Tested various micros running this FLOATING POINT program. It derives Pi to 20 decimal places. Interesting stats.

@gmc I didn't see the #amstradpcw ever, but now I learned, that its name was Amstrad PCW and the same from german Schneider was called Joyce.
And yes, you are right, the DMP3000 wasn't part of the PCW/Joyce system. -

It lives!
#amstrad #pcw 9256 resurrected!
Having got it working then shorted the psu on the floppy housing (🤬), converted to USB-C PD.Lots of capacitors replaced and the image is almost stable (a few ~100v caps still need doing as I don't have anything above 50v in stock).
Pleased :)
Now just need to make a #cp/m boot disk!
(Back connector on #thingiverse if anyone ever needs)

I should do, or even redo sometime in the future, an #introduction finally.
I'm from Poland and have grown up with an #AmstradCPC, which made me two things for life: a #Software engineer, and an 8-bit retro enthusiast.
Today in my home you'll find: all the #Amstrad CPCs, an #AmstradPCW, a #MegaPC, #Atari 65XE,130XE,800XL, a #C64 and a #C128, #Amiga 600 and 1200, a couple of #MSX and #ZXSpectrum, some obscure ones like #OlivettiM20, old AT PCs, old laptops, printers, a #PowerMac and... a ps5.

I’m Jez from the #UK. I’ve been employed as a #SoftwareEngineer since 1994 in a variety of companies. I have also made #iOS games and contributed to #OpenSource Projects including #Groovy
I was inspired to code on the #Atari400 in the early 80’s, followed by the #BBCMicro #AmstradPCW #Amiga #PCXT and #486 PCs, I still use most of these and the #FPGA #retrocomputing remakes
I also design #MechanicalPuzzles, and enjoy the theory and technique behind #CardMagic
Cheers
