I'm to be very busy in September, including traveling to and speaking at the MicroLED and AR/VR Connect conference in Eindhoven, Netherlands, from September 23rd to 25th. If you would like to meet with me in Eindhoven, please send a meeting request to meet@kgontech.com.

I also want to let you know about an interview I did with The Voices of VR Podcast at AWE 2023, which was released on August 2, 2025.

TMS9918, The First Sprite Chip – Presentation at VCF SouthWest

Last week, I gave a presentation at The Vintage Computer Festival Southwest (VCF SouthWest) about the development of the TMS9918 (and related devices), which I helped define, design, simulate, and debug from September 1977 through mid-1978. In addition to the presentation, I participated in a one-hour question-and-answer session hosted by Matthew Hagarty. Matthew has developed a series of FPGA-based 9918 emulators, the latest of which is pin-compatible except for providing R, G, and B output rather than composite video.

Exclusive – Playnitride Single Chip Full Color MicroLED & Lumus Waveguide with a “Fantasically Tiny Projector”

Several technology demonstrations stood out to me at Display Week (DW) 2025. This article will cover Playnitride's Quantum Dot (QD) based full-color MicroLED, combined with Lumus's geometric (also known as reflective waveguide) technology.

As I wrote in may last article, Lumus showed me a "fantastically tiny projector" connected to their waveguide.
