I'm declaring my house part of it's own time zone that is 1.10 minutes in front of BST.
It is therefore time to stop working.

Needed 2 batteries for my calculator. £4.50 for a pair, or £3.75 for 50 !

100% agree, plus you can get older versions to match your ageing OS. Last year, I installed it on a windows 2000 box :)

Neo-pixel and SPO256AL2 test, from an MBASIC program running on CPM/80 on ROMWBW on a Pi Pico emulating a Z80 ;)

Run RomWBW (z80 emulated CPM) from a PI Pico using RC2040 PCB http://extkits.co.uk/rc2040

Rom WBW running on a Pi Pico ( the old type )
Just an experiment at the moment, I'm not proud of some of the bodges. Needed to fit 512K Ram and 512K ROM into a pico.
Runs CPM though, although there must be some (a lot of) broken stuff.
Need to experiment further into selecting the ram pages in the build of ROMWBW

Ok, its not my code, reverted to SDK 1.5.1
all compile and work fine.
Maybe I'll try again at SDK 2.0.1 :)
Or with a separate machine for RP2350 stuff.

Not a single thing I've written for rp2040 works with SDK2, but the examples seam to run. Biggest issue is with spi can't find any solutions on line and I don't have the time to debug.
So, it could be my code, but...

2024-08-13 16:22:18

Too much is broken on the Pico SDK2 I'm looking at reinstalling 1.5.1 and wait for the edge to stop bleeding.

The nice thing about working with older OS's:
There are books.
Books are cheap.
After you go on a holiday, the OS is still the same

I believe that to be the case from what I've read.
Although as the code must be different how you move from one core to the other is,,, interesting ?

2024-08-08 20:49:34

Is #RaspberryPi looking to move 100% to RISCV ?
Well, there's no arm in it I suppose.

If asking for directions to walk to a place was on an Internet technical forum.

"Catch a bus, the driver will know"
"Why do you want to go there xxx is better"
"You are using the wrong shoes, try £5000 worth of wellingtons"

"Don't walk trains are better"
"Turn right before you get to the bridge"
