Progress! I’ve found my stepdown transformer and the Northstar powers up 💪🏻
Bonus, none of the tantrums went up either.
Now, has anyone seen my venerable DEC BC22D-25 serial cable so I can run a terminal? 😆

Afternoon off, so why not get the Northstar Horizon out for some board pics. Why not indeed.
This is a 48k machine thanks to the 3x 16k boards, and there’s a floppy controller for the Shugart 400 floppy drives.
I can’t power it up because it’s 110v and I can’t find my stepdown transformer 🙄 /n

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 😄

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 ...

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 😄

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.

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.

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.

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.

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
