    • Hi Boomer3200   Thank you for taking the time to summarize these findings, the knowledge is invaluable for anyone wanting to tinker and explore an old classic. I look forward to the new topic that you plan on posting sometime in the future. Thank you, much obliged.
    • I don't know about converting video formats but will mention that some of the video cards use Xilinx FPGAs which are configured by their driver.   In other words the FPGA doesn't know what it's doing logically, until the driver loads and downloads a bit stream to the FPGA on the video card.
    • Yeah, if the AVR internally generated RC oscillator is at least as good as Raspberry Pi's small, 19.2MHz crystal, you can easily get ahead/behind by 15 minutes a month, versus 1 minute a month or less with a good stable 32.768kHz crystal.  With NTP time sync, you really don't notice, but if you want good old retro time keeping, a design without a good 32.768kHz crystal in the loop leaves much to be wished for.   Also, another note I should point out, the internal load capacitance of the ATTiny85 when using a 32.768kHz crystal for the system clock invalidates the external capacitor selection of 10pF and 33pF, so the crystal connection cannot be used as a drop-in replacement also for this reason.
    • Just trying to run the included X11R6 or X11R5 on the Mac. Before trying to do anything too heavy with MachTen I'm going to get some more RAM for this thing anyway (or use my Quadra 610 when I can get to it next).
    • That’s exactly what I was thinking. Any damaged display cables I’ve seen resulted in very different forms of visual artifacting compared to what I’m seeing on the 180c   Thanks for chiming in, makes me feel better. I wasn’t keen on trying to find a display cable; 180c specific parts like that aren’t easy to come by
