One of the easiest vdp replacement options

For PICO9918

I have been using various FPGA based vdp replacement options for years. The pico9918 board has the right form factor, and the right price. The creator of this little unit has leveraged his long experience with the TMS 9918 emulation to pack all of that and more into the rp2040!

I use this device on my own homebrew boards and have tested it successfully as a replacement option in the Nabu and on the z80-Retro by John's Digital Basement which uses a Tms9118.

The other main benefit for me is that with these (and other) replacement solutions, the supporting components are also emulated. When using the pico9918 designers can skip the xtal and dynamic ram components which massively simplifies new designs.

If you're looking to replace your existing vdp for better video quality, or you're working on a new design, I absolutely recommend the pico9918.

Awesome device - Works on Many Systems - 2024 Upgrade

For PICO9918

Upgrade these classic systems to 2024 technology and crisp clear VGA output! I've installed two of these now, one in a Coleco Adam and one in the TI 99/4a. They are easy to install and take up no more room than the original chip. Plug and play out of the box, get a industry standard VGA output. Quick shipping and good customer support. Troy has been good about keeping the community in the loop on when new shipments will be available and updates to the firmware.

A great project and a perfect replacement for the TMS9918

For PICO9918

A great project and a perfect replacement for the TMS9918. A well documented Github and the project is still under active development.

Does what it says on the box

For PICO9918

Just plug it in and it works. Great product in its current state with more features likely to come in the future.

New life into my old TI-99/4A.....VGA output!!!!!

For PICO9918

Thanks Troy for starting this project. As a PAL TI owner I was suffering with poor video out, the composite mod (tap off the modulator) didn't really help. When Troy posted his early efforts on the TI Facebook channels I had to have one when it became mature enough for a proper replacement. The PICO9918 is definitely mature enough, works perfectly as a replacement for the hot running 9928 and with the additional efforts Troy's doing on adding F18A support etc the future's bright for the old '99.

Everything is perfect

For PICO-56 Kit

Received it today and built it already!

Worked from first power on, kit was easy to build.

Just small remark - better grab NES gamepad before running software - you can't ever run most of them without gamepad.

My time lapse of building: https://www.youtube.com/watch?v=3sYh3xi-5vY

Excellent kit

For PICO-56 Kit

Haven’t tested it yet, but I’m almost done assembling it. There were some issues customs but Troy quickly sent me another one before I even knew anything was wrong.

The kit is clearly labeled and assembly is very self explanatory.

If I had any suggestions it would be to include some extra resistors.

Thanks Troy!

Great kit, easy build

For PICO-56 Kit

Came with all parts labeled and board with part labels too. Very easy to build. works great! Would love to have a 3D printable case (hint, hint)

Hi Michael. Thanks for the review. I now have a case available. STLs on GitHub. :)

Pico-56 - A great easy to build retro computer kit

For PICO-56 Kit

I ordered the kit with two Nintendo controller ports & opted to solder the micro-sd card my self. I followed along with build video which makes the build super easy to complete. The micro-sd card was in the end easier than expected and the video covers the process very well. The kit is easy to assemble and went together in about 2.5 hours - and it worked first time too.

The build video covers the process of installing the firmware on the Pico which is super easy and then takes you through the process of copying the current software library onto your micro-sd card. The demo software all worked perfectly and offers a fun way to see what this little board can do.

Get yourself a Pico-56 - you will not regret it!

Works as described.

For PICO-56 Kit

I got the assembled version. Looks professional, works fine!

Well packaged, arrived in good order and quite fast from Australia.

Lots of fun ahead!

A great little computer

For PICO-56 Kit

I built my PICO-65 over the weekend, and I'm really impressed.

This is a very easy all-through hole kit (really glad the SD card is pre-soldered). The components are all labeled in their bags and on the PCB silkscreen so there's no issues placing and soldering everything. You can complete the entire build and be up and running in an afternoon. I've have to test it a bit more (where are my NES controllers?) but I loved the ease of flashing the Pi Pico and getting right into it.

As far as retro-style computer projects go this is a FUN one. Pick one up when they're in stock.

Pleased to have this kit and looking forward to more.

For PICO-56 Kit

I was able to build this kit quite quickly, although the SD card soldering needed touching up as the pitch is fine. The software works and there are sample roms to play with. The software development environment is still to come but it will likely follow the HBC-56 pattern. The software (version 0.2 at the time) could be better advertised on the github page as it was not in the main github section but off to the side under the releases area. I'm looking forward to more of the Youtube videos and code for setting up the development area and following some of the examples. I hope to add some 6502 code examples when I get up to speed. While you can order bare boards and build your own, the kit has everything you need and the price is reasonable. My only complaint is the shipping cost versus the package cost but that's what you have to expect when you live in Canada and have to pay in US dollars.
