiST), is it possible you might bring a TT030 or Falcon clone to the table some day? They're so expensive - if you can even find one for sale... I don't know if I'd ever be able to experience those environments otherwise. MiTT? MiF? 

Re: MiST - FPGA ST
Before mass production i will like dvi or hdmi, probably thats best way.
If you guys expirience hardware problems.
1. Always remove chips if possible before soldering.
2. Resolder your hardware, check cables too.
3. If problem continue THEN must be faulty software.
I got 2 Atari ST
Main is stfm, with blitter, with 4 meg of ram, with 16mhz cpu + s-video and audio input to videobox, vdi out
P.S.
My english may not be correct

Re: MiST - FPGA ST
Hopefully the first MIST will not be the last one. So instead of adding new features etc i prefer to get this one our of the door asap. But hdmi definitely is an option.Nikolas wrote:Before mass production i will like dvi or hdmi, probably thats best way.
The Minimig really brought new life to the Amiga scene. Maybe the MIST will be cheap enough to do the same for the Atari ST. And of course the MIST is also Amiga compatible, so you get two machines in one.
The thing i currently enjoy most is its size. You can put it in your pocket together with its tiny power supply, take it with you to a friend and play Oxyd.

Two? MIST will undoutably take all the open source FPGA re-creations of classic computers.MasterOfGizmo wrote:And of course the MIST is also Amiga compatible, so you get two machines in one.
C64, Amstrad, Sinclair Spectrum, Megadrive, NES, Colecovision, Vic20, Astrocade, countless FPGA Arcade games.
The hard work will be in making a clean BSP (board support package) so that core developers can port their core to the board and be able to use all the I/O easily including the SD card. (Which is where MiniMig v1.1 falls over because the ARM/PIC firmware wasn't in a great shape).
I look forward to it.
