    Planck computer design is in fabrication

    The Planck computer is almost ready for the big time. I received the prototype a few days ago and the build with through hole components was fine, except I feel it takes slightly longer to solder all the components when they are through hole, because you have to cut all those spiky legs off, and my side cutters are not very sharp…

    Redesigning for through hole components

    So feedback I received regarding the Planck 6502 computer is that some people are not comfortable soldering surface mount components by hand. I originally used surface mount components to save board space and because I find the larger ones reasonably easy to solder. Also, they are cheaper than through hole components.

    OPL2 sound card prototype

    I am having great trouble building a good VGA output card using either an FPGA or a microcontroller, so for a change I decided to start working on a sound card.

    Designing a complete extensible computer

    The Planck 6502 backplane can make a great retro computer if you add in the basic necessary boards. For the simplest possible configuration however, you need at least three boards : the backplane itself, the CPU board (which also contains RAM and ROM) and a serial board for I/O.
