    (Cross post from the PiDP mailing list)

    Another status update, this time a big one -- I'm done with nearly all of the hardware:


    Data breaks fully implemented according to the real...

    That's correct, but since the posibus and data break interfaces are implemented exactly as on a real PDP-8/I including proper timing, I want to make sure to pick a realistic set of peripherals before...

    Ah, so it's just a newer generation without additional features? Sounds like the TC08 is more fitting for a PDP-8/I then, thanks!

    DECtape TC01 vs TC08: Differences?

    Hi all,

    I'm implementing a few peripherals for my PDP-8 project. I started with the TC08 DECtape controller and wondered how it is different from the TC01. The Small Computer Handbook only states...

    Great to see another SoC project! We're using very similar technical approaches, e.g using memory mapped I/O to communicate between the ARM and the FPGA. I haven't ported my project to Cyclones yet...

    Hello!

    Hi all,

    I'm new in to this forum and my plan is to stay. My main interest are early mini computers from the 60ies to 70ies, especially DEC PDPs. In my day job, I'm an embedded software engineer...

    Small status update: I've started implementing the software part. Decided to create a small custom Linux distribution using Yocto that runs node.js to control the FPGA and peripherals. The software...

    Thanks for the warm welcome!

    Regards the Omnibus device: I don't have any real PDP-8 hardware, so I wouldn't be able to design the hardware part for this. But the VHDL code exposes the system bus...

    PDP-8/I: New SoC implementation

    Hi all,

    I recently bought a PiDP-8/I, Oscar's replica of the PDP-8/I console. I really like the console, but the actual system is implemented on a Raspberry Pi using SimH, i.e. the hardware is...
