hxlnt Posted August 20 Share Posted August 20 Amazing project! Looking forward to grabbing one of these for some 6502 homebrew experiments. Hope they don't sell out too fast. 🤞 2 Quote Link to comment Share on other sites More sharing options...

You might have seen I'm now using one on my homebrew 6502 build. https://github.com/visrealm/hbc-56 It's very convenient, not having to deal with the VRAM, clock and composite output components. 2 Quote Link to comment Share on other sites More sharing options...
visrealm Posted August 21 Author Share Posted August 21 My Tindie page is live now and I've just made some initial stock available to purchase. Note: I'm going away for a week from this weekend (back on September 1st), so I've only made available the quantity I'm confident I can ship before this weekend while also being able to ship stock to @arcadeshopper. There's a chance I'll put more up later in the week. US/Canada: For now, I've disabled shipping to US/Canada to give a chance for Arcade Shopper's stock to arrive.

Duewester Posted August 21 Share Posted August 21 Hey this is great progress. @arcadeshopper, could you please put me on your list for one? 2 Quote Link to comment Share on other sites More sharing options...
Ikrananka Posted August 21 Share Posted August 21 Great project. I'm curious to know if the colour palette on the PICO9918 is user configurable? Quote Link to comment Share on other sites More sharing options...

Well.. you can build the firmware with whatever palette you like, but not yet at runtime. I'm planning to add support for V9938 and V9958 soon which does support that, but also requires an additional pin to be wired up. Also, further support for some F18A features. 4 Quote Link to comment Share on other sites More sharing options...

Very good to know that the firmware can be built with whatever palette is desired, but a runtime utility to do this would be wonderful if that's possible in the future. If I remember correctly, aren't the NTSC and PAL palette's a little different - does the firmware account for this? 1 Quote Link to comment Share on other sites More sharing options...

It's using the NTSC palette. It's acting as a TMS9918A, so when placed in a PAL machine you'll get 60Hz, TMS9918A palette, etc. 1 1 Quote Link to comment Share on other sites More sharing options...

I'll definitely be grabbing a couple once @arcadeshopper has them in stock! Will be a much cheaper option than an F18A in my Tutor, for one. 2 Quote Link to comment Share on other sites More sharing options...

I have learned over the last 2 years to not sell things that haven't arrived yet it just creates stress on both sides and sometimes customs does something stupid and they dissapear once they are here they will be made available in the store first come first serve 8 Quote Link to comment Share on other sites More sharing options...
Gary from OPA Posted August 22 Share Posted August 22 was able to win on eBay, a nice HP 25" monitor with VGA and built-in speakers for only $40 loonies, so once it arrives, I going to put that monitor on my main TI99 system the one with v9938, as currently, I have only a tiny 17" on it, and then move that 17" over to my /QI console setup and installed the PICO9918 on it, and pack away the 10" CRT that I have curently on my /QI, for a future date when I build up a 4th system with only just original TI99 parts, which I have, i just need yet another desk, and another /4A console for it. 4 Quote Link to comment Share on other sites More sharing options...
visrealm Posted August 23 Author Share Posted August 23 Been a very busy week! All existing orders have now been shipped. My Tindie store is now temporarily closed while I'm away. I'll be back on deck in September and ready to ship some more. 😎 PS. Will be glad to not have to pick up a soldering iron for a week or so. 🤣 8 Quote Link to comment Share on other sites More sharing options...
+dhe Posted August 23 Share Posted August 23 Thank you @visrealm. I purchased a Digit AVPC when it first came out, and thought, 80-columns *REALLY* makes the TI feel like a real computer. Can one of the lucky purchasers display what their installs look like from inside the console to outside the case? 1 Quote Link to comment Share on other sites More sharing options...

This is something I'll be looking at soon. There are some great no cut mods made by @Ruggers Customs which should be suitable for this. 1 Quote Link to comment Share on other sites More sharing options...
RickyDean Posted August 24 Share Posted August 24 Well I have my Pico9918's going. The one v.3 I built and the v.4 that I got from @visrealm. Now I just need to get the other (4) v.3's done and it'll be great 5 Quote Link to comment Share on other sites More sharing options...
JasonACT Posted August 26 Share Posted August 26 I wanted to test out the speed of the GPU, so I threw together a test case which just loaded up @Tursi's Mandelbrot code and runs it 2 seconds after the first boot before going to sleep... https://youtu.be/mfiGvWce0l0 I think that's pretty fast (I did remove the instruction counter assembler, which is no longer needed.) 5 Quote Link to comment Share on other sites More sharing options...

About 5 seconds, that's not bad. The F18A takes 3, so that's damn close. Likely close enough to run most software. I was noting the above comments about palette - what F18A features are supported? Just the GPU? (All my software uses the GPU to detect presence of an F18A, so that'll matter to me. ) 4 Quote Link to comment Share on other sites More sharing options...
JasonACT Posted August 26 Share Posted August 26 So far, 80 column mode, and... now the GPU. Attached is my very small effort to get the F18A unlock code working, along with the GPU for real (not just a test case anymore, it runs the real Mandelbrot GPU cart). pico9918-dev.zip pico9918.zip Source code, and .uf2 build - using Pico SDK 2.0.0 and not my usual Arduino method - sorry no splash screen, I don't have the Python PIL library built on my machine. I've also turned off the CRT raster line effect, I hope nobody minds. 4 2 Quote Link to comment Share on other sites More sharing options...
visrealm Posted August 26 Author Share Posted August 26 I can't try it for a week or so. But, thanks.Grest progress, @JasonACT @Tursi One core is mostly (95+%) free to run the GPU and we have quite a bit of headroom on the render core for more display features. 4 Quote Link to comment Share on other sites More sharing options...

Cool, I hope it would be detailed enough to render one of my pen & ink drawings, that would more than impress me, thanks for the teams hard work.
