# Timex Sinclair Online User Group Meeting December 21, 2025

## **Peyton’s Holiday Program Demo**

Peyton responded to a seasonal programming challenge by demonstrating a Christmas program from **[Synchro Sette](http://localhost/category/periodicals/synchro-sette/)** magazine (Volume 2, Number 11, December 1983). The program featured animated graphics with typing sounds and a fragment of a holiday tune.

Peyton also worked on the [Vintage Computing Christmas Challenge 2025](https://logiker.com/Vintage-Computing-Christmas-Challenge-2025) to create a snowflake design. Version 1 was a Basic approach with direct coordinate plotting, version 2 was optimized using AI (Gemini) to make code more efficient and compact.

### **Sound Chips**

We had an extensive conversation about sound chips for the Timex computers, noting that =the AY sound chips (8912/8910) becoming rare and expensive. FPGA emulator versions and the Yamaha YM2149 chip are available.

### KiloZed and 3D TS 2068 Case

Ingo gave us an update on his Kilozed and testing Carl’s super-1000 board; Peyton showed us a 3D model to the TS 2068 case he’s been working on.
