  1. I have created several 6502 based, and also avr-based boards. Either through-hole or smd is fine. I've put in a significant investment in a JBC soldering station with more tips than would be wise, but alas, hobbies being what they are . Recently invested in a good digital microscope for smd, indispensable for smd ICs with lots of pins. I would certainly be able and willing to solder an x16 kit, even willing to solder a few for other people to get them started.
  2. Hi, A while back, I created an overview of the 65c02's registers, the most important mnemonics and the relation between them. Now, this presentation is far from perfect, but it may help you as well. Enjoy! Register overview.pdf
  3. After a cooldown of a few days, I have changed my mind. My initial response was no/no/DYI, driven from emotion primarily. I have built my own 6502 board from scratch. In fact, two versions of it. While developing software, guess how many times it was actually interesting that it runs on discrete ICs. Not many. After implementing an XModem bootloader, I didn't even have to touch the EEPROM at all. Finally. I did however quickly felt limited by the I/O options that I built in. It has a PS/2 keyboard and serial I/O, but video is still lacking. Then I got engaged with the X16 and built software for the emulator. My 6502 boards haven't been powered on for some time now. In retrospect, even without knowing all the details from the X8, when this would have been the first option presented to me a year ago, branded as X16, I would have been sold. Sure, bank switching, I/O slots and a dedicated sound-chip are interesting future options. But given the power of the VERA, I'm not really interested. So please, deliver the X8 as the first option (with the cool keyboard ). I'll rewrite my sokoban clone when I have access to the emulator. Indeed doesn't sound like much work.
  4. Hi all, I just created a forum account and would like to make a quick introduction. I've been dabbling in electronics and 8-bit computers over the last few years, especially during the lockdown. Assembled an FPGA-based C64 last year, based on a Gideon's Logic Ultimate 64, a new case and a great breadbin keyboard from a failed original c64. I designed a small PCB for its user port, to light up 8 leds or an LCD screen, selectable by jumper, and programmed it in assembly. If anyone wants the gerbers to print their own PCBs, let me know. I then found Ben Eaters videos last year and started a couple of 6502 PCBs and software projects, where the largest project has a ROM bootlader enabling dynamic loading of programs over the serial port by xmodem protocol. Pure magic, to create something like this from scratch. Then when I thought I was done with the 6502, the x16 started to look more and more promising to me. So I started programming a Sokoban clone for the emulator, which I uploaded today. I first had to create some code to convert available sokoban (rosetta) ascii to a usable binary format. This binary is included with the program in a single PRG file, so it works in the web-emulator. When the final x16 hardware arrives, I'll create a version to let the user select their own levels. Ok, enough about me. I'll be cheering the project on as best I can. Keep up the good work! Jeroen

    A Sokoban clone for the Commander x16. This started out, mainly to see if I could grasp the concepts behind the x16. No sounds or music, since this is a pure puzzle game. I have put in a fun level set called 'Sasquatch IV', publicly available at http://sneezingtiger.com/sokoban/levels.html. The code for this game can be found at https://github.com/envenomator/x16Sokoban.git Have fun!
