Audio-in mod on Amstrad CPC 464 based on Noel’s Retro Lab approach seems to work well. Next up add tape drive control signals … 🎶 🕹️

Will I fix this before every chip is in a socket?

Hello World! (It works!)

This one is from Age Concern charity shop. Had bad power, but turned out to be leaked battery damage and a sketchy power brick - bargain! 🤩

The new ultimate c64 is nice and all for existing c64 stuff but what would be really cool would be to do like ZX Next and add a more powerful mode/core .. 256 colours, more sprites, blitter, more scrolling layers, two sids

Anybody else remember when - occasionally - something cool or good used to happen? I swear this is real

Woot my scope works on uk 🔌

It’s overkill, over priced, and over complicated for 8 bit computers (underpowered for ESP32 and Pico at full MHz, though) but it’s saved me from a lot of desoldering over the years 🤩

Amstrad NC100 now has power but had to order a replacement ribbon cable to hopefully get the screen working 🤨

I did guess the fact all he needed to do was put some batteries in that untested meant broken 🤭

Could have given it a wipe down though, it doesn’t show in the photo but it’s filthy. Going to need a good bath 🧼

Perhaps I should stop buying broken computers and start fixing them 🤔

Well that seems like a solid approach. A+ pro tip 🌟
I've found that reporting these idiots with "farming for Steam points" gets their posts nuked.

Meanwhile, reporting for racism / queer phobia? Crickets.

Bridging connections should simulate a key press right?

Which means something is borked on the main board?

Then: "Why is it taking sooo loooong?? How hard can it possibly be?!"
Now: "Oh. Huh. Ah well, ship it anyway."

See also: "It works for me" has moved seats from the developer to the client side now. Sorry, but all your clients are not going to view it from some middle manager's laptop.

These permanent breadboards from pcbway came out amazing! It might not look like it, but just like a regular breadboard the power rails and columns are connected - much more convenient than perfboard
