I blogged about this extended 80 column screen across two monitors for Commodore 128. https://t.co/ZI9WLZpNH3

[David Van Wagner @DaveRVW]

Commodore 128 supports dual monitors, so why not extend the 80 column screen across the two? Don't mind the speed, you make up for it in wideness. https://t.co/7pl0d2qPMN

And the C128 VDC background/foreground color cells plain as day... that circle is still there, just a bit overpowered by the colors

Have Commodore 128, check (since 1987). Bought to do high resolution graphics. Hmm, not yet but since it's 2026 I'm sure AI can help me do that, right? Spoiler: not quite. https://t.co/UekyyGBpbf #AIFail

8x8 color cells are available too if repartition 64K memory

Integrated BLE controller support as alternative to the cute @M5Stack keyboard. (I just integrated/adapted... everything else someone else is reponsible for.) https://t.co/XI79jsVbbx

@mrdoornbos What's your favorite core? Besides C64.

[David Van Wagner @DaveRVW]

See if your game controller can pair with @EspressifSystem ESP32 by using this test app https://t.co/RPRibYpDqE on M5Core or M5CoreS3 @M5Stack

It's not just another pretty face.  Time to get serious about retro gaming.
Up, Left, Right, Down, Fire (M5) and 2nd (click joystick).  Not just a d-pad, also mirrored pots so can do paddle games, or analog joystick games. Go play some games! https://t.co/uDC482TGrX @M5Stack

@AmazonHelp Amazon web help was no help went there first. Making a fuss here. Waiting for the class action lawsuit of no notice.

@AmazonHelp Now I'm paying $4.99/mo for Prime Ultra but I was never warned. When did you send the email? I see nothing relevant in my automatic Amazon folder with keywords Ultra or Ads. Did you miss me?

Are you allowed to just start charging more without notice. NO NOTICE!?

[David Van Wagner @DaveRVW]

@AmazonHelp Thanks for the link to NAMessageCenter. Learn something every day whether I want to or not. I see it there March 13. But not in my personal email that day. I didn't know about that message center.

[David Van Wagner @DaveRVW]

@AmazonHelp When you promise 2-day and same-day delivery, you should probably work with your shipping partners and suppliers and get them to NOT send state to state at ground shipping, and socal to norcal with USPS. I thought for sure you knew something about shipping by now.

[David Van Wagner @DaveRVW]

$2 more for 4K? @PrimeVideo @AmazonHelp I bought the Amazon Fire 4K TV January 2019. You start charging more 7 years later? First ads, now 4K. You're not Netflix!

Customers want a deal, not an extra charge. Think about good will and benefits. Not $$$$$$$$$$$$$$
