Well shoot, I think that does it. These little guys can download your photos from every one of the four WQV model camera watches, from tiny Game Boy Camera-like grayscale to 90s webcam-like crunchy colour JPEG, and pop up as a USB drive. Needing ancient software and unobtainable hardware: solved.

My SuperStation One showed up! Looking forward to seeing what all this MiSTer hype is about. #retrogaming

Thanks to @leadedsolder.com ‘s #x68000 pro pico psu pcb my machine has a nice and modern power supply! It also grounds the machine properly for the 5-15P cable that was used for power. I’ve been putting this project off for around 5 years so I’m glad to have it done!

If you've ever wanted to make a game for the Epoch Super Cassette Vision (tumbleweed passes) then may introduce SCeVe, a sort of SDK for it. It's written in, possibly, the worst way ever but it does work codeberg.org/Jonn-reenthu... #RetroDev

New blog post! It's part five of my quest to make my very own #ColecoVision. This time, I let other people build one too, and make sure I actually included all the parts! There's still some bugs to work out, but I do still love my first clone system. www.leadedsolder.com/2026/03/24/c...

UPDATE: BEEP has confirmed they are moving soon xcancel.com/beep_akihaba...

Every time it comes up I just gotta remind people that it's extremely expensive to license filming in Shibuya, which the team making this game couldn't afford, so they filmed this game by stealing shots and running from the cops.

Successfully opened SSH connection to my Linux box from my Panasonic FS-A1 #MSX via #FujiNet. This means network functions are working as expected. Now our apps can start to be ported. #retrocomputing

New blog post! A what-if scenario where we try to see how a home computer designer might've dealt with the field-sequential color television, had the Korean War not stopped that standards' rollout. Enjoy! nicole.express/2026/the-app...

New blog post! This TRS-80 Model 1 was found in the bottom of a trash bin, smashed to bits by heavy printers and cash registers above it. Will it ever run again? #retrocomputing #trs80 #tandy www.leadedsolder.com/2026/03/03/t...

New blog post! Fujitsu made a wildly complicated machine in the FM-77AV2, and this one defeated me. I did narrow the problem to a bad custom chip! Come along and see the heaviest 8-bit computer I owned before I got even heavier ones. www.leadedsolder.com/2026/02/10/f... #retrocomputing #fm7

This is pretty neat. Someone on AliExpress is selling a Soggy-1000, my open-source #Sega SG-1000 clone, with the 3D-printed case that keegs made. They even went ahead and modified an NES-clone controller to work with the SMS pinout. Hope they liked building it! #retrogaming #kicad #retrocomputing
