Commander X16 Proto #2


Recommended Posts

Hi again! I've been working for quite awhile to get the new layout complete, and I think we are just about ready to run the second prototype! There are quite a number of changes to this board over the previous version, so I do expect a few, ahem, challenges perhaps? 1f642.png🙂 That said, a lot of time has been spent testing on breadboards and optimizing so I think we should be close to the final specs on this system. As mentioned, there are code breaking changes with the system. I will post more for the devs out there in a post below. The VERA has also changed quite a bit. Namely, it now has 32 registers, but I'll let @Frank van den Hoef talk more about that when he is ready to post some updates. Also, I made two proto boards to test the bus and get the alignment right for the final design. Progress is being made, thanks for everyone's patience and have a great day!

Dude this is thrilling to see! I saw your post on Facebook first and figured I'd poke over here a bit. I did want to know if those prototyping boards were going to be shipped with the system as a bundle or sold separately. If it was considered to be bundled with it, would it just be the S boards? Also, what would the prices be if you decided to sell them?

This is so much better than reading the same post on FB 🙂

Agreed! In future we'll try to only make announcement posts here, then paste the link into FB (which will generate a preview of the post anyway). The website will be the go-to #1 source.

Y'all know PCB stands for Potentially Could Be Blue. Or is it?

PCBWAAAAAAYYYYYY

Sorry, had to do it. In any case, it looks pretty cool 🙂

Pretty Cool Board!  (Has Peri already done that one?)

This may be the wrong place but Perifractic and the rest of the team will see it. I just watched David's Mini Pet video. Awesome as usual. He expressed concerns about people assembling a kit and it not working. I'm all in favor of selling the kits expressly WITHOUT a warranty. The person buying one should be capable of basic troubleshooting, just like David did. Maybe offer a warranty on the board BEFORE it gets soldered. Clearly if someone gets one with a scratch across a trace or merged traces, it could get replaced. That would just require an instruction to thoroughly inspect your board before starting assembly. Once assembly starts, its all theirs!

I get wanting it to be a complete computer but I also get that just drives the price, and development time. Like many. I'll buy one no matter what. But there is a certain satisfaction assembling the whole thing and then using it. Heathkit stuff was great! Another consideration, which I'm sure you did, would be to release the boards and a parts list so some 'Beta'  work could be done. Just like that Mini Pet kit. Having a few dozen users build and bench test them breadboard style could yield some interesting stuff. Either way, I can't wait to see one sitting on my desk 🙂 I

I agree, that troubleshooting kits could become a huge time consumer for the team behind this project, and that kits could be sold as "No warranty/support provided for kits."  At the same time, I suspect some very knowledgeable folks in this community could help one another in troubleshooting/diagnosing kit assembly issues, without impacting the core team.

Regardless of which way the team decides to go, I definitely plan to make a purchase!

I am in favor of kits being sold with an x16e "to verify correct functioning", and the kit being sold without warranty of soldered parts. Obviously the x16e raises the kit price, but that is also useful in indirectly filtering out people pursuing it without the skills to accomplish it. And even those who trash their build have a working system.
