Did some Pic assembly back in the 90's, remember having to count instruction cycles to get the timing right. None of that now with C and arduino! Ah the good old days.
This sounds really interesting. I have read a couple of books about basic computing but my old grey cells struggle a bit so I'll definitely be following along to see what I can learn and if it makes it all become a bit clearer! Is this going to end up with a Ben eater size board? Anyone deciding to try this I'd advise you don't skimp on cheapo breadboard as connections can be fairly ropey! Looking forward to part two!
Breadboards are only for temporary tests. A good connection to all used components is important and a very good power supply for every chip. It’s a good idea to take a design tool for a PCB if you know how to connect your components. Production of a PCB is cheap.
@@paulkirchhof9546 absolutely, but the breadboarding does allow for testing and experimentation in the early stages. It's also good for beginners to follow and get a better understanding of the circuit, imo!
6809 is better then the 6502. if you like it fast and have some ASM-Code then the faster 65816 with 14 MHz is a good choice. 8-Bit still lives and programs are shorter then the code for 16-Bit and 32-Processors. I like this kinds of projects .today we have better ROMs and RAMs but no Chip for HDMI-Output . A fast 10“ TFT for graphics is a good alternative instead of the old VGA. For education is VGA great but to old.
built the Elektor 6502 single board computer in the 80's, thanks for re-kindling the intrest, looking forward to following the series
Great! - Looking very much forward to this series :-)
My favorite topic. Keep it up

They do make them new. You can overclock them to 25Mhz no sweat, people have done 40mhz... Let's go!
Awesome

Top tip and something I'd not given much thought too actually. Thank you.

Memories, had a zx81 and did some 6502 asm on C64 years ago. I would say excel, but prefer calc.
Started off with an 81 myself also, then a oric 1.... Please don't judge, I was young!
@@XTronical said in a whisper "Atari 400" lol
That had the membrane keyboard didn't it? Like the zx81?
@@XTronical yes, and a cartridge slot on top. I Wanted the 800 but too pricey back then.
