I see min size 17x17mm and also 26USD (edit: 6USD on aliexpress), but perhaps I'm missing something? Is it 5v tolerant so the level shifters can be removed? The MAX V is not 5V tolerant and doesn't have a PLL. I don't recommend buying these chips at Aliexpress, 2 Quote Link to comment Share on other sites More sharing options...

Yes, it is Linux, I will look it up. In the meantime - will one of those cheap USB Blaster knock-offs be sufficient? Because I can't really justify spending money on the genuine thing...

ScreamingAtTheRadio Posted April 17 Share Posted April 17 Hello everyone. As promised, here's a git repo with @foft's PokeyMax 4 imported in KiCad: https://github.com/bleroy/pokeymax I'll also post this on the other thread that I just learned about: I also pushed the gerbers and bom to JLCPCB to get an idea, and quite a few parts are still missing, including the fpga. I'll make an attempt with PCBWay to see if their inventory does better... 4 1 Quote Link to comment Share on other sites More sharing options...
foft Posted April 19 Share Posted April 19 The parts get quite a lot cheaper in volume at DigiKey so if anyone is able to make 50+ and ship them that’d be best! I don’t want to get into shipping more than 5-10 I’m afraid. I was wondering about the Abbic shop… Did you import the version with larger drill that allows for super cheap pcbs? Actually that is only a problem with low quantity, at 100+ small drills are ok. Quote Link to comment Share on other sites More sharing options...
olix Posted April 19 Share Posted April 19 Maybe Duddie can take over production, sales and shipping again? 1 Quote Link to comment Share on other sites More sharing options...
madness77 Posted April 28 Share Posted April 28 I believe that since SID has been implemented in ARM microcontrollers (ArmSid) and even in Atmega (SwinSid), it would be all the more feasible to emulate Pokey on ARM, which could bring the price down below $30.

woj Posted May 7 Share Posted May 7 On 3/26/2024 at 7:42 PM, foft said: Happy to help. Should we make a new thread for this though? I checked a real pokey too. The mister one was forked off slightly older code and ported by Alexey. There are clearly some drive emulator changes to plug it into the mister framework (maybe compare vs http://www.64kib.com/atarixlfpga_svn/trunk/atari_800xl/firmware_eclairexl/atari_drive_emulator.c) I've not reviewed exactly what he did. Coming back to this, waiting for the PCBs to arrive (it seems the PokeyMax 4 one will not come in time to assemble it next weekend :/) and now having a working Quartus installation I made sure I can compile the MiSTer core from sources (not fully done, the ARM C code is still the precompiled bin files and it might be I need older Quartus recommended by the MiSTer community) for any future experimentation. However, I also looked at diff of the basic VHDL files for Atari chips in the MiSTer core and yours that you made available and the changes are far from trivial. Trying to sync this by hand knowing little about FPGA practicalities is most probably not going to work for me. So now I wonder how to approach this practically, it's such a waste that the MiSTer core is lagging behind and still having so many bugs... Perhaps a new fork altogether, I don't know...

foft Posted May 7 Share Posted May 7 (edited) Probably easiest to: i) Find the svn revision that was original ported (starting by date of the original port) ii) Find the diff applied to port it to mister. iii) Take HEAD of http://www.64kib.com/atarixlfpga_svn/branches/trunkv37/atari_800xl/ from svn (trunk is a bit ahead of the eclaireXL releases at the moment) iv) Apply the mister port diff. Though honestly I'm surprised I changed that much. I should probably try to build the MiSTer core at some point...

foft Posted May 7 Share Posted May 7 I put a few of the fixes that seem significant here: https://github.com/scrameta/Atari800_MiSTer If this works better for you I can raise a PR. 2 Quote Link to comment Share on other sites More sharing options...

Finally got to this one too Well, first there is a warning complaint that the t65 stuff is missing, it does not seem to matter, at least not till the point I got to, just saying. Nevertheless, the compilation fails, see the picture. I have Quartus 23, and I did have to make soft link from pll_q17.qip to pll_q23.qip on the original Atari800_MiSTer repo project to make the compilation work, here I also did this, but I do not think this has anything to do with the quoted error, the error looks like a "solid mistake" Quote Link to comment Share on other sites More sharing options...

And, Joyride finally works / loads, the screen you see is something I was not able to get to before! So it is an improvement. Some things are still as they were - Rewind demo does not load (crashes very interestingly during loading), Alley Dog loads and runs for a large part, but then the graphics crashes (this was so in the main version too). I also understand from other posts that the status for both Alley Dog and Rewind is the same on EclaireXL, so this is not a question of porting the Eclaire XL changes to MiSTer, but more generally of the compatibility of the FPGA development. As there were also numerous reports of the new Mikie game not working on this and that (including the stock hardware), I also tried that (version 1.09) and this one failed during loading in the most interesting way, it essentially made the MiSTer Atari core do a thing that Atari cannot do it seems, I will let people in the game thread know too. It is interesting to see that this game bends the hardware so much...? But, the main point for me is essentially this - how to effortlessly keep your developments for the Eclaire XL and anything else you are working on in sync with the MiSTer repo... I would like to offer something of the kind "I will keep an eye on your repo and implement the corresponding changes in the MiSTer repo" but I know I will eventually loose it and will have a problem keeping up this promise. EDIT: I also ran the ACID tests, the Pokey IRQ timing tests now pass, there are only two failed tests left, see photos, and it might be that the serial timing one is due to disk emulation perhaps? The Antic DLI timing bug does sound like something that can mess up these demos and games though... Edited May 12 by woj Quote Link to comment Share on other sites More sharing options...
foft Posted May 12 Share Posted May 12 Hmm, will look what is up with those. Should all pass. Which acid version? Quote Link to comment Share on other sites More sharing options...

With the things I was testing the new commit behaves the same as the last one (for which reason I will probably have to recheck if I compiled the new code, but I did pull the stuff and I have seen the report on the changed files...).

foft Posted May 12 Share Posted May 12 (edited) Oh too bad. Guess I should download quartus 17 again and connect the mister up/see what is up. I’ve not used it for a bit since messing with the hybrid Amiga core a year or so ago. Edited May 12 by foft 1 Quote Link to comment Share on other sites More sharing options...
