Quazar OLED interface

Official site: https://2014.samcoupe.com/#graphicoled

Based on SSD1305 OLED display (128x32 version?): SSD1305.pdf

Uses 0x50 I/O port by default (fully configurable). I/O decoder uses 74HCT02 NOR gates and 74GCT688 8-bit comparator.

The SSD1305 chip is placed behind two 74HCT573 8-bit latches so it can be timed slower than Z80 bus.

Software

I have implemented a program to display images using instructions form provided manual:

  •  rc2014-oled - oled program for CP/M and PNG image converter.
