    I used a fiberglass pen on the legs of the chips to shine them up a bit from the dirt.

    I tried a few things that I didn't mention.

    I did resit the chips in the sockets, that didn't do anything.

    On a hunch, the first thing I put onto the socket was vinegar, and it reacted. So I guess some battery juice got in there from…

    Hello,

    When compared to a new socket the old sockets looked really nasty and corroded. So I changed all 5, Ran out of 20 pin slim dip sockets so I substituted for one.
    I don't have a desoldering gun so that was very annoying to do.

    Wooooooooooo, that would…

    So update.

    As a shot in the dark I removed and inserted all the socketed chips, twice and it worked after a good squeeze.

    I guess the IC sockets are really crusty, I guess I'll change them at some point to avoid this happening again.

    Hello there

    So a bit of an unfortunate update, my only ISA vga card died.




    I saw it fail about half the screen was covered in random characters that are caked into its Rom so I'm guessing that one of the two Rom Chips have died.
    It was just random when I ran…

    Hallo!

    Placed an order with JLCPCB, including the SMT assembly.
    Had to change the value's of the resistor dividers but that's fine.

    I ordered 15 boards with SMT and 5 without, I wanted one for decoration.
    So, here's hoping that I didn't mess up anything…

    So I got around to adding that fabled pin 8.

    Unfortunately most of my time for today was wasted on the SDK that decided to no longer work after an update.
    I reinstalled everything and it still won't work. No idea what's wrong, at this stage I'm just…

    With the C SDK the Pico comes on instantly, I haven't noticed any delay at all. With Micropython/circuitpython there is a definite delay.
    There is already a hack in the pico, if it remakes a connection with the USB mouse after it had lost it's…

    I don't know yet. I'm going to have to experiment with it on my breadboard, I have it wired up on the breadboard already.
    I know that serial mice don't seem to use it, none I've seen anyway but there is a weird bug in the firmware that…

    Okay, I was looking into this trying to figure out what was going on and I think I figured out the source of the issue.

    I based the names on the silkscreen on the pin out of the female DB9. So we both used pin 7 for init but you called it…

    I was thinking about paying the extra to have the SMD parts done for me, it would save time and fiddly work.
    However, I do love a dip switch and I do prefer a little 3mm led to an SMD one, just easier to see if it's lit from the side.

    Have to have the values where possible, having to look up at an excel sheet while soldering sucks the fun out of it!
    R4 and R3 don't have a value because I'm not sure what I'll set them to. I'm thinking 1k or if I can get away with it…

    Well that answers why you used RTS, I was wondering why you did that.
    I'm a little confused about this though "max232 has not enough inputs."


    RTS is sent out from the max232, so can't I just plug into pin 10 of the MAX232 from the pico?

    Or…

    Hallo!

    So today/tonight I worked on the silk screen.
    The board is pretty much the same but I tried to refine it a little more. A few traces got moved around to less silly places and I added a taper to on the board towards the serial port.

    It needs a name…

    I got a bit carried away and done all the tracks, keeping the pcb as narrow as I can. I really don't think I can narrow it down anymore without mounting the rp2040 directly to the board OR swapping out the DIP switch with something else which I'd rather…

    Since the usb data lines are not accessible from the pins on the sides of the pico, I thought it would be a bit messy to run wires to the either the test pads or to a micro usb cable from the board.

    Guten Tag!

    So I have been tinkering with a PCB and how to lay out the board.
    I tried a few idea's but I stumbled on a shape I like. Before routing traces and making it look nice. I'd like to ask what ye think and if it's missing anything important.

    Just for…
