C64---Cart64out

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.

Rev. 0a

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. 1

Rev. one has four mounting holes and additional signals (/IRQ , /NMI and /DMA) on the pin header JP1.
