Dick Smith Wizzard (CreatiVision) MultiRom v1.0 Test & Upgrade
The Creativision console was given to me on loan from a friend, Andrea Pierdomenico for testing the MultiROM v1.0 cartridge made by Treviso RC (Francesco Brolli)
I and Andrea we realized that the power supply was lost (tragedy). The original power supply of the CreatiVision uses 16v in AC 350ma and 9v in AC 1amp.
Here comes Ciro (Ninetyniner Iuc) that months ago gave me a transformer extirpated from a unknown motherboard and with a bit of fortune there are all voltages.
At this point, given the poor quality of the output video via antenna that comes with the Creativision i have decided to make the easy Composite Video/Audio mod and acting on the Trimmer (color gain) native on the PCB of Creativision i have reached a good quality of the image.
I must thank Andrea Pierdomenico, Ninetyniner Iuc and Francesco Brolli (Treviso RC) for the MultiROM Cartridge v1.0.

…e Andrea e Ciro non ti hanno detto che hanno potuto provare un Wizzard e la MultiROM di Francesco al “Brusaporto Retrocomputing” in cui ci siamo incontrati? :-D
Se hai bisogno di altro materiale, schematiche o informazioni, ti invito a visitare il mio sito “CreatiVEmu”. Peraltro la cartuccia di Francesco si puo’ ordinare anche da li’ :-)
Saluti!
