I've ported the py65 engine core to Typescript which greatly improved performance. I've also developed a Debug Adapter which allows debugging within Visual Studio Code. More detail at my Github db65xx .
For testing, I've just directly run the Klaus Dormann 6502 functional tests. This misses the ...

Re: Current 6502 Kits
I guess there are two types of kit. One is the "electronics for absolute beginners" type where you get a breadboard and a bag full of components and you build your projects without soldering.
The other type is where you end up with something more permanent, which will require soldering.
To me ...

Re: Current 6502 Kits
Surely anyone who buys an electronic project kit would expect soldering to be required? Tongue in check I guess. Here's the first kit I bought for my girls. IMG_20230312_143202329.jpg It wasn't until many years later that I bought a soldering kit for them, mostly because my youngest said she should ...

Re: Current 6502 Kits
But what I really lusted after was one of those 100-in-1 project kits as shown here: https://www.radioshackcatalogs.com/flipbook/1976_radioshack_catalog.html?fb3d-page=92 I saved up my paper route money and bought one of those.

Re: [ca65] Placing words at specific locations in segment
Try using a macro that takes the ascii character and jump address as parameters. Have the macro keep track of the current position (using the set command) and use the repeat control command to fill in the empty entries up to that point. So something like this: .macro jmptbl char addr
.repeat char ...
.repeat char ...

Re: Ben Eater's Reset Circuit
I saw that too. You can hear him pause just slightly at that point as if he's wondering whether to explain it or not.
If you look closely at the build in the video, you'll see that the reset circuit doesn't have a capacitor, even though it's there in the photo and schematic on his website. It's ...

Re: Current 6502 Kits
In the case of a certain, well-known Youtube hawker of 6502 kits, support is minimal. That’s why we have people signing up here and posting, “I built Ben Eater’s 6502 kit and it isn’t working. Help!” :D It's a business decision which doesn't seem to have affected his sales. Ben set up a reddit ...

Re: Newbie to the 65816. WDCtools C compiler and debugger is
My impression, as I view them from a distance, is that As65 is far better than ca65. A closer look might be worthwhile for those wanting more features, control and flexibility in their assembler. The downside? It will take longer to get up and running with ca65. I especially like that ca65 gives a ...

Re: Newbie to the 65816. WDCtools C compiler and debugger is
While I use cc65 on the 65C02, I've not tried any C on the '816. I've spent some time recently using cc65 for the '816. The C library doesn't have a '816 target (and if fact only somewhat utilizes 65c02 features) but you can run programs on the '816 in emulation mode. It's not hard to create a ...

Re: Looking for potential schematic corrections
If you're going to redo your schematics, consider using bus wiring for the address and data busses. It will make the schematics more readable. Here is WDC's 816sxb board schematic as an example.
