1988: 8 year old me waiting for screeching cassette tapes to load on the #Amstrad CPC464. 2026: 46 year old me feeding a ROM into AI and playing an original 8-bit inspired browser game in less time than the tape ever took to load. That curve is hard to grasp.

Where has all the RAM gone?

I’ve been looking around for a while for an old butler sink for the outdoor kitchen I’m building. Yesterday one of my neighbours got rid of one, which would be great on its own, but this sink is originally from the British Museum, making it awesome.

In light of what is happening in America in 2025, it’s staggering how accurate Back To The Future II really was.

This still looks like a solvable problem. The energy requirement is going to be the major limiting factor to AI for quite some time, not the capability to reason.

Number 1. On my list of dangerous/untrustworthy tools, the Router. Someone looked at a vertical milling machine and thought, awesome tool. Let’s take the head off and replace the 1 tonne of cast iron stability with two plastic handles. Plus in the US it’s pronounced router, and in the UK router.

Vibe coding computer games with my 13 year old son to see who can make the best spaceship lander game. Son is currently winning.

Bit of SMD soldering this evening. Not bad for a first try. I hope this custom addition to my #Amstrad 464 Plus works.

Wouldn’t it be cool if you could use a local LLM on an #Amstrad 464 Plus? Hold my beer…

Interesting, two completely different answers from GPT-4o and GPTo1 regarding Raspberry Pi’s Compute Module IO board schematic. 4o tells me to modify my custom PCB circuit or it’ll lead to complete failure of the PCIe link. o1 is totally cool with P/N swapping on a PCIe pair.

Currently learning KiCAD by designing a custom RaspberryPi compute module base board for my Amstrad 464+. I haven’t designed a PCB since college. Fingers crossed…

Reverse engineering missing tape lid on an #Amstrad 464 plus. For my 464 plus Raspberry Pi project. Modelled in #Fusion360 Printed on a #Bambulab A1 Mini.

Yep, I definitely think I can retro fit something else in this Amstrad 464 plus. Might go for a #RaspberryPi compute module on a custom PCB, hence the templates. Add a #PicoPi to share the keyboard input, pull power from the main switch, fit Ethernet, HDMI, and USB ports on the right of the case.
