FFS Google. I only asked 'who said that they were standing on the shoulders of giants?'. Apparently you think that Isaac Newton, who famously lived in the 1700's and died in 1727, sent a letter to his buddy in 1975. JFC.

A screenshot from Google and their 'amazing' AI overview that states that Isaac Newton used the phrase 'If I have seen further, it is by standing on the shoulders of giants.' in a 1975 letter to his friend, Robert Hooke. 

Isaac Newton died in 1727. Robert Hooke died in 1703.

And for my next trick (or descent into insanity), a text based web browser on the Torch Triple X emulator. Ta-daa! It's barely more than a 'get html' function at the moment but I'm learning lots. And it's something to do as I wait for my new man cave (shed) to be installed..

The text of the html is shown in the window to the left of the emulator. Some of the source code for the very bare bones of a browser is visible to the right and underneath the emulator window.

It's Monday. The summer is almost over. You know what you need. A superficial description of of an ancient Unix PC emulator, and how I've fiddled with it after standing on the shoulders of the most excellent person who actually originally wrote it. crashedfiesta.blogspot.com/2026/08/when...

When is a Torch not a Torch? When it's an emulator....

The old hardware of the Torch Triple X is proving to be a little bit bothersome (it's a right old pain the rear) and I've made little progre...

So, Mrs Crashed's phone just emitted the national alert tones with a warning about the high risk of fire, given the current weather. My Motorola Edge 50 Pro was silent, clearly content to let me burn..... 😬😄

Been a bit quiet as we're on the move from Crashed Towers to Crashed Twouptwodown and discovering that 18 years in one location is a great way to accumulate enough pointless crap (i.e. non-retro computing related) to fill a small stadium. Warm, dry storage has been procured for the important stuff.

I have survived another orbit of the local star. To celebrate here's a list of stuff I've done to the Torch emulator: -vi now works(ish) -serial no. retained after first key disk boot -aspect ratio corrected -floppy .img support -improved terminal (tsh) -boot sequence colours corrected cont..

A great evening writing a wrapper for the very basic Unix terminal on the Torch emulator. Added some history functionality (previous commands etc) and managed to get su working via a tiny script (called tsu), and cd works properly too. It behaves a lot more like bash but isn't actually... 😁

I got a PS4 on day 1. I asked the man in the Sony Centre when I pre-ordered if they were doing a midnight launch. "Good god, no." came the unguarded reply. 😂 Anyway, I skipped PS5 for reasons. But I won't be doing PS6 with no disc drive. Licensing is not owning. See Sony/StudioCanal for details.

Checkup on the Cifer to make sure he's still working before I pop him into storage for a little while. I hope the Retro Overlords will forgive my use of hot glue to stick the front panel in. I spent hours 3D printing it but got the lugs in the wrong place and I was desperate. Don't judge me.

So. Good news and bad news. Good news - new limpet works and I managed to boot all the way in. Wa-hoo! 😁🥳 Bad news - my motherboard requires a startlingly big concave bend in it to work.... 😬 By chance I found if I wedged something under the right side it would boot. A weird mechanical bug....

The Torch Triple X showing a finished boot. Yay! The kernel window is shown in the middle and three icons are one the left hand side of the screen.A picture of the recreated limpet board with its LED lit showing data being transferred. A picture of the Torch Triple X terminal showing a directory listing of code files for uemacs.A terrifying picture showing the Torch motherboard with a screwdriver underneath on the right side (protected from the board by a plastic sheets). 

The end of the motherboard is wedged down on the right side by a large, heavy HP laptop, leaving the left side of the board dangling. 

In this configuration, the Torch boots successfully, every time. Eek.

Torch Triplex Limpet board looks great. And I found the second error. I missed a whole track that should link all the write enable lines on the DRAM. Oops. Bodge wire installed but it still doesn't work. 🙁

I might've caught the coding bug for vintage computers... After several hours I have managed to get 'vi' working on the Torch Triple X emulator. The stack is too small for when vi starts (something funky happens) so by making it bigger, vi then works. Nice. Next stop, proper floppy support.

A screenshot of the Torch Triple X emulator. It shows a text file called 'workingvi.txt' opened in a vi window. The file has 17 lines and 473 characters.

Managed to hand one of these to @binarydinosaurs.co.uk as the only other person I know in the country with a Torch Triple X. 😁 One of the four left is about to start receiving capacitors and sockets.... 🙂 ...and I found the first error. Oops. Capacitor C45 has both legs against ground. Darnit.

A yellow capacitor in the centre of the picture. A cut is visible in the trace between the bottom pad of the capacitor and a thick track. This cut removes the short between ground and +5v lines.

It's official. My Torch Triple X is no more. There is some fault with the limpet board which I can't track down. All RAM is OK. All tracks are OK (or repaired). I suspect a failure of one of the PAL chips which did get quite warm. Ultimate unobtanium. Without it, the Torch won't boot. Arse. 😢
