Very old thread, I know, but I've only just come to MoM.

Lurkio: you're evil. The palimpsest clue is utter genius.

There's now a dtoverlay for shutting down the Pi - I think it was added in Raspbian Stretch. Add this to your /boot/config.txt dtoverlay=gpio-shutdown,gpio_pin=17 - I think I used Pin 17 but can't remember off the top of my head - you can use any active high GPIO pin for this. Grounding pin 17 on th...

I had one BITD which was Air On A G-String, and was the music used in the UK in adverts for Hamlet Cigars. I recall the screen slowly filled up with cigar smoke as it played. I haven't found that disc yet but it must be somewhere.

I would try searching for an engineering menu option for your TV. Yeah, been there, done that. I even cracked and got the manual out (that's how bad it got). It seems there are advanced options for every input apart from SCART. To be fair, this is all your fault. I'd never have noticed if it wasn't...

There you go, I knew someone intelligent would be along soon.

The Gotek can only read disc images ("image" in the sense of a virtual copy of a disc), so you need to get your picture onto a virtual disc which you can then load from the Gotek. Now, how you get your picture onto a disc image - that's something I'd like to learn myself. I've had a brief ...

JSBeeb.

Download the disc, go to the link above, select "discs" and open your local copy of the DSD.

shift-F12 to boot it (shift-break on a beeb).

The shopping list is here https://stardot.org.uk/forums/viewtopic.php?f=3&t=20751&p=291476#p291476 It’s actually not that hard - if you’ve got some basic skills with the Pi you could do this fairly easily. Mine was complicated by adding an automatic safe shutdown of the Pi, but if you’re wil...

A bit box is an enormous box of junk that my wife keeps asking me to throw away, but I keep in case I ever need something random from it: over the years I’ve added approximately ten thousand bits of junk to it, and used exactly three bits of junk from it...so I think you’ll agree it’s a useful thing...

I put my beeb online using a Pi Zero inside the case - works well. I think the PiTubeDirect uses a bare-metal code base so there's not an operating system you can even add to. My box has two Pi Zeros inside - one for the tube, one for the WiFi. I suspect that's your only way of doing it, to be hones...

Yeah, they'll be perfect. Those round MIL connectors, we use a lot for industrial applications at work, and they do work very well.

I've never heard of a "lugged connector" before - looks like it'll be a good solution for you. Let us know how it goes!

Could you make up some intermediate connectors?

(I’d still love to understand if it’s the beeb hardware, or the TV, or what...)

It doesn’t

So, this trick worked, thanks! Obviously it’s not permanent, but it’ll do nicely until I work out why it’s happening.

I guess for things I use a lot I can just add it to the !Boot.

I feel slightly stupid asking this question - but I've been trying to sort this out for days and I can't do it. My beeb is connected to a widescreen LCD TV with an RGB to SCART cable. All working nicely, except the top...probably...6 pixels is off the top of the screen. This has no operational effec...

It was just to amuse myself really

Get your laughs where you can, I suppose.

I found it funny...but we are all a self-selected bunch of geeks here.

I asked the same question a while back, and got the same answer...but... I noticed on my beeb, after being left on for more than half an hour I was getting a blocky "sort of corruption" on the top half of the screen - nothing that would stop you using it, but noticeable, especially in Mode...

For less than a fiver and an hour’s work, your boot and <Break> screen can look like this......

Well...shoot. I thought I was coming to the end of my hardware hacks. Thanks a lot, Martin.

I think I'm on something like 12 different working retro systems now, something like that, and a ridiculous collection of Atari carts. Also, against all the odds, still married after 20 years, so...

I imagine this may have been posted before, but I just discovered this: https://www.bbcmicrobot.com/ Some really elegant code being displayed on there.

Meant to say - Would something like a modded boo-bip EEPROM adaptor be of use? Yes, definitely. Once you have one you wonder how you ever managed without one. I've got all my ROM images in 27C512 EPROMs in the BooBip adapters (4 ROM images per chip). For the price - one of the best upgrades you can...

"Maybe I should look for a second machine to keep as a spare in case something goes wrong"

Careful. That slope is slippery and long. Very, very long. So long.

The tri-rail Meanwell RPT-60A supply is compatible with the beeb as it has +12, +5, -5v, but for what you want I'd guess a dual rail 12/5v power supply would work as I doubt the Torch needs -5v and the drives definitely don't. If you need to put the fancy beeb aux power plug on it, and can't fine on...

Check you've not got an off-by-one error on your keyboard connector.

I had something like that symptom (IIRC) when I put the connector on one pin out of line.

If I keep buying stuff for the beeb at my current rate, I won't live that long. Mrs. S has assured me of this.

Oh, I hear you. Knowledge is beautiful and relevant in and of itself. My problem is, as I advance into my mid-40s, every new bit of knowledge pushes something else out and since my brain operates on a FIFO buffer, it's currently 1st year university stuff that is being sacrificed for esoteric facts a...

Had 3 separate eBay things go missing recently, one with Yodel, two with Royal Mail. Thankfully all small and not particularly important, but it's frustrating nonetheless. Anyone else having problems with stuff being posted?

I've got a new batch of these boards in if anyone wants one.
