This isn't a new project, but it's new to me and very interesting. tiny-gpu, a Verilog implementation of a toy GPU.
New PCB rework!
This time instead of soldering on the track I used a short coil wire so the job is cleaner!
Applying the rework-fix on board #2 proved that board #1 io expander was burnt!
All (SPI+io expander) is good now on board #2 :)
BREAKING: Shure Axient Digital PSM has just won an NAB Best of Show Award in the MIX category!

基於 FPGA 的 LGP-30 複製品
➤ 回顧早期計算機時代的魅力
✤ https://www.e-basteln.de/computing/lgp30/lgp30/
這篇文章介紹了一個使用 FPGA (現場可程式化閘陣列) 複刻 1956 年問世的 LGP-30 電腦的專案。LGP-30 因其簡單的設計和相對低廉的價格，被視為最早的個人電腦之一。該專案旨在忠實重現 LGP-30 的位元序列架構和時序，並透過現代元件實現，包括使用 FPGA 模擬 CPU 和磁鼓儲存，以及可選的視訊顯示來呈現磁鼓內容。專案提供詳細的建構說明、所需檔案和工具，並具有 USB 連接埠及其他功能優化，方便現代電腦連接和操作。
+ 哇，這真是個令人印象深刻的工程壯舉！能用現代技術重現如此古老的電腦，太酷了。
+ 我對古董電腦很有興趣，這篇文章讓我對 LGP-30 有了更深入的瞭解，也激起了我動手嘗試的慾望。

Ordered an FPGA board with PCIe as I want to get some experience with that interface. Most are really expensive but I found an affordable Dragon board from KNJN. Let’s find out if it’s any good when it gets here.. #fpga #development
The PCB rework of this sunday afternoon :)
It went well!
FYI I don't have binocular nor a good soldering iron.
Had to scratch the track, unsolder the very small resistor, re-solder it on the track (from parallel to series).
It's a bit dirty I agree but it's done and it works!
Amstrad PCW is available for MiST too!

Triangle rasterisation is surprisingly complex. There are multiple approaches and decisions to make on which pixels to include. As part of testing my Earthrise #FPGA graphics engine, I've created visual tests to complement more automated testing.
While working on my #FPGA projects I've collected quotes and ideas I've found throught-provoking or inspiring.

mecrisp-ice on my iCEBreaker FPGA board. So cool. The first time synthesizing my own Forth CPU.
Thanks to Matthias for the Mecrisp project.

What do we know about the Gowin GW5A #FPGA (GW5AT-LV60P484A) found on the Tang Console?
Board pricing looks reasonable, but I'm naturally concerned about open-source support. I did see some discussion at Project Apicula last year: https://github.com/YosysHQ/apicula

Apparently, someone thought it was a good idea to write a tech novella on #GitHub about connecting #Legos (Xilinx FPGAs) to a Game Boy printer via PCIe voodoo.
