The cyclone V looks to be available, just a bit more expensive: https://www.digikey.ch/de/products/detail/intel/5CEBA4F23C8N/3879656 Also a case and mechanical keyboard were recently designed for the XE by @ScreamingAtTheRadio Not sure what the finish is like on the 3D printed version though? So seems much closer than for several years. I’m also going to mention @santosp here because he did the mini-itx and custom ‘mini’ pcb layout. Not to mention a lot more… For my part I’ve not touched the core in some time. I was merging in a video scalar I wrote and pokeymax into the core, then ran into some issues that seemed like work to solve.

Well I did contact them several months ago, offering this as an option. Though I didn't hear anything back after a few initial messages, so I think they prefer to build their own. Anyway I wish them best of luck with the project, whether they decide to build their own or use this as a basis.

Hi, I built an SIO2Midi S2 to test Pokeymax. Since I had to order a minimum of 5 boards I thought I may as well assemble them all! Note that they have both midi ports fitted but they do not have the optional Dreamblaster S2 fitted (you can order that here: https://www.serdashop.com/waveblaster). Looking for ~25CHF each + shipping costs as below Shipping to Switzerland: 2.65CHF Shipping to EU: 9CHF Shipping to US: 12CHF I have 4 available. Thanks, Mark

For the software try to consistently change kr1/kr2 within 30uS of the scan pins changing.

Sorry I did my best when I looked at this a few years ago. To make them work together well there are two options: Tighten timing in TKII firmware. Pokeymax hardware redesign to not use an i2c io expander.

Many thanks, its much easier to navigate with the table of contents!

Yeah I normally download it from the intel site. It does ring a bell that old versions needed to register for a free licence, but it's not been like that for years iirc.

Quartus lite is free to use, no need for a licence.

Pretty sure post divide is meant to be 2 on the channel 1 (Atari internal output) on the Pokeymax v3. IIRC I corrected that default on a second edition of core 1.23, perhaps this was flashed with the original one. Probably worth upgrading to 1.27. Also connect up the stereo output, its much better.

The dev guide obviously has a lot of details for the developers, but it does explain quite a lot: http://www.64kib.com/pokeymax_files/pokeymax_dev_126.pdf This diagram might help too, though it is somewhat out of date: pokeymax_block.pdf

It’s probably a new feature that wasn’t previously stored in the flash. When you update the core in pokeycfg it keeps your settings you see.

It seems that mechanical keyboards and keycaps are being made on other threads here now. Not cheap, but achievable. That just leaves 50000 USD + for the injection moulded case... We just need 10 people to put in 5K each, anyone in ??

Just wanted to pipe in to say, great project. Allows preserving the internals but adding dual pokey and memory. The keyboard click should be pretty easy to add, just need to snoop the gtia writes to the consol register too and mix that into the audio. Feature creep options: You could also add video too by integrating @ijor's recent work (https://forums.atariage.com/topic/350247-fx-antic-an-antic-chip-replacement-on-fpga/), though it'd need a larger device. Not to mention also adding turbo freezer and and ...

Is there something like 'companies house' in Poland. Does this company exist? The address seems to be for a technology park. I guess we know it is possible to do that. There are existing projects that bit bang the cartridge port using e.g. STM32F4: https://github.com/robinhedwards/UnoCart Also for example: https://cbm-pi1541.firebaseapp.com/ The pi zero has 40 gpio pins. It is possible to toggle these at 50MHz from kernel space. We need more io than this: address bus: 16, data bus: 8, joystick: 10 digital + 4 analog, r/w, phi2 -> already 40 and there are more than this needed for PBI. So it could be pi zero + a CPLD/small FPGA to do the exact timing and to increase the number of pins. I'd be happier for a pure FPGA solution personally, but a pi zero (or similar) solution would probably be cheaper and work well. The main difficulty would be modifying an emulator to get real cycle-cycle timing.

If it is no-one told me. Though the source and v1 schematic are open and on my site, so it’s possible. Looks like a cool project, I hope it is real! With an active pbi and cartridge socket it does seem likely to be fpga based rather than software emulation.
