Has anyone tried running RISC OS on their RPi? It's not Unix/Linux and certainly isn't Win*lows! It's definitely a different beast and it's speedy.

PI EOLs (was: RPi5 in stock at Dallas Microcenter)
This page claims to have collected the EOL committments for the various versions... Pages have statements like "
Obsolescence Statement
Raspberry Pi 3 Model B+?will remain in production until at least?January 2028"
Now whether "will remain in production" means actively in production or is really "if we get orders and can source the parts" is a different question.?

Re: RPi5 in stock at Dallas Microcenter
Sorry all that I have just been lurking and not participating for about a year, work is nuts, plus some family health challenges for the last 18 months.
?
Still alive and kicking, as much on my plate as before, if not more.

That’s awesome news about the 3b+ (for me). $35 – not bad. Chinese gray sellers are going to be very unhappy.
?
Thanks for the update Rusty!

Oh, and Mouser has almost 12,000 3b+ in stock!
I don't believe that the 3's or 3+'s have gone EOL yet.
Supposedly, they'll keep making them until the need?

Microcenter has a supply of RPi4 in stock.
DigiKey has over 6,000 RPi4 w/ 8GB of RAM
but none of the ones with less RAM.
DigiKey also has a good supply of RPi5,
3,000+ of both memory configs.
Mouser still doesn't have RPi5's in stock
but gobs of RPi4's of all models.

OS/2 Archive Shutting Down
Hi,
After 34 years, an OS/2 archive is shutting down. The site is apparently
mirrored, but a bit of history is going.

They sure do... got trigger-happy, so there's both the 2x8MB PSRAM and a regular version on the way. Let's see how quickly ProtoSupplies delivers.

Mouser down in Mansfield has a pretty good supply of RPi 5B w/ 4GB of RAM. The 8GB boards are still on order.

They sure did but those "cores" were really more like arithmetic units and I believe they were all programmed to do the same thing at once. Thusly, they weren't quite like another core.? ?A Cray was SIMD -- Single Instruction Multiple Data -- one instruction with multiple data items.
To quote Wikipedia:
? ? "The Cray-1 was the first supercomputer to successfully implement

Mind you the CPU that fed this vector processor was something like a Data General Eclipse (I've also heard of VAXen) being used at the MCU which setup the vector processing and fed the CRAY-1 with all the data.
Even with a single core at 2-3 GHz, a RPi would do some serious a$$ whooping on this 1974 design.? :D

Re: RPi 1B faster than a Cray-1?
80Mhz was a boatload back then. Affordable gear end of the 70s ran at 1-2,
maybe 4MHz tops.
Gotta wonder what it would take to emulate a Cray-1 so that it matches the
original's performance.
