So now that folks are receiving their #Mega65 computers I ask: What is the first thing you will use your new #Mega65 for? #RetroGaming #RetroComputing

FPGAs, like those from #Xilinx are what made the #MEGA65 possible :) Nice write-up from Xilinx about how FPGAs are enablers for niche games markets, like the retro computing scene.

Thanks to the NLnet Foundation @[email protected] , the MEGAphone R4 PCB has been built, and core functionality (and the usual bunch of erata ;) confirmed: c65gs.blogspot.com/2022/09/megaph…

More work on the simple browser and BBS client for the #MEGA65 c65gs.blogspot.com/2022/10/workin… See video of the live-stream showing current progress at c65gs.blogspot.com/2022/10/workin…

Working on implementing composite video for the #MEGA65 using a custom-made expansion board. Mono first (this is NTSC), then once that is working for both NTSC and PAL, it'll be time to add the colour signalling.

#MEGA65 mono composite output now working: PAL & NTSC, interlace and progressive: c65gs.blogspot.com/2023/01/workin… Next station: Adding colour!

PAL Composite output now producing a good image on the #MEGA65. This is planned to be available via an expansion board for the MEGA65, that will also include user, tape and 1565 ports. NTSC is being worked on, too.

I've started work on an open-source full-size horse riding simulator machine. Why? You'll have to read the first post to find out :) opensourcehorse.blogspot.com/2023/02/why-do…

This is the game that I am supporting for my low-cost open-source horse riding machine: kickstarter.com/projects/minde… Support is unofficial for now. When done, you will be able to ride using hand, leg and seat aids, using real tack, like this: youtube.com/watch?v=cjcjPN… Unbridled: That Horse Game

More work on the hardware-accelerated IEC (commodore floppy and printer) bus for the #MEGA65: c65gs.blogspot.com/2023/12/hardwa….

c65gs.blogspot.com/2024/01/workin… Just been working on the tape port on the prototype #MEGA65 expansion board. Successfully loaded and ran the first game off the first tape I found :) Next is to confirm the user port on the expansion board is working.

Confirmed the user-port on the #MEGA65 expansion board works. Also designed some helper PCBs to avoid the need for cable salad. c65gs.blogspot.com/2024/01/workin…

c65gs.blogspot.com/2024/02/expans… next prototype of #MEGA65 expansion board is being fabricated now. Read the blog post if you're interested in the usual story of the progress.

Update: It works!!! We’re able to see a 2mm wide plastic ball at 30 centimeters, with only 1/1300th of our planned transmitting power. This validates our SNR budget and gets us closer to our final goal: tracking and killing mosquitoes at a 3meters range
