I've learned about side set feature of PIO assembly.

Some more progress on designing for TP700C enclosure.

Gemini CLI's chat pane shows up on the left on VSCode. I often want to navigate between files while keeping the chat window, and is quite cumbersome.

Thanks! Vee seems like the one - I'll check the voltage range of this. It could be on the mother board side, or could be on the panel.

From a lower angle, I can see it little better, but still hard to read. The polarizer looks okay, so something to do with the LCD circuitry?

The issue is the liquid crystal side. I can barely see the characters.

Zeos Notebook 386 - The LCD panel's CFFL was fine. I can see the light.

Yeah, the rubber belt is stiffen and not quite conveying the power to the gears below. How I can find a replacement....?

The microcassette is H: drive. It spins up, but the tape is slipping and it shows "DU Error".

Microsoft basic version 1.0 on EPSON PX-4 from 1985. #retrocomputing

EPSON PX-4 still works! Make sure the AC adaptor's polarity. It's center-negative.

It's always very difficult to identify which connector is used in an old board. I was closely looking at it, and realized that there was something. It turned out that it says "HRS". I believe this was Hirose's DF13A-15P-1.25H.

I was able to restore IBM ThinkPad 760CD! It has full 64MB RAM with a nice TFT 800x600 screen! #thinkpad #retrocomputing

making progress on a 3D model of a ThinkPad 700C panel.

X68000 mother board has a shield cover. The white screws are for itself. The yellow screws are to tie it down to the chassis.

OpenAI’s new GPT-4.1 AI models focus on coding OpenAI on Monday launched a new family of models called GPT-4.1 . Yes, “4.1” — as if the company’s nomenclature wasn’t confusing enough already. There’s GPT-4.1, GPT-4.1 mini, and GPT-4.1 nano, all of which OpenAI says “excel” at coding and instruction following. Available through OpenAI’s API but not ChatGPT, the multimodal models have a 1-million-token […]

I thought CLK is always consistent, but I've observed some gap every 35.6Hz (every 28msec). Interesting. #x68000

My X68000 is not booting up. However, the CPU seems to be successfully bootstrapping.

Some more progress.

The OTI054 chip used in a Zeos notebook was a part of Oak Horizon chipset.

These 3-leg components are marked as TDK 222, FL045,etc. on the board. - EMI filters / feedthrough capacitors (2200pF?)

working on a new part.

Some tracing done.

I'm using an RSS reader called NewsBlur - www.newsblur.com

Made a battery for ThinkPad 755C. It's a little bit thicker than the original.

Let’s Make A Space Shooter With Nintendo Family BASIC Nintendo’s Famicom game console had an implementation of the BASIC programming language available for the system. The Family BASIC cartridge is studied, and a space shooter game is programmed with it.

New blog post! We're taking the Famicom to OUTER SPACE in an interstellar adventure of BASIC programming. But first... did I buy a broken cartridge? www.leadedsolder.com/2025/03/11/f... #famicom #nintendo #nes #basic #8bit
