Hi David. Did you find the time to get a UPDI programmer up and running (for the AVR)?

Just thought I'd let you know that the github repository (CreatiVisionMechanicalKeyboard), has now been updated with all the v3 resources. I've also retained the v1.0 code, by moving it into a v1 sub-folder.

Also, I've now updated the Tindie Store listing for v3 (now that I've received the v3.0 PCBs).

I'm just now completing my Blog and Youtube video covering the v3 upgrade (including demonstrating my existing v1.x PCB upgrade), which should be published this Friday evening (your time).

Thanks for leading me on this fun (and educational), upgrade journey!

Greetings Greg, I've yet got a programmer for the AVR, I did her that Microchip have a new low cost programmer available but they are out of stock so I put that idea on hold for now. I can get by with patching the PS2 receiver code for the time being. I'm exploring the AIM-65 possibilities these days and about to embark on a 6845 video interface as well. Looking forward to seeing your video, how about showing your darts scoreboard too? Best regards, David.

If you do get a different / cheaper UPDI programmer, just make sure it also supports the High-Voltage UPDI v2 mode, needed for some newer device applications (e.g. my AVR EA use in the CreatiVision Controller).

I also have the cheaper MPLAB Snap programmer, but it doesn’t support High-Voltage UPDI mode (and it’s a pain to switch between AVR and PIC modes).

Interesting to see how you go with the MC6845. I also played with these in the early days, so I still have some somewhere in my parts collection.

Making a 6845 CRTC Display card was something in my longer term plans (as well as a NEC 7220 Display Card, which I also have fond memories of).

LOL. My better half said I’d probably get a request to make a video about my automatic darts project.

Unfortunately I wasn’t in “project recording mode”, so I didn’t even take photos of my progress along the way.

I should have been, as it was a fun project involving everything from AliExpress parts, a Mini-PC choice with various OS install options explored, some 3D printing, and also some carpentry.

A great summer project, that I now enjoy every day!
