ddde The Commodore 64 is without ddde doubt one of the most ddde iconic computer systems of all ddde time and it’s Commodore’s finest ddde identified mannequin. However Commodore made ddde many different well-loved fashions, together ddde with the VIC-20, the Amiga, ddde and the PET. The Commodore ddde PET 64, which Commodore launched ddde late within the mannequin vary’s ddde life for academic use, was ddde Dave Luna’s first laptop. Sadly, ddde it bit the mud someday ddde within the ‘90s and Luna ddde was by no means in ddde a position to revive it. ddde In 2005, he tried to ddde transform it right into a ddde PC, however by no means ddde accomplished the challenge. Older and ddde wiser, ddde Luna was lastly in a ddde position to give the PET ddde new life as a docking ddde station ddde .

ddde Docking stations are available many ddde types with many various functions, ddde however the normal thought is ddde all the time to develop ddde a laptop computer’s (or pill’s) ddde capabilities. On this case, it ddde turns the related laptop computer ddde right into a desktop expertise ddde with a devoted display screen ddde and a full tactile keyboard. ddde The keyboard wasn’t really excellent ddde within the Commodore PET 64, ddde however Luna has plans to ddde improve it with a MechBoard64 ddde to maintain the unique look ddde with fashionable high-quality mechanical keyswitches. ddde Because it stands, the PET ddde 64’s keyboard connects to the ddde docked laptop computer and a ddde 12” TFT LCD display screen ddde (rather than the PET 64’s ddde unique CRT monitor) acts as ddde a second monitor for the ddde laptop computer.

ddde The display screen connects to ddde the laptop computer via a ddde WAVLINK USB 3.0 DisplayLink adapter, ddde however the keyboard connection is ddde extra complicated. As a result ddde of the PET 64 was ddde an all-in-one laptop, the keyboard ddde interfaces immediately with the mainboard ddde in a fashion much like ddde in the present day’s laptops. ddde There is no such thing ddde as a USB interface or ddde standardized output in any respect. ddde For that motive, Luna needed ddde to create his personal adapter. ddde He used an ddde Arduino Micro ddde to scan the keyboard ddde matrix’s rows and columns on ddde the lookout for key presses. ddde When it registers a key ddde press, it sends the corresponding ddde character to the related laptop ddde computer through the USB connection. ddde The Micro seems as an ddde ordinary USB HID keyboard, so ddde it doesn’t require any particular ddde software program.
