Funny Finding: Single Instruction Inline Assemblies for XBYTE
Kind of funny finding: While experimenting with my little XBYTE machine and PASM, I discovered, that single instructions as inline assemblies make sense. The reasons are, that P2's instruction set is very rich and that in 32 bit there can be 9bit operands as well. For example you can code "ret shl tos,#2" (register… -
Is there some single instruction like WRC but setting ALL bits?
Hi, for my Forth, at the moment I use WRZ and WRC to get a logic result as true or false onto the stack. However it would be better to have $FFFFFFFF for true instead of 1. I had a look into the list of instructions https://p2docs.github.io/p2_optable.html , but perhaps I have overlooked something? WRZ followed by NEG is… -
[flexspin][vfs] accessing fs structure/file-specific data from spin2?
Hey folks, Is something like what @Wuerfel_21 has done with a C object here (from MegaYume's fsadapter.c) #include#include #include char *get_name_for_dirent(struct dirent *d) { return d->d_name;}int get_type_for_dirent(struct dirent *d) { switch(d->d_type) { case DT_REG: return 2; case… -
Boot Loader Documentation
I don't see any documentation on the P1 boot loader. I see there is documentation for the P2 boot loader but not for the P1. Is this some big secret or am I not looking in the right place. I did a search and found a document for the P1 boot loader, but it is not found on the documentation page for the P1. Mike -

MIDIBox SID using two Prop 1s
So I decided to annoy TK and Wilba again. Been working on a MIDIBox SID idea for about a week now. And of course, I'm using SIDCog, because real SIDs and even Swinsids are more expensive than prop 1s. Concept is this: port the SID V2 firmware to a core module based around a STM32103 "Blue Pill". Iic 4*20 LCD, 2 gig SD card… -
Diy prop plug emulation using the ESP32?
I just ordered two propeller 1 40 pin chips and just now realized I don't have a way to program them. When Chip designed the Prop 1, his vision included a way to program them via RS232. As we know, the commercial prop plug emulates this. So it stands to reason that one should be able to use an ESP32 as an in circuit… -
Re: Asteroids conversion from 6502 asm to spin2 using Claude
I took @cgracey advice and changed it to plot. I did test it a little bit and it seemed to work, though I need to actually wire up some switches to see if it actually works well. I also changed the target FPS to 60.
