PiStorm Chat

[Steve]

With the thanks to @dad664npc this weekend I've managed to get my H5 up and running with a Pi4 & Pistorm. Firstly I had to swap out the 4x 373 latches on my Pistorm with 374 latches (Thanks to Lemaru on the Pistorm discord for sending them to me for free!) Then I drove to Cambridge to the official Pi-Store to buy myself a Pi4!

I just had to share the results - OH MY GAWWWSH! Especially in the H5 it fits absolutely perfectly, I can even close the case and install the keyboard! there's plenty of space between the Pistorm and Pi4 using a GPIO extender, I installed a fan and a heatsink on the Pi4 to be sure.

@Badwolf Really hope you manage to come back to the project sometime, we'd really like to see extended VDI display resolutions from your original project ported over!

Anyway, check out these pictures!!!

We need more people to come and try it out, come and give it a go!

Good work - Finally someone else to feel the performance of the PiStorm on an Atari ST. Loving the H5
- you've got me interested

nice figures

That looks great @Steve, I’ll have to get the bits together sometime and give it a go.

What are the speeds like without NVDI ?

Very nice.

BTW First picture comparison is against Falcon (the 60% RAM speed worried me at first!), but the absolute figures are still valid.

Oh yeah that makes sense now, I wondered why the integer division was lower than mine PiStorm is (in my opinion) going to become the perfect upgrade for a H5. @Badwolf we have PeP (a very good Atari driver programmer) in the Discord at the moment to advise on driver development. I hope you get some time to lend your advice to get the HDMI display output going

FYI a device has been made which can connect to 15KHz 5v RGBHV digital I/O and convert to MIPI camera data to send to a PiStorm to display native video over HDMI. This allows native video and gfx card video over a single HDMI. The project is currently in a private repo but I am told that it might be available "soon". You may have seen Claude demonstrating it in his twitter feed using a vast array of ultra-low cost FPGA devkits (including Sipeed Tang Nano 9K).
