This is exactly what happened with the drive in my Acorn R140, and attacking it with a magic eraser obviously didn't occur to me. I just put the top back on with a sigh.

Guess I need to get it out again as Technight is right - I have nothing to lose.
Lithium battery fumes got inside the HDD and oxidized the platter. I actually was able to clean this off with a magic eraser AND IT READS... Plenty of bad sectors, but i am getting an image!

Speaking of RIFA madness, I’ve been collecting every non-exploded one I’ve pulled out of PSUs over the years. Every summer I say I’ll wire some up and slo-mo film the detonation and every summer I fail to do this.

Next year eh.

Sorted out the Beeb PSU that smoked during RetroFest last weekend. It blasted the incoming mains cables with its guts, which took a LOT of cleaning up. Tsk.

Something I wanted to test before RetroFest was this Toshiba HX10, aka the only MSX that really sold in the UK. A common complaint about them these days is that the keyboard no longer works and I had a clue as to why when I was refurbishing my Sony HitBit HB75.

First though, the machine.

Post-RetroFest tidying continues, and we dig out the Commodore CHESSmate complete with crimes against plug wiring. I need another bag of 3A fuses now.

History of the CHESSmate is here, from the designer himself. benlo.com/microchess/c...

Oh wow, I've been meaning to do this for literally years!
TIL that there is an open source hard drive emulator for the Atari ST line of machines. How freaking cool!

What a splendid weekend! Thanks to @computinghistory.org.uk for hosting, @heredragons.be for organising and everyone who came to stop and chat! Winner of the Beeb high score was @snuggsy187.bsky.social with a frankly ridiculous 237110, and the Speccy was @morefunmakingit.bsky.social with 23030 😄

Of course, @binarydinosaurs.co.uk hatched a plan to have most versions of Chuckie Egg on his table.

Well, those scores have increased a bit! And the shock of the weekend was Nicholas getting 64 on Flagon Bird - which we think is the highest possible score! Come see us tomorrow at @computinghistory.org.uk and see if you can do better ...

Hell's teeth, one of my favourite ever games. Hard to believe it's 26 years old!

UNSTOPPABLE!
Unreal Tournament can now be played IN A BROWSER

Along with other late 90s PC FPS classics but yeah. UT99 in a browser window... just fantastic. Thanks to the r/LGR subreddit for letting me know about it!

Ready to röck your Chuckie Eggs at @computinghistory.org.uk this weekend. That poor little Spectrum being dwarfed by the bigger machines is my original machine so be nice to it 😄
November 14, 2025 at 7:04 PM
Just for lols I’ve added the Toshiba HX-22 as a backup to the Sony because it has a great picture in, surprisingly, RF mode.

The LG monitor shown here is not in RF mode, it’s composite.
November 12, 2025 at 6:23 PM
Any MSXperts about? Is there such a thing?

I’ve tried three (3) different machines (Sony, Sanyo, Toshiba) and they all have the picture slightly offset to the left.

Not an issue for the weekend, I’m just puzzled cos it’s clearly either a) LCD issue or b) VDP issue.
November 12, 2025 at 5:52 PM
I still have my original 48K Speccy that I saved up for ages to buy this SAGA 1 Emperor keyboard for. Today it fell to bits. At speed I grabbed my other Emperor keyboard to find it too has fallen apart.

Curse these manufacturers not thinking their products might still be used 40 years later 😆

Sony HitBit HB75 reporting for Chuckie Egg duty now it has a refurbished keyboard.
November 12, 2025 at 11:28 AM
Acorn Atom now has a turbo mode, AtomMMC2 SDcard adapter and all the classic games work!

Apart from Chuckie Egg which seems to think it’s in joystick mode 😆 #retroGamingFest25

Arses. It works fine in ‘slow’ mode but there’s a lot of snow on the screen as was the case with most Atom games.
November 11, 2025 at 7:25 PM
Dust bunnies!

1980s filth!

Almost a shame to clean it, but it’s CAKED.

Mmm cake.

I love finding build faults in nearly 50yo machines. This seems to have been like this since new. Good job nobody has tried to get a printer working on this Acorn Atom!

Without a 6522 fitted to the IO socket this won’t upset the machine, but guess who’s just fitted a 6522… 😆

I've seen mentions of this and the occasional project update, but not what the finished form looks like. This looks *great*
Are you ready for #PicoIDE? It seems to be telling me it's ready. Coming soon: ATAPI optical disc emulation and IDE hard drive emulation. picoide.com
November 10, 2025 at 10:51 AM
I'll be the one to add the missing word - 'week'. Insert where you see fit, then come and see me exhibiting some Chuckie Eggs on as many machines as I can fit on my table* 😁

Join in to decide which is the best version!

(*4, at a guess)
Oh wow, this time next we'll be in full swing! Tickets for the Saturday are close to selling out - www.computinghistory.org.uk/det/74558/Re... - alternatively, Sunday will be quieter, but still the same wonderful exhibitors - www.computinghistory.org.uk/det/74909/re... - see you all next weekend!

Result! After a lot of faffing with different TANBUG versions trying to get things to work properly, I discovered the second TANEX board wouldn’t function properly in my working Microtan.

Answer: pull the RS232 chipset!

Suddenly, TANDOS works properly 😁
November 9, 2025 at 3:11 PM
Huh. For those following the Microtan saga I pondered that the keyboard I got with the machine wasn’t a Microtan keyboard.

Turns out that if you feed it -12v and its own GND connection it only bloody works fine.

TANDOS board next, in that case.
November 8, 2025 at 4:10 PM
OK, so this week's tale of woe was a non-booting Microtan65 + TANEX expansion. Zero activity and the mysterious case of a clock signal being flattened. Voltages at the header looked good, yet the thermal camera showed a very dead looking board. This was backed up by scope traces showing nowt. /n
