I need to stop inventing new #RetroComputing projects in my head.
Otherwise, I'll soon find myself coding a racing game and a vertical shooter on the #AmstradCPC

My system 7 project is continuing at a good clip, ps/2 keyboard input, sb16 emulation and started converting the pascal and assembly source for macpaint from Bill Atkinson to C also for inclusion #RetroComputing #macintosh #OpenSource https://github.com/Kelsidavis/System7

I am almost certainly going to add some kind of programmable computer to my game. Thinking of making it programmable with assembly and basically implementing something like a 6502 VM that runs a handful of instructions per game tick. But I'm not entirely sure whether to make it an *actual* 6502, or to just make a similar but simplified ISA
Kinda tempted to do the second one, because 1) making ISAs is fun and 2) standard 6502 assembly is ugly so I'd wanna make some changes anyway.. #gamedev
Alright I have designed a little ISA: https://gist.github.com/mortie/d678c4663fe705219e5dfe90e0bbdc3d. It's somewhat 6502-inspiret, but I think it's cute.
Not done yet, but I think it's a decent starting point. Next step: writing a VM and an assembler...

History of the GEM desktop environment
The 1980s saw a flurry of graphical user interfaces pop up, almost all of them in some way made by people who got to see the work done by Xerox. Today's topic is no exception - GEM was developed by Lee Jay Lorenzen, who worked at Xerox and wished to create a cheaper, less resource-intensive alternative to the Xerox Star, which he got to do at DRI after

North star coffee, then you need a z80,cpm and s100 bus start in the morning.
I wanted to find a small niche hobby coding project that approximately nobody would care about.
I'm tooting about it now, and I don't expect you to care.
I want to use m68k-linux-gnu-as cross-assembler, but it doesn't support the Motorola syntax the original Amiga tools did.
How hard can it be to write a preprocessor that converts vasm mot syntax module compatible assembly to GNU as?!
Turns out, less trivial than I thought.

Pretty good #C64 hardware rundown/comparison for the uninitiated.

Me, looking at the 8008/8080/Z80 instruction sets: "bah, why do you need conditional calls and conditional returns when the conditional jumps are already more than enough?"
Me, coding in 68000: "I really with I had conditional calls and conditional returns, relying on conditional jumps makes the code harder to read than necessary."
I am never happy.

In my little world of #RetroComputing, I have stumbled across minor issues in some of the tools that I use.
I've had two cases so far where maintainers very quickly took my suggestion and made it available in their main branch. I've also had one where I haven't heard back from the maintainer, i.e. where I'm going to need to maintain my own fork (for #RiscV compatibility). And that's OK. Beyond being glad that I got help, I'm glad that the original authors allow me also to do the work myself.
