Cart64out is a breakout board for the Commodore C64 Expansion Port
All signals of the C64 expansion port are connected to a box pin header. This way, they can be displayed with a logic analyzer or an oscilloscope. A helpful feature for analysing the functionality for a cartridge. Some configuration and chip select signals are connected to a jumper, hence they can be interrupted by pulling a jumper, which might be useful for copying a cartridge. To provide a perfect timing for this, a micro controller could be connected to the Jumper JP1.
Also the signals from J2 can be connected to a bread board. The two GND and two +5V pins on JP1 are intended for this purpose.
This revision is a derivative of Rev. 0. It offers two additional mounting holes, in case this board is used to be an extension of the port (not tested, yet).
Rev. one has four mounting holes and additional signals (/IRQ , /NMI and /DMA) on the pin header JP1.
The compnent prices (PBC included) were summed up. The total costs are 2.99€ (depending on the part sourcing). No shipping fees are included.
