For anything more sophisticated than your coffee pot
the RP2040 from
Raspberry Pie is a fantastic little chip, dual core 133 MHz Cortex M0+
with 8 PIO engines, 264K of RAM, ADC, UART, SPI, I2C all for under a
dollar. I designed a fully functional RP2040 with 16 Mb flash for under
$2.00. In large enough quantities that's encroaching on 8 bit PIC
territory at over 1000 times the memory and CPU power.
I am wishing for a Quality Product, cheap crap is not always better.
USB comes to mind.
256Kb ram is only 32K 64 bit words. Cache memory never works.
My $5 internet toaster, just exploded after 3 days.
So what? Just buy the new model that works with windows 12.
Download a buggy new tool chain. The Z80 tools worked.
The PDP8 was built to last. 50+ years and going strong.
NOT the crappy PI PDP-8 or PDP-10. I give it 2 years max.
Now a PI style computer with compact FLASH x 2, NO USB
and 2 MEG ram , real serial and printer ports that will work
in a noisy industrial setting, would be quite usefull.
I'd pay even $3 for it. :)
