* [[CPC Schneider International]] 11/1987, Page 097-099, Notes (?)
Notes: The "Centronics" board is yet another [[8bit Printer Ports|8bit Printer Port]] solution (but different than the [[CPCI 8bit Printer Mod|joystick-signal based one]] that was released a few months earlier in the same magazine). The Real Time Clock is somewhat similar to the [[Real Time Clock|CPCI Real Time Clock]] released in a special issue of the same magazine, but not identical (the RTC chip has different pin-outs, and some of it's 4bit registers are working slightly different, the leap-year bits, for example).
