silly question:
how many instructions and registers would a minimal RISC be?
load, store, move, add, sub, nop, jump, beq, blt, and, or, xor, not, shift left, shift right, mul, div, rem, min, max, call, ret, sys, int?
general purpose, return addr, stack pointer, func args(x?), saved registers(x?),
maaaybe a time register and identity register, an interrupt masks register that can only be written by a privileged process... so a ring register?

｢ China’s top scientists have heralded RISC-V as a path to silicon independence. India just used RISC-V to make its first homemade microprocessor. Name a country; it’s probably experimenting with RISC-V. Brazil sent a record 25 delegates to the RISC-V summit ｣

Loving the days when I get the IPX Up and running (scheduled function test any 6 months)
Back in the UK after 8 years or so, heading to Cambridge for the CHERI Blossoms conference tomorrow! It's 12 degrees and sunny, that's pretty unusual for this time of year... 
. Looking forward to a slice of pizza at Aromi!

@cstross Wow! This is a great example of the power of virtual platforms, #emulators, and also disciplined state control in a programming language. The fact that you can run this inside a #pdf is also instructive — yet another attack vector.
Also, I’ll bet there are many packages out there to do cross-compilation from #RISC-V to other machines. Remind me never to use Adobe Acrobat.

@koakuma @techokami also #UltraSparcT2 as cool as it was at release (including dual 10Gbit-NICs and hardware RNG on die) has a lot of things noone would want to deal with in 2024 (i.e. DDR2-FBDIMMs).
Pretty shure @stman could write an entire curriculum on why #SPARC, #PowerPC, #s390x and even #ARM / #ARM64 should not be pursued and why #mc68k died alongside the unfixable-by-design mess that is #ix86 & #amd64.
Look, I'd love to get my hands on some Sun SPARC Hardware but aside from making my room hot and noisy there isn't much to justify blowing likely over half a Euro per hour (electricity price: € 0,40/kWh) just to have it up and running, as compared to a #PiCluster like those @geerlingguy had built multiple times are more practical.
And that's just bottom-billing, low-cost ARM SoC tech designed for a price tag (to the point that until the #Pi5 they neither included a power button nor #RTC onboard!
