Update v1.2 for the RPi Pico Timex Datalink adapter, fixed watch sync issues I had in Windows 11 that probably affected others https://github.com/famiclone6502/DIY_Datalink_Adapter

“Everything you’ve heard is obsolete.” A very bold claim, but this sampler CD was enough to convince my family that we had to have one in 199x. It “converts” stereo into “3D surround sound” using only 2 speakers or even mono to stereo. Works with music/games/movies/anything. Unfortunately I didn’t find the power supply and there’s no voltage/polarity markings, so I’ll just have to wait to see if I’ve been missing out not using it this whole time. At least the CDs still work.

It’s alive! 🥳 Got 1 of 2 dead #Commodore #SX64 machines to boot. Saw cursor not blinking at #BASIC prompt could be loose IO board, & it was! Passes diagnostics, but #SID is missing instruments & internal speaker isn’t working. Disks unstested.

The other #luggable #C64 has many problems. Makes horrible speaker noise, disk drive spins, and garbage on the screen. Disconnecting IO board gets a white screen, which may be a bad PLA. Also has a custom ROM! 🤔

I need to order parts!

I had a spare #Coleco #Pacman tabletop that had a bad display and corroded board… didn’t have the heart to throw it away, so I’ve turned it into a tiny #emulator machine using this #ESP32 project: https://github.com/harbaum/galagino

Super #GameBoy clock #mod successfully installed! I also added a link port, so it’s essentially a SGB2 now.

Here’s the kit I used: http://www.qwertymodo.com/hardware-projects/snes/super-game-boy-clock-mod

I was hoping the #c64 DTV would be an easy weekend project after finishing the #harlequin128k #zxspectrum …USB power is working, but no keyboard seems to work with it. Info on modding it is getting more scarce, and mine is not as common (early NTSC version).

Well it looks like I’ve failed, just getting a garbage screen. Reseated all the chips, cleaned the board some more, no luck. I’m wondering how optional the diodes and resistors are for the joystick, maybe I need to solder those in too? Any help/ideas would be greatly appreciated!
