+====== Proto65 Rev0.2, a 6502 SBC based on Protor5 ======
+===== Introduction =====
+This is the link to [[builderpages:plasmo:protor5:proto65:proto65r01|Proto65 rev0.1]], an older version without I2C bus.
+This is the link to [[builderpages:plasmo:protor5:proto65:proto65r03|Proto65 rev0.3]], a standalone 6502 system with its own VGA and PS2 keyboard interface.
+[[builderpages:plasmo:protor5|Protor5]] has a prototype area big enough for a processor, RAM and IDE44 interface. In this evolving project a 6502 CPU along with 128Kx8 RAM and an IDE interface are prototyped on a protor5 board.
