Hi everyone

I'm Oscar and I started learning 6502 by age 9 trying to understand how worked some Compute! games for Commodore 64 and Vic-20.

I forgot about it for a long time, until 2013 when I wrote Space Raid for Atari VCS http://nanochess.org/space_raid.html

More recently I'm working in Aardvark http://atariage.com/forums/topic/259694 ... i-vcs2600/

And lately in Atomchess https://github.com/nanochess/Atomchess-6502 for the Hackaday 1K Challenge.

Welcome Oscar! I've seen your chess pages in the past - splendid work, and very nice to see your work as a 1k 6502 chess project.

Thanks! Glad to be here

Welcome aboard!

Hello,

I'm Jean, from France. I'm joining this forum as a c64 owner and a former Apple II owner.
I never wrote any 65xx code but I recently tried to reverse engineer some games, that's why I'm here.

I think I'll also try to write a small c64 game when I have some time.

Welcome Jean! You should find plenty of resources here, and any help you need.

Welcome to our 6502/65C022/65C816 world.

Hello there,

my name is Arne. It is now pretty well 40 years ago when I turned on my first own µP, a SYM-1. Now a couple of weeks ago I unpack the SYM and to my pleasure it runs immediately. OK, some EPROM contents did fade but resting about 25y in the shelf and then ready on demand - quite honorable.

My µC yourney is pretty weird, I think I played with nearly everything that was somehow interesting enough: 6502 - 1802 - 6802 - 6809 (long time my working base) - 68000 - 9900 - 99000 - 68020 - 8051 - Amiga2000 - T801 - T222 - 68HC12 - TMS320 - ADSP2100 - ST6200 - AVR90S2313 - Scenix (fast PIC) - ATmegaXXX - AVR32 - STM32Fxxx - RasPi & clones - W65C265 so far.

The latter one reminds me of this forum, where I have lurked around from time to time - I don´t know when I visit here first time, some downloads are from 2003, but I think it must be earlier, say 1998/99 or so.

So perhaps if I have some more time playing with that 265, I could contribute something here...

Ah - if someone misses a certain kind of µP in the above list (something ending up in ...86) - it must somethinng that doesn´t inspire me enough ..

edit(1): typo corrections and adding 68HC12 (fuzzy logic era)

Reading x86 assembly language gives me a head ache, almost immediately.

Thanks for stopping by ... we're ready to listen, and help if we can!

Welcome Arne! Nice to see the T machines in your list there.

Welcome Oscar, I did notice your last minute entry to the Hackaday 1kB Challenge. It is a really impressive project. I thought it was the winning ticket.

My name is Dan, and my intro to computers was probably a used TI 99 4A my family found at a garage sale on the mid eighties. Around that time I was also fooling around with Apple IIs and PETs at school. As a child of the eighties, my early contact with the 6502 was the Atari 2600, along with an 800 and a 400 owned by friends. At that time, the Ataris were for games, and the TI was where I learned BASIC.

Somewhere in the nineties I got it in my head that I wanted to create a 3D graphics engine for PC. I never got further than a simple texture mapped terrain generator, but I learned allot in the process.

Later in life, I got interested in building tube guitar amps. I built a few, sold a few to friends, and still use one of y fest builds with a classic rock cover band I play in.

I always thought digital was beyond me, until watching a lot of Dave Jones's EEVBlog, which took the great away. I went from Arduino, to raw microcontrollers.

Every so often, someone on the EEVBlog forum would post a SBC they'd done. Usually a Z80, or 6502 thing. I always thought that was the peak of the hobby, and well beyond any powers I'd ever possess. Then I started reading this forum, and watching some 6502 builds on YouTube.

Yeah, it was complicated, but I was understanding most of what I saw. I then knew I could do this, and here I am!

Welcome Dan! I can relate to this. I felt this way about SBCs, FPGAs, address decode with discrete logic, integrating my 6502 with SD cards, running beyond 1 MHz. I just didn't believe that I'd have the long-term motivation to see them through, but with all the helpful, instructive, knowledgeable, patient, supportive, encouraging and thought-provoking people both here and across the web, I have achieved much more than I imagined possible.

Hello,
My name is Hubert, and I like to do things considered by many as impossible. My adventure with 6502 started in early 1990s, when I got Atari 600XL (second hand). Then I got another Atari (800XE), Commodore 128D(CR) -- real programming started here. I remember someone telling me that coding in machine code was too hard to learn, so I showed him that it is possible. My second assembly program produced approximation of a sine wave sound on Atari computer, and I was really shocked that it worked. First "program" made a copy of ROM into RAM on the same Atari so I could modify things later, but I wouldn't call it a "program" really

I like blinkenlights (search for CM-5), LED displays, gas discharge tubes and lamps, and electronics using glass and ceramic elements. I was playing with some relay logic before, even made some "telephone exchange" of my own (connecting two of 5 numbers).

Now I'm reading a lot, gathering information and collecting some chips to start building my SBC. Already got: a ton of SRAM chips (mostly 32K x8 15ns, some 20ns and 25ns), MOS 6502, MOS 6522, Rockwell 6520, some MOS 6526 and 8520 chips (replacements for C128D, when I connected radio modem to receive RTTY and blew the chip), some parallel FLASH chips (128K x8 and 256K x8, old BIOS chips, no need for programmer, AVR or STM32 can do it), two Rockwell 65C51 chips, and a ton of 74HC / 74LS / 74ALS / 74F chips, and similar, e.g. 54-ones and some Russian parts.

My first 6502 machine will run at 1MHz, just to get started. I also ordered some WDC 65C02 and WDC 65C22 chips too, so I will try to go a bit faster.

This is the past, I'm looking into the future now.

Cheers

Greetings Hubert!

Welcome to 6502.org!

Good luck in your 65 future, I'm sure you will have fun with it, even if there is no much glass and only tiny amounts of ceramics
