It will support PS/2 keyboards and VGA. Intended to be a learning platform for RISC-V coding, it's only got 2k of RAM. (I tried finding a 3rd party source for this announcement but I struck out, so I'm linking the actual olimex webpage. Not affiliated with them, just thought this looked neat.)

I'll believe it, when I ordered one for $1.

Yeah it's a "PC"

[–] [email protected] 39 points 1 month ago (1 children)

I don't think defining a microcontroller kit as a PC is an accurate description.

[–] [email protected] 5 points 1 month ago* (last edited 1 month ago) (2 children)

Some ARM CPUs that are advertised as microcontrollers have 32 bit address spaces and roughly the same power as an i486.

[–] [email protected] -2 points 1 month ago

Yeah nah still in micro controller space. When you say PC it comes w with up to date expectations attached and VGA is not one of them. Or 2k RAM.

[–] [email protected] -2 points 1 month ago

A CPU on its own cannot be a microcontroller alone via its definition; as a microcontroller contains a CPU and other needed components to drive it.

No microcontroller is going to beat a computer with a modern microprocessor on complex computing though. But it's good to know tech is still improving on all sides.

While I understand some of the hate in the thread, I appreciate someone creating something for us old timers. Working within the constraints of a system and making things work was a real satisfying experience.

2K of RAM? Time to port over some Atari 2600 games!

[–] [email protected] 7 points 1 month ago (1 children)

Even at this price point isn't it more economic and sustainable to emulate a RISC-V device with already owned hardware. Especially since it's so low powered.

[–] [email protected] 10 points 1 month ago (1 children)

And an emulator doesn't require you to find a PS/2 keyboard.

[–] [email protected] 9 points 1 month ago (1 children)

You mean the agony of deciding which one to dig out of my bin of PS/2 keyboards?

[–] [email protected] 1 points 1 month ago (1 children)

I'm not going to say I definitely don't have a PS/2 keyboard somewhere in the basement, but that box got thrown away at least a decade ago.

[–] [email protected] 10 points 1 month ago (1 children)

Bet you feel like an idiot now!

[–] [email protected] 1 points 1 month ago* (last edited 1 month ago)

Nope! Didn't even have to go out of my way. Turned up while I was looking for something else.

[–] [email protected] 3 points 1 month ago

Sounds groundbreaking for 1997.

[–] [email protected] 2 points 1 month ago (1 children)

So basically something like this only a whole lot LESS capable? Although if you specifically want to do RiscV coding then it does limit your options.

[–] [email protected] 1 points 1 month ago* (last edited 1 month ago) (1 children)

The esp32 doesn't have VGA.
I seriously doubt you can get these special Esp32 that have VGA and USB for $1 USD, I can't find pricing on any of them.
Cool concept though.

[–] [email protected] 3 points 1 month ago* (last edited 1 month ago) (1 children)

The board costs about $10, I have one on hand. Besides VGA and PS/2 ports, it also has an audio-out jack and a slot for SD cards. And if you want to compare specs, the ESP32 blows this away. Sure $1 sounds impressive, until you realize just how little you can do with it.

[Edit] Looks like the price has come down under $10 for this board now, here's a link to get them from China.

[–] [email protected] 0 points 1 month ago (1 children)

Thanks.
Funny, for me it shows $12.01 USD.
Now that's 12 times the price of the Risc board, so of course it has to be more powerful.
If you make it another 12 times more expensive, you can have 4 Raspberry Pi or compatible, that are also way more powerful.
Add another 12 times to that, and you can have a full blown gaming PC.

Again it's a coll concept, between an Arduino and a Raspberry PI.
Unfortunately it's useless in many cases, because they've removed access to the pins.

Unfortunately it's become pretty hopeless to order from China where I live. We pay $30 declaration fee, and on top of that 25% tax.
We still have a couple ESP32 left from before they tightened the rules on imports for personal use.

Hmm I'm seeing a sale price right now, might be based off my order history though. I found another that has a standard price of $10.39, but all the ones I looked at are now also including a shipping cost around $4.50 so that jacks the price up even more.

All these taxes and tarrifs and what-not are really hurting people's ability to get access to affordable items. I was looking at some solar panels right before the US added a tarrif to those items, so now I'll wait to see what happens.

[–] [email protected] 1 points 1 month ago (1 children)

They must have different prices for different regions, I'm also told the "normal" price is Kr 109,82 DKK = $16.16 USD. Shipping is $7.71.
If it was sent from EU when sold to EU, so there wasn't any import fees or taxes, it would be very nice, but these sites rarely write where they are shipping from.

[–] [email protected] 2 points 1 month ago

If you're curious enough to get one, I've seen them on ebay as well. Might even be available on Amazon. I think they've been around for a couple years, I just got mine in April but still haven't had time to fire it up and play with it.

The OLPC reborn. You can probably by one for a child in a developing nation for $1 while purchasing one for $300 for yourself.
