Hi, there is a short version of description of my homebrew 6502 SBC, http://www.qsl.net/rw6hrm/html/6502sbc_en . Sorry for my broken english :rolleyes:
This SBC (named "Ayusha" :)) contains 47K RAM, 16K ROM (4 switched pages from 64K chip), 8255, 8253, 68B50. Programming at classic Basic.
Also described 300-baud text "dumb" terminal (25x40) with ASCII-keyboard and cassette interface (Kansas City Standard).

...idea from early 80's, but with "modern" chips. For replace *duino&Co ;)

Next step - connecting MM58167 RTC and 8-bit IDE interface...

Thanks for watching!

Fantastic design! Very 80's indeed, and the terminal is elegantly simple - hope you won't mind me trying to make one of those myself :)
Keep up the wonderful work! :)
