I guess even the biggest carts are smaller than 64 kilobytes, which means that one static RAM chip is enough for the cartridge. > I've build a kit A/D interface which got power from the LPT port by > wiring together all data lines after putting the signals through > diodes. Thanks for the tip! I'll need the data lines for the application, though. I have three low-dropout diodes (0.2 to 0.3 volts) that I will try to apply to some unused outputs. If I have to use a separate connector for stealing power, I could as well use e.g. the cassette port on the PET side. I wonder why there is no +5V or even RESET line on the PET user port. > My guess is if you use the 74HC chip you might get away with it. Too bad there isn't any electronics shop nearby. When I bought the parts, there weren't any HC or HCT versions in stock. Marko - This message was sent through the cbm-hackers mailing list.
