Ordered!
$30 with shipping!!!
Will keep you posted when it arrives!!!
Thanks again!!
And as it is new, it will not have The Bug, since all the buggy A2 and earlier stepping RP2350’s have already long been removed from the sales and production channels. (If you bought a new Pico 2W you could have gotten a stepping A3 rather than A4 RP2350 potentially, as the limited number of A3 stepping RP2350’s made went into Pico 2 and Pico 2W’s only – but even then, the only real difference between the A3 and A4 steppings is that the mask ROM in the A4 stepping includes some hardening of the boot process, nothing more.)
You must be an engineer….
You are Way too knowledgeable about this topic!!
I could learn a LOT from you on the programming side…
Now you know why my Avatar is Homer!!
I’ve always been on the hardware side of electronics…
Are you in the U.S.??
Are u an engineer?
And are u in the U.S.?
I could learn a lot from you…
I’m more hardware…
My new Pico is on order!!
From adafruit…
Thanks for all the great information!!
I’ve only been on this site a few days… but with your help and others, I’m learning a lot!!
I sent replies on the website…
Thanks for all the information!!!
I hope to stay in touch with you as you have LOADS of information!!
Now, once I get the new Pico from Adafruit, I’ll need to find out your recommendation for OS!!
Thanks again!!
Need more info on Zeptoforth…
When u have time…
I’m a software engineer by profession, and have been programming since I was eight. Conversely, my knowledge of hardware is mostly limited to digital electronics – my knowledge of analog things really stops at I = V/R.
I am from Wisconsin and have lived here most of my life except for a short period when I lived on the East Coast.
About OS’es to choose for your PicoCalc, I would try both PicoMite and MicroPython and familiarize yourself with both of them. Once you really know what you are doing with them, only then try out zeptoforth.
Note that zeptoforth is very powerful but provides very few guardrails to you as a user and requires significant discipline from you. You have to manage all memory manually and if you are not careful you can easily scribble on RAM with it. Stack overflow and underflow are only checked during interpretation and not during the execution of compiled code, and can easily crash the entire system. Overall, there are many ways to shoot yourself in the foot with zeptoforth.
However, zeptoforth does have features that makes development easier than in many Forths. For instance, it has local variables, which makes things a lot nicer despite being deprecated by many as ‘un-Forthy’. Also, it has a module system which wraps wordlists while being a whole bit more friendly than namespace control by manually wrangling wordlist primitives. It also has both structures and an object system, which when used well can improve your code design.
In general, though, zeptoforth is designed for a more experienced programmer in mind than PicoMite or MicroPython. As you are largely a hardware engineer a would suggest beginning with the latter two.
I wish that would be true 
Every RP2350 I have in my possession is A2, most of these have been bought in the last 6 months.
My guess is that the existing stock of A2’s hasn’t been removed from the distribution channels after all then…
Sorry I don’t know your name…
I need a little more help…
I got my laptop going and made a PicoCalc folder on the desktop… then downloaded….
PicoMite V6.02.00a and extracted it.
Now which folder do I pick to drag into the pico chip to make it work???
There’s 2 at the top of the long list:
“Pico Computer”… and “usb_host_files”
I’m guessing “usb_host_files”???
Please help… when you have time.
Thanks again in advance!!!
I have 3 spare Pico’s to play with until my new one comes in that you recommended!!!
Please stop doing anything at this moment. Your lack of information is dangerous. You should read as many posts on this forum and you should read some of the Pico resources on the web. Use your favorite search engine using words “Getting Started Raspberry Pi Pico” to find lots of articles.
Hacking the PicoCalc is an advanced subject and you need to know more about the subject before moving away from the programs on the PicoCalc memory card.
I’m just trying to get a chip to work on it…
I’m not trying to “hack” anything….
