Oh yeah.. A bit more progress catching on the SX20 'blog'

So far, I've added pics from the Timeline of 2018-2020, (49 Images and tons of tripe). Like, who knew that a #ZXSpectrum makes a cracking bracket. :D

I have too many projects in parallel in this moment, so I’m glad I could manage to finish at least one of them, the C64/VIC20 CR power supply built around s decent switching power supply for the 5V. I received the cable I needed today and finished the assembly. The output is pretty close to 5V and the voltmeter is a little off, but everything works and my #C64 seems to work perfectly well with it. #retrocomputing #DIY #electronics #VIC20

RE: https://mastodon.social/@keyboards/116484578081746002

IDK if the #VIC20 was different, but I love how the #Commodore64 had an NMI key (Non-Maskable Interrupt), the RESTORE key. That means that when you press RESTORE, an interrupt is triggered which can't be ignored in hardware by the computer. (Of course, it can be ignored in software with, I guess, an RTI instruction? #6502 )

I've used it to mess with programs that are timing-heavy (like demos) or don't seem to have the interrupt vector set up :) #C64U

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

1 N=20: L=INT(10*N/3): DIM A(255): Z$="000000":T$="999999"
2 FOR I=1 TO L: A(I)=2: NEXT I: M=0: P=0: FOR J=1 TO N: Q=0: K=2*L+1
3 FOR I=L TO 1 STEP -1: K=K-2: X=10*A(I)+Q*I: Q=INT(X/K): A(I)=X-Q*K: NEXT I
4 Y =INT(Q/10): A(1)=Q-10*Y: Q=Y: IF Q=9 THEN LET M=M+1: GOTO 7
5 IF Q=10 THEN PRINT STR$(P+1);LEFT$(Z$,M);: P=0: M=0: GOTO 7
6 PRINT STR$(P);LEFT$(T$,M);: P=Q: M=0
7 NEXT J:PRINT STR$(P)

Working within constraints is kinda fun in some way. But wasting 2kb just for a couple of redefined characters is kinda wasteful. Maybe I'll just stick to the defaults.
